inspiredtobe forthoseinspiredbygreen,writtenbytheexpertsingreen Free Publication January - February 2010 Dear Inspired Reader, I am very happy to introduce myself in the first issue of 2010. Mr Kishore Kumar, Owner of Inspired to be Green Magazine, gave me the great opportunity to manage the green magazine from now on. Together with the team of Inspired to be Green we are building the platform for India’s Green Building community. Since I came the first time to India, I am fascinated from this country. Every day is full of learning experiences, challenges, lovely people and excitement. Born in the heart of Europe, Austria is one of the most advanced countries for energy efficient buildings and technologies. I graduated from there as an engineer for eco-energy and energy efficient buildings. Maybe it was just not challenging enough to design another net-zero or solar passive building in Austria or maybe it is just the open minded people in India who convinced me to be part of India’s Green Building Movement. In India I worked on solar airconditioning, energy-efficiency improvement for hotels, as well as on energy modeling and LEED/IGBC projects during my time with Spectral Consultants. To be a LEED accredited professional and certified for energy and quality-management from the TUEV Germany gives me a good understanding of the process involved in an energy-efficient building design. I love to see so many new ideas and green projects coming up in India, and to get to know the people behind these great projects and companies is a wonderful work. I know that we have everything required to make the green building movement to a success: expertise, innovative product manufacturers and builders who are ready to take up new ideas. Sharing our knowledge and experience will help us in the future to make buildings more energy-efficient and ecological. I will work with passion, and a lot of motivation for Inspired to be Green – and I hope you will support our initiative. Stay inspired, Isabelle

Dr. R K Pachauri, Director General TERI 1. What inspired you to take up “the journey on the path of green”? What inspired me to take up the journey on the path of green stems from two factors.Firstly,IwasbornandspentagoodpartofmychildhoodinNainitaland in the beautiful surroundings of mountains nestling a large and placid lake. Extended exposure to the beauty of nature at such an early stage of my life left a deep impression on my sensibility related to green issues. The second reason lies in the fact that when I became a researcher I initially worked on energy issues and realized very soon the major environmental implications of the entire energy cycle, including the accumulation of greenhouse gases, which have led to human induced climate change. 2. In what profession or on what project were you working 10 years ago? Ten years ago too I was Director General of The Energy and Resources Institute (TERI) and essentially involved in building up this Institute. At that stage I was also the Vice-Chairman of the Intergovernmental Panel on Climate Change (IPCC), and played a significant role in several activities related to the preparation of the Third Assessment Report (TAR). In those days I also had time to carry out some research myself which unfortunately has become increasingly difficult now. 3. What is true sustainability in your view? In my opinion true sustainability is based on a practical understanding and application of the very simple definition in the Brundtland Commission report which essentially defines sustainable development as that form of development which meets the needs of the present generation without compromising on the ability of future generations to meet their own needs. 4. What does a day in the life of Dr.Pachauri look like? My life involves very long hours of work, and when I find I have many tasks to complete I often come in at odd hours in the night, often as early as 2.00 a.m., and work for several hours in my office. I have to travel a lot and hence several of my days during the year are taken up in international travel as well. “Visionary and Pioneer of the Green Building Movement in India"“Visionary and Pioneer of the Green Building Movement in India" Questions with Green Leader: R K Pachauri 10
Dr. R K Pachauri Director General TERI. 5. Describe a project of yours, that has truly inspired you and why… The project that inspired me a great deal was what we launched at my Institute in 1995 as the project called Growth with Resource Enhancement of Environment and Nature (GREEN 2047). In this project we at TERI assessed what India has done in managing its natural resources in the first fifty years of independence i.e. from 1947 to 1997, and where we were likely to go by 2047. The results of this project were a major revelation. 8. Name any buildings and projects (modern or historic) which you regard as one the finest examples of green & sustainable design. TERI’s building known as RETREAT is a unique and pioneering example of green and sustainable design. It has been an inspiring example for many green buildings that have followed since its inauguration in the year 2000. 6. The funniest question someone asked you about “Green”? The funniest question someone asked me about green was whether painting buildings green would be environmentally friendly. 9. Describe your personality and passion. My personality and passion revolve around bringing about change in attitudes and actions of society, so that we restore our respect and reverence for nature in all human activities. 10. What are the critical elements, you believe, for India to become a world leader in the green building movement? I think the only way India can become a world leader in the green building movement is to create public awareness on the benefits that all of us would reap by moving in that direction. 7. What Dr.Pachauri does when has free time (away from the hectic world of architecture & TERI) ? I have very little free time, but I always find time to play cricket actively for a day on each weekend during the cricket season, and swim during the summer months every day I am in New Delhi. When I fly I work and if I have the time I write fiction. I have recently published a book called Return to Almora. Inspired to be GREEN thanks Dr.RK Pachauri, Director General TERI for his valuable time towards this inspiring interview with us. Inspired to be GREEN I January - February 2010 I 3
Green Construction with a Great Concept in Mind The TERI University Campus: Vasant Kunj On a plot of two acres, the 1000,000 sq ft university campus comprises an administrative block, an office block and a hostel block. The campus is aesthetically designed with several features of passive solar design, energy-efficiency and water and waste management systems. The genesis of TERI University is rooted in comprehensive research, consultancy, and outreach activities of TERI. The TERI University offersworld-classresearchfacilitiestostudents with its state-of-the-art infrastructure and well-equipped laboratories. Located at Vasant Kunj in South Delhi, the new TERI University campus has been planned to provide a setting that enhances learning and showcases the concept of modern green buildings. A hostel will also be part of the campus. The Building is designed by Mr.Sanjay Mohe (Architect) and executed by M/S CONFOSS CONSTRUCTIONS, E- 108, Lower Ground Floor, Greater Kailash Enlclave Part – I, New Delhi. Compiled by Mrs Milli Mazumdar & Mrs Priyanka Kochar.
The planning and orientation of spaces and building blocks ensures glare-free daylight in all regularly occupied areas. All the liner blocks are oriented in East-West direction with shorter facades facing the sun. The form of the building self shades the glazing such that direct sunlight is blocked at critical times of the day. The exposed facades and walls on the east and west directions have limited glazing. The shading devices are designed such that the windows are completely shaded during the summer, which also contributes to reduction in cooling energy demand of the building. Energyefficiency is furtherenhancedby insulation of the walls and roof; and use of high performance window glazing to minimize thermal gain. Orientation Green features • Insulation of external walls with rock wool. • Insulation on terrace done with vermiculite and puff insulation topped with China mosaic for efficient heat reflection. • Double insulation synergy azur glass is used in external facade with aluminum glazing. • Earth Air Tunnel, Thermal mass and VRV system for cooling the building. • Hunter Douglas louvers and pergolas are used in the building for controlling the intensity of incoming sun rays. • Solar water heating system. • Waste water recycling with STP. Inspired to be GREEN I January - February 2010 I 5
The predominant wind direction is taken into account in designing the open space. The hot air from outside moves into the central court where it passes over the water body and fountain. The air thus gets humidified and becomes cooler. This makes the central atrium area always cooler than the surrounding exterior. Use of efficient double glazing window units helps significantly reduce the heat gained through window glazing in the summers and the heat lost in the winters without compromising on the day lighting integration and the levels of visual comfort. The walls that are exposed to the harsh solar rays have a stone cladding which is fixed to the wall by channels. The air gap between the wall and the stone cladding by itself acts as an insulation layer. On the facades rock wool insulation is also provided in the wall. Energy efficiency is further proposed to be enhanced by insulation in the roof slab. Envelope-Design Section through the building To reduce the water demand, buildings in the campus have been provided with low flow fixtures such as dual flush toilets, low flow taps and sensor taps that would result in 25% savings in water use. Further, the wastewater generated from the hostel building equivalent to 8 KL/day will be treated through efficient biological process using a combination of microorganisms and bio-media filter. The treatment system requires low area and energy. The treated water meets the prescribed standards for landscape irrigation. Rainwater run-off from roof and the site would be used for recharge of aquifer. This would enhance the sustainable yield in areas where over-development has depleted the aquifer. Water Management Natural Ventilation
Cooling System The campus is equipped with three types of cooling systems, integrated to take advantage of different innovative technologies to achieve energy efficiency. They are discussed briefly as under. • Earth Air Tunnel (EAT) • Variable refrigerant volume systems (VRV) • Thermal storage Earth air tunnel system It is used for free cooling / heating of the building for a major part of the year. This technology uses the heat sink property of earth to maintain comfortable temperatures inside the building. Supplementary systems have been used for extreme conditions (monsoon). In such a system energy savings of nearly 50% compared to conventional system can be achieved. At the campus, this system is used for providing comfort for the rooms in hostel block. The VRV system is a modern air-conditioning system, similar to an efficient version of a split air conditioner. The VRV system is highly efficient under partial load conditions and therefore, has been used in areas with varying occupancies such as the office block, laboratories, administrative block and recreation & dining areas of the hostel block. It features customized control of individual zones. Depending on the cooling demands of the building, variable Thermal mass storage is used in the classrooms. It involves storing energy when available and using it when required. In the proposed arrangement, cooling of the thermal mass is done during night (when ambient temperatures are lower). During daytime when ambient temperature is high, the thermal storage is used as sink for the fresh air requirement. Estimated energy savings of up to 40% can be achieved with this system. refrigerant volumes circulate through the chillers. The VRV system also eliminates the requirement of a plant room; piping & ducting for chilled water; and contributes to 15% energy savings as compared to a conventional air conditioning system. Inspired to be GREEN I January - February 2010 I 7 Variable refrigerant volume systems (VRV) Thermal Mass Storage
Artificial Lighting The campus has an efficient artificial lighting system designed for minimizing the energy consumption without compromising the visual comfort in the building. The system takes advantage of day lighting wherever available. Efficient lamps with high lumen output fixed with mirror optics reflectors and bat-wing louvers for glare free uniform illumination have been installed. All fixtures have energy saving electronic ballasts. With efficient designing the lighting loads have been reduced from 2W/m2 to 1 W/m2. In areas where daylight is available, fixtures have been fitted with continuous dimming electronic ballasts. These fixtures are controlled by light sensors, which automatically dim the connected fixtures to achieve uniform illumination required for the task. In areas with non-uniform occupancy, Occupancy sensors that can turn off the lights when the space is unoccupied have been installed. This kind of sophisticated lighting system has a potential of saving 70% lighting energy demand. Day Lighting A View of Admin. Block Teri University Summary In an integrated scenario to achieve efficiency, all the above measures will contribute to 60% energy savings in comparison to a conventionally designed building. The water saving measures will have 25% reduction in the potable water use only by use of efficient fixtures. In addition, reuse of wastewater for irrigation purpose through resource and energy efficient biological process and rainwater harvesting for aquifer recharge would also contribute to efficient water management. Inspired to be GREEN is impressed by the sustainable design of the TERI university and is looking forward to more buildings designed in a very GREEN way.

In your Garden • Water the garden early in the morning or late in the evening. This reduces water loss due to evaporation. • Explore water efficient irrigation systems. Sprinkler irrigation and drip irrigation can be adapted to garden situations. • If you have little space in your garden, you could make a compost pit to turn organic waste from the kitchen and garden to soil enriching manure. • While shopping buy fruit and vegetables that are in season to help reduce enormous transport costs resulting from importing produce and, where possible, choose locally produced food. • When buying fish look out for a variety of non- endangered species and buy local fish if possible. At Renovation time • Make the renovations to incorporate green strategies like daylight and ventilation. • Chose low VOC paints and adhesives. • Use local and eco friendly materials & products. • Select water saving fixtures for your toilets and kitchen. • Use BEE rated equipment and appliances. • Recycle the waste generated from construction like scrap & packaging material. • Install CFC free air conditioning equipment with high energy rating. • Improve the building envelope system by installing insulation in roof and walls as well as select a high performance glass window with uPVC frame. At Home • Choose energy-efficient appliances and light bulbs. • Save water: some simple steps can go a long way in saving water like for e.g: you should always turn off the tap when you are brushing your teeth. And try to collect the water used to wash vegetables and salad to water your houseplants. • Let clothes dry naturally. • Keep lids on pans when cooking to prevent your cooker having to work extra hard • Prefer to use gas ovens, Geysers etc in place of the electric ones. • Recycle your paper, glass, plastics and other waste. • Use rechargeable batteries. • Send e-greetings instead of paper cards. At the Office • Use printers that can print on both sides of the paper; try to look into this option when replacing old printers. • Use the back of a draft or unwanted printout instead of notebooks. Even with a double-sided printer there is likely to be plenty of spare paper to use! • Always buy recycled paper - for your business stationery and to use in your printers. • Switch off computer monitors, printers and other equipment at the end of each day. Though in standby mode they're still using power - and that adds to global warming. • Always turn off your office light and computer monitor when you go out for lunch or to a meeting.. Going green is not only about living and working in a Green Building. There are so many ways to go green in your day to day life. If it is simple, fast and gives you the joy of showing your love & respect for our Mother Earth, then why not try these out. Make as many of these tips a part of your life and the environment and your friends will smile back! We need a Green Revolution to save the planet that gives us life.

GROW YOUR OXYGEN GROW YOUR OXYGEN Oxygen is the very essence of life! However, it is suggested that many of us have low levels of oxygen in our bodies. Over the last several thousand years it is estimated that the amount of oxygen in the air has fallen significantly and now stands at around 21%. However some cities around the world are recording levels of oxygen as low as 12%. At 7% human life can no longer exist. Why has it dropped so much? Simple - man is to blame. We pollute the air with carbon-based fuels and other chemicals and we are destroying our natural oxygen farms, the rain forests. This means more carbon dioxide and less oxygen throughout the world. Many people do not know their bodies are suffering from low oxygen and toxins caused by the effects of pollution and bad diets, but may not recognise the symptoms which include: low energy, interrupted sleeping patterns, frequent colds and infections, poor concentration and general poor health. • Stimulate brain activity • Increase memory capacity • Boost concentration • Develop stronger alertness • Raise energy levels • Improve strength • Build endurance • Detox your blood • Reduce stress • Calm anxiety • Alleviate tension headaches • Remedy irregular sleeping patterns • Help with cardiovascular activity • Prevent lactic acid build up • Strengthen the immune system • Revitalise the skin • Ease hangovers • A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four! • Over the course its life, a single tree can absorb one ton of carbon dioxide. • Trees help cool down the atmosphere. They can bring down your air conditioning costs by up to 20 percent. What can optimum level of oxygen can do to us?
Trees are our breathing partners. We may not live in a forest, but we need trees in order to live. People and animals depend on trees and plants for oxygen. As we breathe in, our body uses oxygen. As we breathe out, it gives off carbon dioxide. Trees do just the opposite. They take in Carbon Dioxide and then release oxygen (which also helps clean the air). Trees also help cool the Earth. Trees give off moisture. More moisture in the air means more rain and all living things need water. Trees cool the air by shading and through water evaporation. They act like huge pumps to cycle water up from the soil back into the air. The 200,000 leaves on a healthy 100 foot tree can take 11,000 gallons of water from the soil and breathe it into the air in a single growing season. Trees are a natural resource that can be renewed - by the planting of trees - replacing the trees that are harvested for use by people. We depend on forest products for things like the wood we burn for heat and the wood we use to make houses and furniture. We use trees for the paper to make books and letters we write. Actually, there are more than 5,000 things made from trees. Trees give us baseball bats, shoe polish, and even tooth paste that comes from tree extracts. Today, the people and companies that manage our nation's forests recognize that trees are a valuable resource and that it is in the best interest of each of us to conserve them. The idea of sustainable forestry means trying to keep things in balance - when trees are cut down to make paper and other products, new trees are planted or regrow naturally. Forests helps wildlife by providing them food and a home. Trees and forests help us by cleaning our air, soil, and water - and provide a place for you to camp and hike! So you can help the world by planting a tree. 1.

Why You Need to Live in a Green Home? Introduction "Home is where the heart is and a safe & pleasant place to be. Poor or rich, no children or a dozen children, adults have the control to make any place a good home.” The question that comes to mind, does “safe” only refer to protection from thieves and forces of nature? What about the home being safe for its occupants? Do you actually know the quality of the indoor environment you live in? Does “pleasant” only have to do with the design and interiors? Does it come at the cost of destroying nature and other species on the earth? What kind of world are we leaving for our future generations? Housing in India: It is our responsibility, as residents of India, to look beyond the old paradigm and look at our home, in a broader context and more responsible way. Our homes not only affect our lives, but affect the world around us. A simple step towards a more holistic lifestyle can have compounded effects on our environment. The population of our country has crossed the 1 billion mark and with the energy used by the residential sector is 22% of total energy consumption. A majority of this power comes from coal and oil; both having severe negative impact on the environment. With the economic growth, the housing sector growth has also flourished. The most critical issue is if this growth is sustainable and has a minimum negative impact on the environment. The domestic waste generated in our country which is sent to landfills is also staggering. We all generate waste, but in most countries, a majority of this waste is recycled or reused. Our lifestyle and awareness about the environment is lacking and hence these sustainable practices have not been implemented in majority of homes. We spend more than 85% of our life in an indoor environment and it is not uncommon to live in homes which have inadequate fresh air and ventilation. These are some of the many reasons why all homes to be built, should be designed and built in a sustainable manner. The Home & Its Occupants: Do you have any idea what a major impact the home can have on its occupants? A home can affect our physical as well as mental health. The design of a home can facilitate natural light and ventilation as well as provide a connection to the outdoors. Construction as well as selection of building materials is also critical to ensure no materials are selected, which have toxic effects on the occupant’s health. Countless studies have been done which prove the positive impact of fresh air and daylight can have on individuals. Research shows an improvement of up to 20% in productivity and well being of individuals who work and study in such indoor environment. Children learn better in schools which conform to these standards. Megapolis Pune
India has always been Green! Green Buildings and homes is not a new concept, the principles have been successfully done for centuries in the past. Our heritage buildings are great examples of truly sustainable buildings. The Taj Mahal, Red Fort, Hawa Mahal are great examples of buildings which followed these principles to the “T”. The green concepts were also used in residential buildings like the Havelis and courtyard homes. At a time where people did not have air conditioners and artificial lights, the designs had to utilize these free natural resources.Materialswerepredominantlyprocuredlocallyand the waste generated during construction was minimal. And it is such a joy and pleasure, to experience the breathtaking architecture and comfortable indoor environment in any of these buildings. We do not need to reinvent the wheel, we only have to recognize the knowledge and wisdom of our past and incorporate these in today’s context of lifestyle and construction requirements. What is a Green Home? “A green home incorporates smart design, technology, construction and maintenance elements to significantly lessen the negative impact of the home on the environment and improve the health of the people who live inside.” (US Green Building Council) A green home doesn’t cost much more than a regular design but it has a much better market value. Green Homes will approximately cost 3% to 5% more than conventional building constructions. The payback period for the higher investment is around 3 years and will be recovered through the energy & water savings. Benefits of Green Homes • Improved energy efficiency, between 20% to 50% energy savings over conventional homes • Increased water savings, around 30% to 50% • Toxin free materials & natural ventilation for better indoor air quality • Increased use of regional materials & products with recycled content • Promotes use of daylight for better health & productivity • CFC free equipment • Reduces/eliminates negative environmental impact • Improved asset value and marketability Tepeyac Haven Pasco, Washington LEED Gold Certified Taj Mahal Agra Salim Ji Ki Haveli Jaisalmer Hawa Mahal Jaipur Redfort Delhi Margarido House, North California LEED Platinum Certified Inspired to be GREEN I January - February 2010 I 15
Designing and building a green home is not a complicated process. The most important factor is the project team’s understanding and commitment to Green. The process of going Green involves the whole project team, i.e. the architect, landscape architect, HVAC, electrical, plumbing engineers, and contractor and for the most benefit, should start at the Conceptual design stage itself. IGBC Green Home Rating System TheIndianGreenBuildingCouncilwithover500committedmembers launched the first rating system for residential buildings in India. IGBC Green Homes is based on the LEED New Construction and LEEDHomesbuthas beenmodifiedtoreflectresidentialarchitecture and construction in India and our culture. National priorities are addressed in Green Homes, water and energy efficiency play a big role next to reduced use of fossil fuels and virgin materials, also handling of household waste and wellbeing of occupants is a criteria for a Green Home. Like in all LEED rating systems certification levels from certified over silver and gold up to platinum are achievable for projects which are reducing the negative environmental impacts. The Rating system consists of six categories and nine prerequisites. Credit Points can be earned under Site Selection and Planning, Water Efficiency, Energy Efficiency, Materials, Indoor Environmental Quality and Innovation & Design Process. The diagram illustrates the importance of each category, and shows that Energy and Water Efficiency together cover more than half of the total 80 Points. The potential of GreenHomesis amazing because75% to 80 % of the real estate demand comes from the residential sector. Developers like Mahindra Life-spaces and Aliens Group took the chance and came up with a completely new definition of residential buildings. These include climate appropriate design, building materials with recycled content, water saving fixtures, VOC free paints, and an energy saving building envelope additional to green areas which help create a healthy environment.

20 Simple Strategies to Go Green: Here are some of the strategies that make a home Green. You do not have to implement all of them but incorporating will make a difference to your operational costs as well as put a smile on Mother Earth’s face: 1. Sustainable Site • Retain at least 25% of the site as vegetated open space • Provide electric charging stations to encourage alternative fuel vehicle • Use a light color (painted or light tiles) to reflect heat away • Chose a site which is close to basic amenities like ATM, shops, schools etc 2. Water Efficiency • Select water conserving fixtures like water closets, faucets and showers • Reduce the amount of turf in the landscape, use native ground covers • Implement a rainwater harvesting plan for all roof run-off water • Install water meters to understand and gauge your consumption 3. Energy Efficiency • Improve building envelope performance by choosing appropriate glass, wall and roof • Install solar hot water heating system • Use efficient lighting technologies and fixtures like CFL’s and LED’s • Use BEE star rated equipment and appliances like air conditioners, refrigerators etc 4. Materials and Resources • Separate waste into recyclables like paper, plastic, metal and glass at source • Specify materials with high recycled content like AAC blocks, glass and steel • Procure materials locally (within 500 kilometres) • Reuse salvaged and refurbished materials / products when possible 5. Indoor Environmental Quality • Architectural design to provide adequate daylight and views for all spaces • Use LOW VOC (volatile organic compounds) paints, adhesives, sealants and carpets • Utilize natural ventilation when possible and design to accommodate cross ventilation • Perform building “flush out” before occupancy, to remove construction contaminants. The process of going Green is of course, much simpler and easy to implement in a new construction than in an existing home. From the above checklist, existing homes can implement these during renovation. Conclusion: Green homes are, simply put, better homes. Homes built to these standards are energy & water saving, provide its occupants with an indoor environment which positively affect their health, reduce the impact on the nature and most importantly show our commitment and concern for our future generations.

Designing Homes with Adequate Natural Ventilation & Daylight Designing Homes with Adequate Natural Ventilation & Daylight We all know that a good home should provide an indoor environment for occupants with adequate natural ventilation and daylight. “More easily said than done” is a statement that holds true when you have analyzed some of the homes in our cities and realize that and these basic requirements have not been satisfied in all cases. Have you ever noticed the abundance of fresh air and daylight in any historic building or home? These were spaces which did not have air conditioning or artificial lights, and hence attention was paid to utilizing free natural resources. These buildings combined the use of materials, innovative technologies and understanding comfort related issues in buildings. The fact that these buildings are still functioning and pleasing to the eye is testament to the greatness of our heritage and wisdom. Designers today, tend to overlook this challenge, only to hide the deficiencies in the built environment through artificial means. The role of an architect, is far greater than the designer of an aesthetically pleasing elevation and functional plan, and also includes understanding the comfort of occupants. Natural ventilation and daylight have been proven through countless studies to improve health, productivity and overall well-being of the occupants. So does your home meet these minimum standards or do you need to rethink the environment you spend a majority of your life! Windows: Daylight vs. Heat Gain Daylight (which we have abundance of in India) needs to be carefully managed and dealt with in the design of buildings. While the light from the sun is critically important, the heat needs to be controlled. How often have we seen glass box buildings, which have more glare than light, resulting in curtains and blinds being closed and artificial lights burning through the day. The windows are responsible for bringing in light and heat and hence the design should address both issues. The R value (resistance to heat transfer) of a window (high performance) is about 1/4th of a opaque wall, hence the placement, performance, size and shading are critical. • North or South orientations preferred • Appropriate shading for all windows • Specifications of VLT (visible light transmittance), Solar Factor / SHGC and U value • Windows between 2’6-7’6” contribute to views, above 7’6” are for daylight only • Frame – uPVC are most energy efficient • Light shelves for spaces of larger depths Glazing Factor = WindowArea [SF] Floor Area [SF] x ( VLT x Constant) Constant Values: Windows on wall : 0.2 Skylight : 1.0 Another rule of thumb is that light will penetrate 1.5 times the height of the window and hence for larger floor plates, courtyards can be introduced based on this calculation. A simple rule of thumb to achieve daylight is to achieve 2% with formula below:
Natural Ventilation: The movement of air from the outside and through a space is termed as ventilation. Ventilation is critical to replenish the oxygen and remove contaminants in a space. A common issue known as “Sick Building Syndrome” is observed in building with inadequate fresh air being supplied and the spread of germs and a general uncomfortable feeling is experienced by the occupants. Many designs claim ventilation by providing a window per space. This is incorrect, as for air to flow, there needs to be an inlet & outlet for air and some type of convective or pressure system. This is evident in any traditional home design incorporating courtyards. The courtyard is a store for cool air and windows open into the court. Equally important are the high level ventilators on the opposite side of the room, which when vented, create a negative pressure in the space, whereby drawing in the cool air from the courtyard. While designing homes, a simple rule of thumb for fenestration to achieve adequate natural ventilation is as follows: Please note that this refers to “openable area” and hence the type of window is critical – sliders allow only 50% operable and should be calculated. Space Type Openable areas as a percentage of total carpet area Living Spaces 13% Kitchens 10.5% Bathrooms 5% Conclusion: A healthy and productive indoor environment is the result of careful and intelligent design. A design incorporating natural daylight and natural ventilation would certainly not cost anything more and the benefits are both monetary and intangible. Buildings are made to keep us safe, happy and healthy. It’s up to us to demand this from our architects, MEP, building material & product manufacturers and the design & construction industry.

Author: Mr. Abhay Desai Director Marketing South Asia. HEALTHY HIGH PERFORMANCE CLEANING A pathway to Sustainable Cleaning Clean is just the beginning Just imagine where we would be today without the means to remove harmful and unwanted contaminants from our buildings. Contaminants like bacteria, viruses, molds and fungi can adversely affect human health. Common dirt dust and soils can be contaminated with pesticides and other chemicals. Poor indoor quality is often associated with improper cleaning products and procedures. Aside from the obvious impact on health issues (respiratory illnesses, allergies, headaches etc) the cleaning products and procedures can also impact an organization financial bottom line. Without a doubt cleaning is important to protect our health as well as the buildings in which we live and work. Also Users of cleaning products are increasingly aware of the need to conduct cleaning operations in a way that is ‘environmentally friendly’. But this doesn’t just mean using chemicals that are safe for the environment, it means minimizing all the many other environmental impacts that arise in making and using cleaning products, such as energy consumption and waste disposal. The term ‘improving sustainability’ is used to refer to making an improvement in the overall impact of cleaning. There are three key steps, which are required to optimize sustainability: • Choose products that are designed for sustainability as well as safety. • Work with suppliers so that they responsibly manage their manufacturing impacts. • Minimise the environmental impacts that arise during your cleaning operations. Step 1: Choose products that are designed for sustainability as well as safety. a) Require your vendor to declare the list of banned ingredients. b) Ensure that the manufacturer produces enough evidence of the fact that the ingredients are selected not just for safety but optimize sustainability of the finished product when used diligently. Step 2 Work with vendors so that they responsibly manage their manufacturing impacts. a) Ask your vendor for evidence that they have effective control of impacts during the manufacturing phase. Key areas include: • Minimising raw material and finished product wastage during manufacture. • Minimising consumption of energy and water. • Minimising emissions to sewer and atmosphere and, in particular, controlling emissions of hazardous substances to avoid risk to people or the environment. • Minimising packaging waste and recycling used packaging. • Operating an Environmental Management System. • Operating procedures to prevent accidental emissions. • Operating Occupational Health & Safety systems to protect staff. Step 3 Minimise the environmental impacts that arise during your cleaning operations. How? • Define what task the cleaning products will be used for and buy products which deliver the required performance. • Analyse and reduce rework rates. First time cleaning is essential to minimise waste, particularly in energy intensive operations such as machine dishwashing. • Favour more concentrated products, where applicable. • Dilute and use products according to the manufacturer’s instructions using accurate dosing systems where appropriate. • Service cleaning equipment regularly, particularly critical items such as dosing pumps for automated machines. • Train staff, for example using BICSc courses which detail out the way we handle cleaning chemicals. Smart building owners and managers in organizations from across all sectors and industries are taking actions to reduce the negative impact of s of their facilities. Healthy High Performance Cleaning programs are designed to improve a buildings environmental quality and sustainability with a cost neutral or cost reduction impact on operations. It is a unique, all inclusive approach to cleaning that helps ensure a clean and safe work environment, increase employee productivity and satisfaction and enhance the value and integrity of buildings while reflecting organizational mission and values. The HHPC program starts with environmentally preferable chemicals then offers proven cleaning strategies, procedures and purchasing guidelines for consumables, tools and cleaning Equipment. With a HHPC program you get: 1. A clear perspective on the need for green cleaning and green cleaning concepts. 2. Cleaning strategies procedures and guidelines backed by the most up to date training support tools. 3. Environmentally preferable janitorial guidelines for chemicals, paper tools and cleaning equipment. 4. A pathway to earn credits towards certification under the LEED for existing buildings Green building Rating system The Healthy High Performance Cleaning takes traditional cleaning beyond appearances with procedures designed to make your building the safest, healthiest, and the cleanest it has ever been. The most important step is to understand that cleaning plays a huge role in the health of the buildings occupants. Cleaning also directly affects the asset value of the building. The end goal of the HHPC program is to simplify the lives of customers by providing more than environmentally preferable cleaning products and helping them achieve safe, healthy, high productivity facilities.
Ground Source heat pumps In contrast, the Geo-Thermal Heat Pump uses the same type of compressorized refrigeration system to remove heat from the building, but it transfers the heat into the temperate earth and not into hot air. Because it is easier to move heat to the cooler earth than into the sweltering summer air, Geo-Thermal Heat Pumps do not have to work as hard to cool your home. This efficiency has a bottom line - substantial savings reflected in your monthly utility bill. When heating, the compressor system of the Geo-Thermal Heat Pump uses the heat energy stored in the earth to efficiently heat your home while other heat pump systems are laboring to gather heat from the frigid outdoor air, or are even freezing up. Because Geo-Thermal Heat Pumps utilize such a large amount of the earth’s stored energy, they are typically more efficient than even heaters which burn environmentally damaging fossil fuels. Geo-Thermal wonder works by taking advantage of the near constant temperature of the earth which exists only a few feet below the surface. For example, when cooling, air- to-air heat pumps and other air conditioning units found in most homes actually remove heat from the air in the building through their compressorized refrigeration mechanisms and move the heat to the outdoors where they attempt to expel it into the air. As summer progresses and the average daytime temperatures raise, these other units find it more difficult to expel this heat into hot air- the system actually loses efficiency and labors to keep up with cooling demands.

Green Personality of the Month: Frank Costanzo Mr.Frank Costanzo Director/ Consultant Peerless Green Initiatives, Chennai A deep Green Interview...A deep Green Interview... Can you tell us about your background and what made you give up the practice of law to be a green consultant? Well, because of my background, I like to think that I bring a unique skill set to the eco-consultant facilitation marketplace. I’m also amazed how the blessings of life have worked out so poetically in my case. When I was in college and law school I was extremely active in the budding green movement. Then I graduated and-like many of my lawyer peers- you chase the position that offers the best benefits. Unfortunately, commercial insurance litigation firms won over green-advocacy. (Laugh) However, it couldn’t be more perfect because for fifteen years I assembled all the skill sets necessary to become an ‘all round’ consultant and facilitator. As a litigation attorney, your stock and trade is your ability to deeply and fully find and analyse every factor that can influence a case one way or the other. You also have to get inside your opponent’s head and you have to know every detail of your client’s business. Many of my peers would interview clients in their air conditioned offices and soft leather chairs...not me. I came from a business background...my great- grandfatherstarted a hardware store that still operates today. For me, there’s nothing like understanding someone’s operations by studying it -first-hand- in the field. So, I’d frequently be found wearing a hardhat on construction-sites, spending long nights with Madras IIT techs doing copywrite forensics for Mumbai-based BPO platforms, or wearing hip waders for a due diligence for commercial fishing vessel. The advantage it gave me when it came time to stand-and- deliver in front of a judge or jury was immense. So when I achieved the freedom to choose my career path, I let my heart lead and brain follow. I harmonized my international legal, business and economic background with my passion for the green movement. I also utilized my deep network of experts in India and U.S. to build my consultant ‘dream team.’ The benefit of my experience is that I know how big and small businesses think. Plus we’ve finally arrived in an age where ‘going-green’ makes business sense beyond CSR (corporate sustainability and responsibility). It’s unfortunate that we need to think that way, but the reality is that businesses (by and large) only start thinking CSR when their bottom lines are fat or if they have an image they need to protect. So now we in the green industry have the distinct advantage of offering solutions that allow businesses to fatten their bottom lines regardless of their dedication to sustainability. I guess that’s another advantage of being a former lawyer with a business background- you become very practical and economic minded in your approach.

The PGI mission ethos is two-fold in that it consults and is an advisory; and it is also a network portal that creates and facilitates project and business plans to fruition. PGI also is adept at creating and securing strategic relationships -tie ups- domestically and internationally, between privates, NGO’s and public- private partnerships. At PGI, we’re skilled at vertical integration of process and can offer end-to-end solutions that can really impact the research, development or supply of new green technology, materials and processes. We’re all pleased with the economic ties that our respective countries are establishing. It’s very encouraging for the green industry as well as combating global warming, which obviously knows no political borders. When a group from Madras IT won the New York ‘Next Big Idea’ award, that made us at PGI very excited and inspired to continue pushing the envelope of green business development. What is the scope of PGI’s range of services? We focus on four areas: energy, sustainable building, responsible agricultural practices, and ‘green’ certifications (LEED, WFTO, FLO, Organic to name a few.) Then we have two sub-sectors: support of rural primary education and environmental crisis management. We couple that with creating and negotiating domestic and cross-border U.S.-India strategic alliances for the best development and use of the state-of –the-art; funding core missions through public private partnerships and NGO’s and so on. What I can say philosophically, regarding PGI’s ethos, is that we use our wide reach network to be a force multiplier for clients. To use the sourcing vernacular... our core group has extensive vertical penetration along a wide horizontal spectrum. Translation please? Ha...yes,ok. Wellwehaveasourcoresomeofthefinest in the industry in areas including LEED architecture/ engineering/construction, energy R&D techs, organic horticulturists, conservationists and IT engineers. Our sciences-set is what makes us ‘peerless.’ We overlay that with top-shelf professionals in business, vertical integration, supply-lining, trade practices, law, economics, licensure, government relations/ lobbying and media. That set is what makes us able to facilitate tie-ups and projects. That’s the ‘initiative’ aspect of what we do. So you live and work in India? Yes, and I love it. Before starting Peerless Green Initiatives (PGI) I was general counsel to many U.S. companies with interests in India and I was enamoured with the development of India as an up- and-coming economic power. Also some of my closet colleagues were Indians and NRI’s and I really cliqued with their balanced business mindset. The best thing about getting into the green movement in India is that it doesn’t come with a lot of the other baggage that exists in certain sectors. Media and politics worry about border threats, business sector worry about outcompeting China...but the green-set flies above all that, and with the growing amount of Government incentives and great institutions like the India Green Building Counsel, we’re witnessing a period of innovation that makes every other Indian sector envious. (Laughing) It true...I mean, in the U.S. the government has been providing massive incentives for promotion and innovative of green business models, and I’m pleased to see the Indian Government, particularly in Tamil Nadu, has joined in introducing strong incentives for the development of green non-grid-dependent solutions for the burgeoning energy building and agricultural demands. Economic scientists like Steven Levitt and Stephen Dubner have shown that people respond strongly to strong incentives. Those incentives, for example LEED, World Fair Trade and Fair Trade Labelling fuel the engine of green innovative development. Inspired to be GREEN I January - February 2010 I 29
I could fill a volume with all the India economic forecast data in my head. But it suffices to say ‘going green’ is not a luxury- its mandatory if India is to continue its current trajectory. It’s a well quoted fact that 6% of India’s grid potential comes from wind energy, but only 1.5% is being utilized...reason being that all the incentives were put into facilitating erection of turbines but not for their on-going operation. That’s where PGI focuses. Building relationships, alliances and using its lobby arm to balance the benefits. We’re very holistic in our project approach and it pays dividends for our clients and the industry as a whole. What do you see as the industry’s; your company’s greatest challenge? I think we’re facing the same challenge as the rest of the industry....how to distribute the concept of using eco-sustainable alternatives in sectors accustom to conventional ways and means... sectors that are often addicted to non-renewables, fossil-fuel and grid dependency. It disturbs me to see these massive 1000+ unit development plans for North Chennai with no CSR plan in mind. We have to enlighten that sector that incorporating LEED principles at the planning stage is vital to the region’s survival...literally. They should put as much analysis in sustainable building factors as they do determining whether the building foundation is on solid footing. What advice would you give to green business owners and start-ups? Those starting ventures or growing existing ventures need to have a solid business-plan but when the calculations lead to questions of risk, the unavoidable fact is that is the cost of being a pioneer... of being entrepreneurial. I gave a lecture at Kodai International School and I used the example of Henry Ford (who by the way planned his model T to run on corn alcohol) who failed three times before starting his successful brand. The students were shocked and we had a lively discussion regarding the value of failure. Being unafraid of failure, and seeing failure as an opportunity for future modification and success, changes one’s risk tolerance and their perceptions about risk. I know I’m sounding like I’m a mix of Donald Trump and J. Krishnamurti, but you know, I read Krishnamurti’s compendium ‘On Fear’ probably ten times through my life and you find that it applies so easily to business that I credit much of PGI’s meteoric success to his vision. My personal value-added to consulting venture start- ups is that I’ve represented 1000’s of businesses as a lawyer and you end up ‘living’ their successes as well as learning what mistakes they’ve made. I have immense first-hand knowledge regarding suitable strategies and where the snares may lie. So to those business owners I say that these are exciting times we are living. Never in the history of Man have the stakes been so high, and never has mankind had to change its habits and infra-structure more dramatically. If you’re not willing to be part of it, you’re in trouble, because the ‘risk analysis’ of not being part of it is fatal. Literally. I think I have a right to comment because I’m an American who loves living in American and I decided that I could make the difference I want by being maverick and having my boots-on-the-ground here in India. And I love the experience of consulting here. I’m pleased to say that I’ve had more than a few hesitant clients –in India and US- who I’ve helped ‘see the light’ and exercise their spirit of entrepreneurialism effectively, and now they enjoy life at the helm of healthy companies or tied in fruitful US-India relationships. Let me finish this interview by thanking Inspired to be Green for this opportunity and it providing the industry with such a quality and timely periodical. It’s a great source of information, insight and a terrific forum. Mr.Frank Costanzo PEERLESS GREEN INITIATIVES www.peerlessgreen.net frank@peerlessgreen.net

GREEN BUILDING CONSULTANCY by Mr.Rumi Engineer, DGM, Godrej & Boyce. Growth is necessary for development of individual and nation as a whole. India’s growth rate is pegged at modest 8% . Construction Industry has significant contribution in India’s GDP. There are modern day evils associated with developmental measures adapted today. Development should adapt sustainable measures and Focus on Environmental benign impacts. Hence whenever one thinks of constructing/ renovating a building… Think green. Why Green …. Green is an iconic word for sustainability. sustainability encompasses features like site , water, energy, materials and indoor environmental quality IGBC has been spearheading the movement since past couple of years. Myth #1 : Green Buildings are costly..? Incremental cost solely depends on project’s baseline cost. Now a days in competitive environment the baseline has improved considerably with respect to the past hence incremental cost is marginal. Green building is not a Cost but an Investment which pays back in form of rich dividends to all the stake holders year on year. Myth #2 : Green Buildings result in time overruns..? Normally a construction project of 10 Lac sq.ft built up area, takes 2 years minimum or more to complete. There is no activity in the green building certification which will span more than the project completion time lines. All the activity runs parallel to the project activities. There is absolutely no chance of project time lines getting impacted. Myth #3 : Green Buildings … lots of documentation..? Documentation by way of drawings, calculations and technical submittals is anyway done for all the projects. Same documentation is compiled and collated in a structured manner which benefits the project’s design team and facility staff who operates the building. Benefits of going in for a Green Building • Win-Win situation for all the stake holders. • Energy & water savings features considered and built in right from the design. • Measurement and verification of the energy & water consumption in the building. • Measurement & verification will bring in the accountability and help in optimization of resource use and result in cost control. • Goodambience(internal&external)fortheoccupier. • Waste management & recycling of materials helps reduction in pollution and burden on landfill.
Godrej Green Building Consultancy renders services in three different areas. 1. Facilitation. 2. Energy & Lighting simulation. 3. Fundamental and enhanced commissioning. Facilitation : Facilitator is an anchor to the project team guiding them through entire journey of certification process. • Conduct training for the team members to understand the gamut of documentation. • Review the status of documentation. • Sharing wealth of information for sourcing of vendors, materials. • Evaluation & promotion of new technologies. • Review the documentation prior to submission. • Interpret the review by the assessor and explain to project team. Energy & Lighting Simulation : Prior to freezing up of designs, materials and equipment specs, simulating the building design on the software goes a long way in helping the designer to make judicious decision. Similar exercise can be taken up for lighting design. Day light consideration with glare control is very important aspect in the lighting design. Simulation facilitates the designers by displaying virtual images of the interiors to gauge the situation which will be prevalent after construction. For commercial green buildings it is mandatory to meet the ASHRAE 90.1.2007. In Cores & Shell project it is mandatory to demonstrate 14% saving over and above the ASHRAE 90.1.2007 benchmark. Chunk of Investment in a building is attributed to 1. Glazing : High performance double glazed unit assembly 2. Roof Insulation : Overdeck roof insulation 3. HVAC : High efficiency chillers, pumps, motors, drives, heat recovery wheels 4. Indoor air quality : CO2 Sensors, demand control ventilation To optimize on the CAPEX one needs to have best mix & match of the above measures mentioned above. In absence of energy & lighting simulation exercise, it is virtually not possible to arrive at best efficiency measure suitable for the project. Inspired to be GREEN I January - February 2010 I 33
Fundamental & Enhanced Commissioning Building design has world class architectural features, robust and versatile HVAC design, selection of Hi-Eff. equipments etc. Will the building systems operate as intended and results in the savings..? The answer is emphatic NO ! In any building be it green or non-green the systems in the building have sub-systems which are interactive with each other. This complicates the matter hence one requires to test and integrate the systems. Fundamental commissioning commences right from the design stage, continues through the construction stage and ends with the project completion. Design stage is very critical to understand the projects requirement and also work jointly with the MEP consultants to optimize the Capex. Even operation and maintenance cost has to be given due consideration during design stage itself. Verifying of system performance at site and co-relating with the design is known as Testing and Commissioning (T & C) of systems. There are different type of T & C performed, some may be sampling and other could be 100% comprehensive. Preparation of system manual and training to facility staff is one of the important feature of fundamental commissioning. Enhanced Commissioning : After completion of project, post occupancy this period is very critical in any project. The project team hands over the systems to facility staff, smooth transition is what one looks for. Commissioning agent facilitates the process and carries on with the review of the operations of the system and also help resolve the pending issues in the project. Measurement & Verification Proof of the pudding is in eating! One cannot improve till one measures one’s performance, keeping in mind this adage, measurement and verification is like having display panel in the car. Imagine driving a car without the display panel. No indication of how much fuel is left, what is the oil level, engine temperature and what speed are we driving etc. With all the herculean efforts put in through out the journey at end if one does not have robust monitoring system in place how can one gauge the benefit derived from all the initiatives taken up for energy and water optimization. Commissioning, measurement & verification is very critical to all the building be it green or conventional. Energy simulation, commissioning, measurement & verification are a must for all the buildings to realize the potential of energy and water saving. In a building Operational and Maintenance (O & M) cost outweigh the capital investment. The analogy is of iceberg. Cap (30%) of iceberg is the CAPEX and the base, which one cannot fathom underneath (70%) is the operations and maintenance cost. A modest Target of 10% Saving in Operation & Maintenance Costs will outweigh the 20% saving in the Capex.
VisitattheConstro2009 A really green home at the showground All visitors could see how simple green principles are implemented. Compressed paper boards were used for the ceiling, Bamboo was prominently used as furniture and green walls formed an attractive indoor space. The exhibitors showcased their products and could feature their systems better than at a “conventional” exhibition. The ‘Eco-Friendly Model Home’ is a compilation and assembly of various ‘green materials’ like recycled plywood, energy savings paints, UPVC windows, to name a few. Around and outside the Model Home, there was a display of numerous materials. A film on application of eco-friendly materials and methods was run at intervals inside the model home. Usually professionals are aware of the need to use green; however, the actual system of using it, right from identification and sourcing the material to the execution and inter-linkage of the technologies is a matter of detailing which is non –standard. This essentially means that there is a gap between the awareness of the principles and the need, to the actual usage of the materials and technology at professional level. In addition, there is a need to educate the common man, the client, the customer, the buyer and the end-user. Many a times, this role of an educator falls upon the designer, the architect or builder. While the desire to be and design green is present, one is usually unable to translate into reality due to incomplete knowledge. It was expected that the Eco-friendly Model Home present in Constro along with the stalls for the materials and technology providers was covering required aspects completely. While the actual house demonstrated the usage, the looks, the inter-linkage etc, the details as regards pricing, availability and other administrative aspects were available in the stalls. One could obtain end-to-end information for actual design and execution of the ‘Eco-friendly Model Home’.

As bamboo is a very “green”, rapidly renewable and versatile building material – the Contro in Pune showcased also a “Bamboo-House”. TheBamboohousewasclearinganymisconceptions about bamboo and perceived limited usages! In fact, it should inspire many a visitor to actually use bamboo in their projects. Since ‘seeing is believing’, this attempt to create a structure in bamboo got sceptics to rethink! Additional information and guidance about bamboo was available from the personnelatthestallfor‘NationalBambooMission’ thus, one obtained end-to-end information for actual execution of bamboo usage. How Green is Bamboo? • Bamboo is not a tree – it’s a grass, and it grows like one, many species of bamboo can grow two feet or more a day. • When it’s harvested, it need not be replanted, because it will grow a new shoot from its extensive roots system. • Bamboo renews itself readily, unlike hardwood trees, which once cut, are gone forever. • Bamboo is an endlessly renewable resource. • Bamboo is a viable replacement for wood. It is one of the strongest building materials, with a tensile that rivals steel and weight-to-strength ratio surpassing that of graphite. • Bamboo is a critical element in the balance of oxygen and carbon dioxide in the atmosphere. • It helps reduce the carbon dioxide gases blamed for global warming. • Somebambooevensequestersupto12tonsofcarbon dioxide from the air per hectare, which makes it an extremely efficient replenisher of fresh air. • Bamboo plays an important role in construction industrybecauseofitsversatilityandappropriateness for affordable housing in India. • Potential of Bamboo as construction material has been already explored, experimented and implemented by designers, engineers, and institutions like KONBAC, National Bamboo Mission and INBAR to name a few.

With COFFOR stay-in-place formwork technology, eco- friendly construction is possible without compromising on TIME, QUALITY and COST of construction. Its an eco-friendly company, making "green" products. Their product is "eco-friendly" because it allows the use of various "green" filler materials, i.e. laterite, clay, ash, which reduces the use of concrete for GF and GF +1 structure. Depletion of natural resources is reduced, as less wood is used compared to conventional structures and also much less water compared to brick masonry. Use of brick is decreased/eliminated, reducing the amount of natural resources and energy used to make them. The use of oils to clean metal sheeting is eliminated. Transportation is reduced (saving Gasoline) as COFFOR panel can be folded flat for shipment. This uses far less space than brick trucks. For example, 1 house can be constructed in 1 container of COFFOR panel, as opposed to almost 5 trucks of brick. The company manufactures locally, eliminating need for international shipments. Coffor's operating practices are also eco-friendly, for example, 1 tree was planted for every 1000sq.ft. of developed landscape area for their latest project. A new way to build GREEN an Innovation seen at CONSTRO Small wind turbine, solar streetlight, roof garden & vertical garden Reuse of glass bottles for lighting Constro 2009 in Pune Pune organized by Pune ConstructionEngineeringResearchFoundation(PCERF). inspired more people in the construction community to go green and we are excited to see also more exhibitions turning towards green. Thanks to Mr.K.P.Baney (President - Constro 2009), Mr.J.P.Shroff (Chairman of Constro 2009), Mr.S.S.Nivasarkar, Chairman of Bamboo House Committee, Mr.K.B.Chaphalkar (President of Association of Civil Engineers India) and the whole committee for this lovely exhibition and the information.

LITTER FREE AUROVILLE LITTER FREE AUROVILLE Collective Waste ManagementCollective Waste Management Welcome to...Welcome to... The LFA campaign is an initiative of Soma Waste Management, Auroville, in collaboration with Eco Service and many volunteers from Auroville - to be more precise: over 1800 people participated in the days activities, significantly higher than the organizer expected! LFA wants to make all of us aware of our waste-generating behaviour and of the need to upscale waste management in Auroville. Its an extraordinary event which took place in Auroville, the town project aiming at human unity as envisioned by Sri Aurobindo and The Mother. 25 teams of children from twelve schools, of employers and employees, and of residents and guests were single-mindedly involved in a sweeping clean-up action, clearing roads and roadsides of carelessly discarded litter throughout the city and its immediate environment. “That’s not all”, says Ribhu, one of the young coordinators of LFA, the “Litter-free Auroville” campaign. “We heaped up the collected garbage and demonstrate its segregation and sorting, to ensure that most of it can later be recycled. We had an interactive exhibition with games, puppet shows, quizzes, pledges, and lots of information on global and local pollution and on composting and recycling.” The Litter Free Auroville Concept
The Strategy behind Litter Free Auroville: Goals 1. Waste avoidance and reduction. 2. Pollution free environment. These are high aspirations and long term goals, but we felt that all initiatives should be steps forward towards achieving these goals. Objectives • Awareness: To promote and create awareness on positive waste disposal practices and the impacts of waste on the environment (air, water, soil). • Actual waste clean-up: To have the highest community participation in AV to date in collecting litter in half a day in AV. Create aplatform for change:To createan interactiveplatform for the exchange and dissemination of ideas and advocacy of best practices. Develop ideas and translate them into action which would be a step towards reaching our goals. • It is very much an objective of this campaign so I strongly felt it should be included with the other two.

Inspired to Be Green Journal: January 2010

  • 1. inspiredtobe forthoseinspiredbygreen,writtenbytheexpertsingreen Free Publication January - February 2010 Dear Inspired Reader, I am very happy to introduce myself in the first issue of 2010. Mr Kishore Kumar, Owner of Inspired to be Green Magazine, gave me the great opportunity to manage the green magazine from now on. Together with the team of Inspired to be Green we are building the platform for India’s Green Building community. Since I came the first time to India, I am fascinated from this country. Every day is full of learning experiences, challenges, lovely people and excitement. Born in the heart of Europe, Austria is one of the most advanced countries for energy efficient buildings and technologies. I graduated from there as an engineer for eco-energy and energy efficient buildings. Maybe it was just not challenging enough to design another net-zero or solar passive building in Austria or maybe it is just the open minded people in India who convinced me to be part of India’s Green Building Movement. In India I worked on solar airconditioning, energy-efficiency improvement for hotels, as well as on energy modeling and LEED/IGBC projects during my time with Spectral Consultants. To be a LEED accredited professional and certified for energy and quality-management from the TUEV Germany gives me a good understanding of the process involved in an energy-efficient building design. I love to see so many new ideas and green projects coming up in India, and to get to know the people behind these great projects and companies is a wonderful work. I know that we have everything required to make the green building movement to a success: expertise, innovative product manufacturers and builders who are ready to take up new ideas. Sharing our knowledge and experience will help us in the future to make buildings more energy-efficient and ecological. I will work with passion, and a lot of motivation for Inspired to be Green – and I hope you will support our initiative. Stay inspired, Isabelle

  • 4. Dr. R K Pachauri, Director General TERI 1. What inspired you to take up “the journey on the path of green”? What inspired me to take up the journey on the path of green stems from two factors.Firstly,IwasbornandspentagoodpartofmychildhoodinNainitaland in the beautiful surroundings of mountains nestling a large and placid lake. Extended exposure to the beauty of nature at such an early stage of my life left a deep impression on my sensibility related to green issues. The second reason lies in the fact that when I became a researcher I initially worked on energy issues and realized very soon the major environmental implications of the entire energy cycle, including the accumulation of greenhouse gases, which have led to human induced climate change. 2. In what profession or on what project were you working 10 years ago? Ten years ago too I was Director General of The Energy and Resources Institute (TERI) and essentially involved in building up this Institute. At that stage I was also the Vice-Chairman of the Intergovernmental Panel on Climate Change (IPCC), and played a significant role in several activities related to the preparation of the Third Assessment Report (TAR). In those days I also had time to carry out some research myself which unfortunately has become increasingly difficult now. 3. What is true sustainability in your view? In my opinion true sustainability is based on a practical understanding and application of the very simple definition in the Brundtland Commission report which essentially defines sustainable development as that form of development which meets the needs of the present generation without compromising on the ability of future generations to meet their own needs. 4. What does a day in the life of Dr.Pachauri look like? My life involves very long hours of work, and when I find I have many tasks to complete I often come in at odd hours in the night, often as early as 2.00 a.m., and work for several hours in my office. I have to travel a lot and hence several of my days during the year are taken up in international travel as well. “Visionary and Pioneer of the Green Building Movement in India"“Visionary and Pioneer of the Green Building Movement in India" Questions with Green Leader: R K Pachauri 10
  • 5. Dr. R K Pachauri Director General TERI. 5. Describe a project of yours, that has truly inspired you and why… The project that inspired me a great deal was what we launched at my Institute in 1995 as the project called Growth with Resource Enhancement of Environment and Nature (GREEN 2047). In this project we at TERI assessed what India has done in managing its natural resources in the first fifty years of independence i.e. from 1947 to 1997, and where we were likely to go by 2047. The results of this project were a major revelation. 8. Name any buildings and projects (modern or historic) which you regard as one the finest examples of green & sustainable design. TERI’s building known as RETREAT is a unique and pioneering example of green and sustainable design. It has been an inspiring example for many green buildings that have followed since its inauguration in the year 2000. 6. The funniest question someone asked you about “Green”? The funniest question someone asked me about green was whether painting buildings green would be environmentally friendly. 9. Describe your personality and passion. My personality and passion revolve around bringing about change in attitudes and actions of society, so that we restore our respect and reverence for nature in all human activities. 10. What are the critical elements, you believe, for India to become a world leader in the green building movement? I think the only way India can become a world leader in the green building movement is to create public awareness on the benefits that all of us would reap by moving in that direction. 7. What Dr.Pachauri does when has free time (away from the hectic world of architecture & TERI) ? I have very little free time, but I always find time to play cricket actively for a day on each weekend during the cricket season, and swim during the summer months every day I am in New Delhi. When I fly I work and if I have the time I write fiction. I have recently published a book called Return to Almora. Inspired to be GREEN thanks Dr.RK Pachauri, Director General TERI for his valuable time towards this inspiring interview with us. Inspired to be GREEN I January - February 2010 I 3
  • 6. Green Construction with a Great Concept in Mind The TERI University Campus: Vasant Kunj On a plot of two acres, the 1000,000 sq ft university campus comprises an administrative block, an office block and a hostel block. The campus is aesthetically designed with several features of passive solar design, energy-efficiency and water and waste management systems. The genesis of TERI University is rooted in comprehensive research, consultancy, and outreach activities of TERI. The TERI University offersworld-classresearchfacilitiestostudents with its state-of-the-art infrastructure and well-equipped laboratories. Located at Vasant Kunj in South Delhi, the new TERI University campus has been planned to provide a setting that enhances learning and showcases the concept of modern green buildings. A hostel will also be part of the campus. The Building is designed by Mr.Sanjay Mohe (Architect) and executed by M/S CONFOSS CONSTRUCTIONS, E- 108, Lower Ground Floor, Greater Kailash Enlclave Part – I, New Delhi. Compiled by Mrs Milli Mazumdar & Mrs Priyanka Kochar.
  • 7. The planning and orientation of spaces and building blocks ensures glare-free daylight in all regularly occupied areas. All the liner blocks are oriented in East-West direction with shorter facades facing the sun. The form of the building self shades the glazing such that direct sunlight is blocked at critical times of the day. The exposed facades and walls on the east and west directions have limited glazing. The shading devices are designed such that the windows are completely shaded during the summer, which also contributes to reduction in cooling energy demand of the building. Energyefficiency is furtherenhancedby insulation of the walls and roof; and use of high performance window glazing to minimize thermal gain. Orientation Green features • Insulation of external walls with rock wool. • Insulation on terrace done with vermiculite and puff insulation topped with China mosaic for efficient heat reflection. • Double insulation synergy azur glass is used in external facade with aluminum glazing. • Earth Air Tunnel, Thermal mass and VRV system for cooling the building. • Hunter Douglas louvers and pergolas are used in the building for controlling the intensity of incoming sun rays. • Solar water heating system. • Waste water recycling with STP. Inspired to be GREEN I January - February 2010 I 5
  • 8. The predominant wind direction is taken into account in designing the open space. The hot air from outside moves into the central court where it passes over the water body and fountain. The air thus gets humidified and becomes cooler. This makes the central atrium area always cooler than the surrounding exterior. Use of efficient double glazing window units helps significantly reduce the heat gained through window glazing in the summers and the heat lost in the winters without compromising on the day lighting integration and the levels of visual comfort. The walls that are exposed to the harsh solar rays have a stone cladding which is fixed to the wall by channels. The air gap between the wall and the stone cladding by itself acts as an insulation layer. On the facades rock wool insulation is also provided in the wall. Energy efficiency is further proposed to be enhanced by insulation in the roof slab. Envelope-Design Section through the building To reduce the water demand, buildings in the campus have been provided with low flow fixtures such as dual flush toilets, low flow taps and sensor taps that would result in 25% savings in water use. Further, the wastewater generated from the hostel building equivalent to 8 KL/day will be treated through efficient biological process using a combination of microorganisms and bio-media filter. The treatment system requires low area and energy. The treated water meets the prescribed standards for landscape irrigation. Rainwater run-off from roof and the site would be used for recharge of aquifer. This would enhance the sustainable yield in areas where over-development has depleted the aquifer. Water Management Natural Ventilation
  • 9. Cooling System The campus is equipped with three types of cooling systems, integrated to take advantage of different innovative technologies to achieve energy efficiency. They are discussed briefly as under. • Earth Air Tunnel (EAT) • Variable refrigerant volume systems (VRV) • Thermal storage Earth air tunnel system It is used for free cooling / heating of the building for a major part of the year. This technology uses the heat sink property of earth to maintain comfortable temperatures inside the building. Supplementary systems have been used for extreme conditions (monsoon). In such a system energy savings of nearly 50% compared to conventional system can be achieved. At the campus, this system is used for providing comfort for the rooms in hostel block. The VRV system is a modern air-conditioning system, similar to an efficient version of a split air conditioner. The VRV system is highly efficient under partial load conditions and therefore, has been used in areas with varying occupancies such as the office block, laboratories, administrative block and recreation & dining areas of the hostel block. It features customized control of individual zones. Depending on the cooling demands of the building, variable Thermal mass storage is used in the classrooms. It involves storing energy when available and using it when required. In the proposed arrangement, cooling of the thermal mass is done during night (when ambient temperatures are lower). During daytime when ambient temperature is high, the thermal storage is used as sink for the fresh air requirement. Estimated energy savings of up to 40% can be achieved with this system. refrigerant volumes circulate through the chillers. The VRV system also eliminates the requirement of a plant room; piping & ducting for chilled water; and contributes to 15% energy savings as compared to a conventional air conditioning system. Inspired to be GREEN I January - February 2010 I 7 Variable refrigerant volume systems (VRV) Thermal Mass Storage
  • 10. Artificial Lighting The campus has an efficient artificial lighting system designed for minimizing the energy consumption without compromising the visual comfort in the building. The system takes advantage of day lighting wherever available. Efficient lamps with high lumen output fixed with mirror optics reflectors and bat-wing louvers for glare free uniform illumination have been installed. All fixtures have energy saving electronic ballasts. With efficient designing the lighting loads have been reduced from 2W/m2 to 1 W/m2. In areas where daylight is available, fixtures have been fitted with continuous dimming electronic ballasts. These fixtures are controlled by light sensors, which automatically dim the connected fixtures to achieve uniform illumination required for the task. In areas with non-uniform occupancy, Occupancy sensors that can turn off the lights when the space is unoccupied have been installed. This kind of sophisticated lighting system has a potential of saving 70% lighting energy demand. Day Lighting A View of Admin. Block Teri University Summary In an integrated scenario to achieve efficiency, all the above measures will contribute to 60% energy savings in comparison to a conventionally designed building. The water saving measures will have 25% reduction in the potable water use only by use of efficient fixtures. In addition, reuse of wastewater for irrigation purpose through resource and energy efficient biological process and rainwater harvesting for aquifer recharge would also contribute to efficient water management. Inspired to be GREEN is impressed by the sustainable design of the TERI university and is looking forward to more buildings designed in a very GREEN way.

  • 11. In your Garden • Water the garden early in the morning or late in the evening. This reduces water loss due to evaporation. • Explore water efficient irrigation systems. Sprinkler irrigation and drip irrigation can be adapted to garden situations. • If you have little space in your garden, you could make a compost pit to turn organic waste from the kitchen and garden to soil enriching manure. • While shopping buy fruit and vegetables that are in season to help reduce enormous transport costs resulting from importing produce and, where possible, choose locally produced food. • When buying fish look out for a variety of non- endangered species and buy local fish if possible. At Renovation time • Make the renovations to incorporate green strategies like daylight and ventilation. • Chose low VOC paints and adhesives. • Use local and eco friendly materials & products. • Select water saving fixtures for your toilets and kitchen. • Use BEE rated equipment and appliances. • Recycle the waste generated from construction like scrap & packaging material. • Install CFC free air conditioning equipment with high energy rating. • Improve the building envelope system by installing insulation in roof and walls as well as select a high performance glass window with uPVC frame. At Home • Choose energy-efficient appliances and light bulbs. • Save water: some simple steps can go a long way in saving water like for e.g: you should always turn off the tap when you are brushing your teeth. And try to collect the water used to wash vegetables and salad to water your houseplants. • Let clothes dry naturally. • Keep lids on pans when cooking to prevent your cooker having to work extra hard • Prefer to use gas ovens, Geysers etc in place of the electric ones. • Recycle your paper, glass, plastics and other waste. • Use rechargeable batteries. • Send e-greetings instead of paper cards. At the Office • Use printers that can print on both sides of the paper; try to look into this option when replacing old printers. • Use the back of a draft or unwanted printout instead of notebooks. Even with a double-sided printer there is likely to be plenty of spare paper to use! • Always buy recycled paper - for your business stationery and to use in your printers. • Switch off computer monitors, printers and other equipment at the end of each day. Though in standby mode they're still using power - and that adds to global warming. • Always turn off your office light and computer monitor when you go out for lunch or to a meeting.. Going green is not only about living and working in a Green Building. There are so many ways to go green in your day to day life. If it is simple, fast and gives you the joy of showing your love & respect for our Mother Earth, then why not try these out. Make as many of these tips a part of your life and the environment and your friends will smile back! We need a Green Revolution to save the planet that gives us life.

A meeting of the ways between sophistication and love for the planet. Now every drop counts for two. All of the water that falls into the white ceramic of the washbasin follows an exclusive drainage system. Thanks to a filtering system, the larger waste products are separated out from the water, and only the liquid passes directly into a small treatment tank where it is purified. Each discharge is made directly from this tank, which is connected to the watercloset cistern. In this way, the water supplied is clean and hygienic and is used down to the last drop. Technology in the service of the environment. The exclusive Single Pro faucet series was born out of the same need to find sustainable solutions that respect the environment. For this reason, it saves both space and water. On the one hand, it presents a compact format with smooth, minimalist lines, and on the other, it contains a progressive cartridge which enables water to be saved. In addition, its revolutionary system opens directly in the cold position, avoiding turning on the boiler unnecessarily and so reducing CO2 emissions.

  • 14. GROW YOUR OXYGEN GROW YOUR OXYGEN Oxygen is the very essence of life! However, it is suggested that many of us have low levels of oxygen in our bodies. Over the last several thousand years it is estimated that the amount of oxygen in the air has fallen significantly and now stands at around 21%. However some cities around the world are recording levels of oxygen as low as 12%. At 7% human life can no longer exist. Why has it dropped so much? Simple - man is to blame. We pollute the air with carbon-based fuels and other chemicals and we are destroying our natural oxygen farms, the rain forests. This means more carbon dioxide and less oxygen throughout the world. Many people do not know their bodies are suffering from low oxygen and toxins caused by the effects of pollution and bad diets, but may not recognise the symptoms which include: low energy, interrupted sleeping patterns, frequent colds and infections, poor concentration and general poor health. • Stimulate brain activity • Increase memory capacity • Boost concentration • Develop stronger alertness • Raise energy levels • Improve strength • Build endurance • Detox your blood • Reduce stress • Calm anxiety • Alleviate tension headaches • Remedy irregular sleeping patterns • Help with cardiovascular activity • Prevent lactic acid build up • Strengthen the immune system • Revitalise the skin • Ease hangovers • A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can supply enough oxygen annually to support a family of four! • Over the course its life, a single tree can absorb one ton of carbon dioxide. • Trees help cool down the atmosphere. They can bring down your air conditioning costs by up to 20 percent. What can optimum level of oxygen can do to us?
  • 15. Trees are our breathing partners. We may not live in a forest, but we need trees in order to live. People and animals depend on trees and plants for oxygen. As we breathe in, our body uses oxygen. As we breathe out, it gives off carbon dioxide. Trees do just the opposite. They take in Carbon Dioxide and then release oxygen (which also helps clean the air). Trees also help cool the Earth. Trees give off moisture. More moisture in the air means more rain and all living things need water. Trees cool the air by shading and through water evaporation. They act like huge pumps to cycle water up from the soil back into the air. The 200,000 leaves on a healthy 100 foot tree can take 11,000 gallons of water from the soil and breathe it into the air in a single growing season. Trees are a natural resource that can be renewed - by the planting of trees - replacing the trees that are harvested for use by people. We depend on forest products for things like the wood we burn for heat and the wood we use to make houses and furniture. We use trees for the paper to make books and letters we write. Actually, there are more than 5,000 things made from trees. Trees give us baseball bats, shoe polish, and even tooth paste that comes from tree extracts. Today, the people and companies that manage our nation's forests recognize that trees are a valuable resource and that it is in the best interest of each of us to conserve them. The idea of sustainable forestry means trying to keep things in balance - when trees are cut down to make paper and other products, new trees are planted or regrow naturally. Forests helps wildlife by providing them food and a home. Trees and forests help us by cleaning our air, soil, and water - and provide a place for you to camp and hike! So you can help the world by planting a tree. 1.

  • 16. Why You Need to Live in a Green Home? Introduction "Home is where the heart is and a safe & pleasant place to be. Poor or rich, no children or a dozen children, adults have the control to make any place a good home.” The question that comes to mind, does “safe” only refer to protection from thieves and forces of nature? What about the home being safe for its occupants? Do you actually know the quality of the indoor environment you live in? Does “pleasant” only have to do with the design and interiors? Does it come at the cost of destroying nature and other species on the earth? What kind of world are we leaving for our future generations? Housing in India: It is our responsibility, as residents of India, to look beyond the old paradigm and look at our home, in a broader context and more responsible way. Our homes not only affect our lives, but affect the world around us. A simple step towards a more holistic lifestyle can have compounded effects on our environment. The population of our country has crossed the 1 billion mark and with the energy used by the residential sector is 22% of total energy consumption. A majority of this power comes from coal and oil; both having severe negative impact on the environment. With the economic growth, the housing sector growth has also flourished. The most critical issue is if this growth is sustainable and has a minimum negative impact on the environment. The domestic waste generated in our country which is sent to landfills is also staggering. We all generate waste, but in most countries, a majority of this waste is recycled or reused. Our lifestyle and awareness about the environment is lacking and hence these sustainable practices have not been implemented in majority of homes. We spend more than 85% of our life in an indoor environment and it is not uncommon to live in homes which have inadequate fresh air and ventilation. These are some of the many reasons why all homes to be built, should be designed and built in a sustainable manner. The Home & Its Occupants: Do you have any idea what a major impact the home can have on its occupants? A home can affect our physical as well as mental health. The design of a home can facilitate natural light and ventilation as well as provide a connection to the outdoors. Construction as well as selection of building materials is also critical to ensure no materials are selected, which have toxic effects on the occupant’s health. Countless studies have been done which prove the positive impact of fresh air and daylight can have on individuals. Research shows an improvement of up to 20% in productivity and well being of individuals who work and study in such indoor environment. Children learn better in schools which conform to these standards. Megapolis Pune
  • 17. India has always been Green! Green Buildings and homes is not a new concept, the principles have been successfully done for centuries in the past. Our heritage buildings are great examples of truly sustainable buildings. The Taj Mahal, Red Fort, Hawa Mahal are great examples of buildings which followed these principles to the “T”. The green concepts were also used in residential buildings like the Havelis and courtyard homes. At a time where people did not have air conditioners and artificial lights, the designs had to utilize these free natural resources.Materialswerepredominantlyprocuredlocallyand the waste generated during construction was minimal. And it is such a joy and pleasure, to experience the breathtaking architecture and comfortable indoor environment in any of these buildings. We do not need to reinvent the wheel, we only have to recognize the knowledge and wisdom of our past and incorporate these in today’s context of lifestyle and construction requirements. What is a Green Home? “A green home incorporates smart design, technology, construction and maintenance elements to significantly lessen the negative impact of the home on the environment and improve the health of the people who live inside.” (US Green Building Council) A green home doesn’t cost much more than a regular design but it has a much better market value. Green Homes will approximately cost 3% to 5% more than conventional building constructions. The payback period for the higher investment is around 3 years and will be recovered through the energy & water savings. Benefits of Green Homes • Improved energy efficiency, between 20% to 50% energy savings over conventional homes • Increased water savings, around 30% to 50% • Toxin free materials & natural ventilation for better indoor air quality • Increased use of regional materials & products with recycled content • Promotes use of daylight for better health & productivity • CFC free equipment • Reduces/eliminates negative environmental impact • Improved asset value and marketability Tepeyac Haven Pasco, Washington LEED Gold Certified Taj Mahal Agra Salim Ji Ki Haveli Jaisalmer Hawa Mahal Jaipur Redfort Delhi Margarido House, North California LEED Platinum Certified Inspired to be GREEN I January - February 2010 I 15
  • 18. Designing and building a green home is not a complicated process. The most important factor is the project team’s understanding and commitment to Green. The process of going Green involves the whole project team, i.e. the architect, landscape architect, HVAC, electrical, plumbing engineers, and contractor and for the most benefit, should start at the Conceptual design stage itself. IGBC Green Home Rating System TheIndianGreenBuildingCouncilwithover500committedmembers launched the first rating system for residential buildings in India. IGBC Green Homes is based on the LEED New Construction and LEEDHomesbuthas beenmodifiedtoreflectresidentialarchitecture and construction in India and our culture. National priorities are addressed in Green Homes, water and energy efficiency play a big role next to reduced use of fossil fuels and virgin materials, also handling of household waste and wellbeing of occupants is a criteria for a Green Home. Like in all LEED rating systems certification levels from certified over silver and gold up to platinum are achievable for projects which are reducing the negative environmental impacts. The Rating system consists of six categories and nine prerequisites. Credit Points can be earned under Site Selection and Planning, Water Efficiency, Energy Efficiency, Materials, Indoor Environmental Quality and Innovation & Design Process. The diagram illustrates the importance of each category, and shows that Energy and Water Efficiency together cover more than half of the total 80 Points. The potential of GreenHomesis amazing because75% to 80 % of the real estate demand comes from the residential sector. Developers like Mahindra Life-spaces and Aliens Group took the chance and came up with a completely new definition of residential buildings. These include climate appropriate design, building materials with recycled content, water saving fixtures, VOC free paints, and an energy saving building envelope additional to green areas which help create a healthy environment.

  • 19. 20 Simple Strategies to Go Green: Here are some of the strategies that make a home Green. You do not have to implement all of them but incorporating will make a difference to your operational costs as well as put a smile on Mother Earth’s face: 1. Sustainable Site • Retain at least 25% of the site as vegetated open space • Provide electric charging stations to encourage alternative fuel vehicle • Use a light color (painted or light tiles) to reflect heat away • Chose a site which is close to basic amenities like ATM, shops, schools etc 2. Water Efficiency • Select water conserving fixtures like water closets, faucets and showers • Reduce the amount of turf in the landscape, use native ground covers • Implement a rainwater harvesting plan for all roof run-off water • Install water meters to understand and gauge your consumption 3. Energy Efficiency • Improve building envelope performance by choosing appropriate glass, wall and roof • Install solar hot water heating system • Use efficient lighting technologies and fixtures like CFL’s and LED’s • Use BEE star rated equipment and appliances like air conditioners, refrigerators etc 4. Materials and Resources • Separate waste into recyclables like paper, plastic, metal and glass at source • Specify materials with high recycled content like AAC blocks, glass and steel • Procure materials locally (within 500 kilometres) • Reuse salvaged and refurbished materials / products when possible 5. Indoor Environmental Quality • Architectural design to provide adequate daylight and views for all spaces • Use LOW VOC (volatile organic compounds) paints, adhesives, sealants and carpets • Utilize natural ventilation when possible and design to accommodate cross ventilation • Perform building “flush out” before occupancy, to remove construction contaminants. The process of going Green is of course, much simpler and easy to implement in a new construction than in an existing home. From the above checklist, existing homes can implement these during renovation. Conclusion: Green homes are, simply put, better homes. Homes built to these standards are energy & water saving, provide its occupants with an indoor environment which positively affect their health, reduce the impact on the nature and most importantly show our commitment and concern for our future generations.

  • 20. Designing Homes with Adequate Natural Ventilation & Daylight Designing Homes with Adequate Natural Ventilation & Daylight We all know that a good home should provide an indoor environment for occupants with adequate natural ventilation and daylight. “More easily said than done” is a statement that holds true when you have analyzed some of the homes in our cities and realize that and these basic requirements have not been satisfied in all cases. Have you ever noticed the abundance of fresh air and daylight in any historic building or home? These were spaces which did not have air conditioning or artificial lights, and hence attention was paid to utilizing free natural resources. These buildings combined the use of materials, innovative technologies and understanding comfort related issues in buildings. The fact that these buildings are still functioning and pleasing to the eye is testament to the greatness of our heritage and wisdom. Designers today, tend to overlook this challenge, only to hide the deficiencies in the built environment through artificial means. The role of an architect, is far greater than the designer of an aesthetically pleasing elevation and functional plan, and also includes understanding the comfort of occupants. Natural ventilation and daylight have been proven through countless studies to improve health, productivity and overall well-being of the occupants. So does your home meet these minimum standards or do you need to rethink the environment you spend a majority of your life! Windows: Daylight vs. Heat Gain Daylight (which we have abundance of in India) needs to be carefully managed and dealt with in the design of buildings. While the light from the sun is critically important, the heat needs to be controlled. How often have we seen glass box buildings, which have more glare than light, resulting in curtains and blinds being closed and artificial lights burning through the day. The windows are responsible for bringing in light and heat and hence the design should address both issues. The R value (resistance to heat transfer) of a window (high performance) is about 1/4th of a opaque wall, hence the placement, performance, size and shading are critical. • North or South orientations preferred • Appropriate shading for all windows • Specifications of VLT (visible light transmittance), Solar Factor / SHGC and U value • Windows between 2’6-7’6” contribute to views, above 7’6” are for daylight only • Frame – uPVC are most energy efficient • Light shelves for spaces of larger depths Glazing Factor = WindowArea [SF] Floor Area [SF] x ( VLT x Constant) Constant Values: Windows on wall : 0.2 Skylight : 1.0 Another rule of thumb is that light will penetrate 1.5 times the height of the window and hence for larger floor plates, courtyards can be introduced based on this calculation. A simple rule of thumb to achieve daylight is to achieve 2% with formula below:
  • 21. Natural Ventilation: The movement of air from the outside and through a space is termed as ventilation. Ventilation is critical to replenish the oxygen and remove contaminants in a space. A common issue known as “Sick Building Syndrome” is observed in building with inadequate fresh air being supplied and the spread of germs and a general uncomfortable feeling is experienced by the occupants. Many designs claim ventilation by providing a window per space. This is incorrect, as for air to flow, there needs to be an inlet & outlet for air and some type of convective or pressure system. This is evident in any traditional home design incorporating courtyards. The courtyard is a store for cool air and windows open into the court. Equally important are the high level ventilators on the opposite side of the room, which when vented, create a negative pressure in the space, whereby drawing in the cool air from the courtyard. While designing homes, a simple rule of thumb for fenestration to achieve adequate natural ventilation is as follows: Please note that this refers to “openable area” and hence the type of window is critical – sliders allow only 50% operable and should be calculated. Space Type Openable areas as a percentage of total carpet area Living Spaces 13% Kitchens 10.5% Bathrooms 5% Conclusion: A healthy and productive indoor environment is the result of careful and intelligent design. A design incorporating natural daylight and natural ventilation would certainly not cost anything more and the benefits are both monetary and intangible. Buildings are made to keep us safe, happy and healthy. It’s up to us to demand this from our architects, MEP, building material & product manufacturers and the design & construction industry.

  • 22. Author: Mr. Abhay Desai Director Marketing South Asia. HEALTHY HIGH PERFORMANCE CLEANING A pathway to Sustainable Cleaning Clean is just the beginning Just imagine where we would be today without the means to remove harmful and unwanted contaminants from our buildings. Contaminants like bacteria, viruses, molds and fungi can adversely affect human health. Common dirt dust and soils can be contaminated with pesticides and other chemicals. Poor indoor quality is often associated with improper cleaning products and procedures. Aside from the obvious impact on health issues (respiratory illnesses, allergies, headaches etc) the cleaning products and procedures can also impact an organization financial bottom line. Without a doubt cleaning is important to protect our health as well as the buildings in which we live and work. Also Users of cleaning products are increasingly aware of the need to conduct cleaning operations in a way that is ‘environmentally friendly’. But this doesn’t just mean using chemicals that are safe for the environment, it means minimizing all the many other environmental impacts that arise in making and using cleaning products, such as energy consumption and waste disposal. The term ‘improving sustainability’ is used to refer to making an improvement in the overall impact of cleaning. There are three key steps, which are required to optimize sustainability: • Choose products that are designed for sustainability as well as safety. • Work with suppliers so that they responsibly manage their manufacturing impacts. • Minimise the environmental impacts that arise during your cleaning operations. Step 1: Choose products that are designed for sustainability as well as safety. a) Require your vendor to declare the list of banned ingredients. b) Ensure that the manufacturer produces enough evidence of the fact that the ingredients are selected not just for safety but optimize sustainability of the finished product when used diligently. Step 2 Work with vendors so that they responsibly manage their manufacturing impacts. a) Ask your vendor for evidence that they have effective control of impacts during the manufacturing phase. Key areas include: • Minimising raw material and finished product wastage during manufacture. • Minimising consumption of energy and water. • Minimising emissions to sewer and atmosphere and, in particular, controlling emissions of hazardous substances to avoid risk to people or the environment. • Minimising packaging waste and recycling used packaging. • Operating an Environmental Management System. • Operating procedures to prevent accidental emissions. • Operating Occupational Health & Safety systems to protect staff. Step 3 Minimise the environmental impacts that arise during your cleaning operations. How? • Define what task the cleaning products will be used for and buy products which deliver the required performance. • Analyse and reduce rework rates. First time cleaning is essential to minimise waste, particularly in energy intensive operations such as machine dishwashing. • Favour more concentrated products, where applicable. • Dilute and use products according to the manufacturer’s instructions using accurate dosing systems where appropriate. • Service cleaning equipment regularly, particularly critical items such as dosing pumps for automated machines. • Train staff, for example using BICSc courses which detail out the way we handle cleaning chemicals. Smart building owners and managers in organizations from across all sectors and industries are taking actions to reduce the negative impact of s of their facilities. Healthy High Performance Cleaning programs are designed to improve a buildings environmental quality and sustainability with a cost neutral or cost reduction impact on operations. It is a unique, all inclusive approach to cleaning that helps ensure a clean and safe work environment, increase employee productivity and satisfaction and enhance the value and integrity of buildings while reflecting organizational mission and values. The HHPC program starts with environmentally preferable chemicals then offers proven cleaning strategies, procedures and purchasing guidelines for consumables, tools and cleaning Equipment. With a HHPC program you get: 1. A clear perspective on the need for green cleaning and green cleaning concepts. 2. Cleaning strategies procedures and guidelines backed by the most up to date training support tools. 3. Environmentally preferable janitorial guidelines for chemicals, paper tools and cleaning equipment. 4. A pathway to earn credits towards certification under the LEED for existing buildings Green building Rating system The Healthy High Performance Cleaning takes traditional cleaning beyond appearances with procedures designed to make your building the safest, healthiest, and the cleanest it has ever been. The most important step is to understand that cleaning plays a huge role in the health of the buildings occupants. Cleaning also directly affects the asset value of the building. The end goal of the HHPC program is to simplify the lives of customers by providing more than environmentally preferable cleaning products and helping them achieve safe, healthy, high productivity facilities.

Ground Source heat pumps In contrast, the Geo-Thermal Heat Pump uses the same type of compressorized refrigeration system to remove heat from the building, but it transfers the heat into the temperate earth and not into hot air. Because it is easier to move heat to the cooler earth than into the sweltering summer air, Geo-Thermal Heat Pumps do not have to work as hard to cool your home. This efficiency has a bottom line - substantial savings reflected in your monthly utility bill. When heating, the compressor system of the Geo-Thermal Heat Pump uses the heat energy stored in the earth to efficiently heat your home while other heat pump systems are laboring to gather heat from the frigid outdoor air, or are even freezing up. Because Geo-Thermal Heat Pumps utilize such a large amount of the earth’s stored energy, they are typically more efficient than even heaters which burn environmentally damaging fossil fuels. Geo-Thermal wonder works by taking advantage of the near constant temperature of the earth which exists only a few feet below the surface. For example, when cooling, air- to-air heat pumps and other air conditioning units found in most homes actually remove heat from the air in the building through their compressorized refrigeration mechanisms and move the heat to the outdoors where they attempt to expel it into the air. As summer progresses and the average daytime temperatures raise, these other units find it more difficult to expel this heat into hot air- the system actually loses efficiency and labors to keep up with cooling demands.

Can you tell us about your background and what made you give up the practice of law to be a green consultant? Well, because of my background, I like to think that I bring a unique skill set to the eco-consultant facilitation marketplace. I’m also amazed how the blessings of life have worked out so poetically in my case. When I was in college and law school I was extremely active in the budding green movement. Then I graduated and-like many of my lawyer peers- you chase the position that offers the best benefits. Unfortunately, commercial insurance litigation firms won over green-advocacy. (Laugh) However, it couldn’t be more perfect because for fifteen years I assembled all the skill sets necessary to become an ‘all round’ consultant and facilitator. As a litigation attorney, your stock and trade is your ability to deeply and fully find and analyse every factor that can influence a case one way or the other. You also have to get inside your opponent’s head and you have to know every detail of your client’s business. Many of my peers would interview clients in their air conditioned offices and soft leather chairs...not me. I came from a business background...my great- grandfatherstarted a hardware store that still operates today. For me, there’s nothing like understanding someone’s operations by studying it -first-hand- in the field. So, I’d frequently be found wearing a hardhat on construction-sites, spending long nights with Madras IIT techs doing copywrite forensics for Mumbai-based BPO platforms, or wearing hip waders for a due diligence for commercial fishing vessel. The advantage it gave me when it came time to stand-and- deliver in front of a judge or jury was immense. So when I achieved the freedom to choose my career path, I let my heart lead and brain follow. I harmonized my international legal, business and economic background with my passion for the green movement. I also utilized my deep network of experts in India and U.S. to build my consultant ‘dream team.’ The benefit of my experience is that I know how big and small businesses think. Plus we’ve finally arrived in an age where ‘going-green’ makes business sense beyond CSR (corporate sustainability and responsibility). It’s unfortunate that we need to think that way, but the reality is that businesses (by and large) only start thinking CSR when their bottom lines are fat or if they have an image they need to protect. So now we in the green industry have the distinct advantage of offering solutions that allow businesses to fatten their bottom lines regardless of their dedication to sustainability. I guess that’s another advantage of being a former lawyer with a business background- you become very practical and economic minded in your approach.
  • 31. Tell me about your consultation company Peerless Green Initiatives? What is PGI? The PGI mission ethos is two-fold in that it consults and is an advisory; and it is also a network portal that creates and facilitates project and business plans to fruition. PGI also is adept at creating and securing strategic relationships -tie ups- domestically and internationally, between privates, NGO’s and public- private partnerships. At PGI, we’re skilled at vertical integration of process and can offer end-to-end solutions that can really impact the research, development or supply of new green technology, materials and processes. We’re all pleased with the economic ties that our respective countries are establishing. It’s very encouraging for the green industry as well as combating global warming, which obviously knows no political borders. When a group from Madras IT won the New York ‘Next Big Idea’ award, that made us at PGI very excited and inspired to continue pushing the envelope of green business development. What is the scope of PGI’s range of services? We focus on four areas: energy, sustainable building, responsible agricultural practices, and ‘green’ certifications (LEED, WFTO, FLO, Organic to name a few.) Then we have two sub-sectors: support of rural primary education and environmental crisis management. We couple that with creating and negotiating domestic and cross-border U.S.-India strategic alliances for the best development and use of the state-of –the-art; funding core missions through public private partnerships and NGO’s and so on. What I can say philosophically, regarding PGI’s ethos, is that we use our wide reach network to be a force multiplier for clients. To use the sourcing vernacular... our core group has extensive vertical penetration along a wide horizontal spectrum. Translation please? Ha...yes,ok. Wellwehaveasourcoresomeofthefinest in the industry in areas including LEED architecture/ engineering/construction, energy R&D techs, organic horticulturists, conservationists and IT engineers. Our sciences-set is what makes us ‘peerless.’ We overlay that with top-shelf professionals in business, vertical integration, supply-lining, trade practices, law, economics, licensure, government relations/ lobbying and media. That set is what makes us able to facilitate tie-ups and projects. That’s the ‘initiative’ aspect of what we do. So you live and work in India? Yes, and I love it. Before starting Peerless Green Initiatives (PGI) I was general counsel to many U.S. companies with interests in India and I was enamoured with the development of India as an up- and-coming economic power. Also some of my closet colleagues were Indians and NRI’s and I really cliqued with their balanced business mindset. The best thing about getting into the green movement in India is that it doesn’t come with a lot of the other baggage that exists in certain sectors. Media and politics worry about border threats, business sector worry about outcompeting China...but the green-set flies above all that, and with the growing amount of Government incentives and great institutions like the India Green Building Counsel, we’re witnessing a period of innovation that makes every other Indian sector envious. (Laughing) It true...I mean, in the U.S. the government has been providing massive incentives for promotion and innovative of green business models, and I’m pleased to see the Indian Government, particularly in Tamil Nadu, has joined in introducing strong incentives for the development of green non-grid-dependent solutions for the burgeoning energy building and agricultural demands. Economic scientists like Steven Levitt and Stephen Dubner have shown that people respond strongly to strong incentives. Those incentives, for example LEED, World Fair Trade and Fair Trade Labelling fuel the engine of green innovative development. Inspired to be GREEN I January - February 2010 I 29
  • 32. I could fill a volume with all the India economic forecast data in my head. But it suffices to say ‘going green’ is not a luxury- its mandatory if India is to continue its current trajectory. It’s a well quoted fact that 6% of India’s grid potential comes from wind energy, but only 1.5% is being utilized...reason being that all the incentives were put into facilitating erection of turbines but not for their on-going operation. That’s where PGI focuses. Building relationships, alliances and using its lobby arm to balance the benefits. We’re very holistic in our project approach and it pays dividends for our clients and the industry as a whole. What do you see as the industry’s; your company’s greatest challenge? I think we’re facing the same challenge as the rest of the industry....how to distribute the concept of using eco-sustainable alternatives in sectors accustom to conventional ways and means... sectors that are often addicted to non-renewables, fossil-fuel and grid dependency. It disturbs me to see these massive 1000+ unit development plans for North Chennai with no CSR plan in mind. We have to enlighten that sector that incorporating LEED principles at the planning stage is vital to the region’s survival...literally. They should put as much analysis in sustainable building factors as they do determining whether the building foundation is on solid footing. What advice would you give to green business owners and start-ups? Those starting ventures or growing existing ventures need to have a solid business-plan but when the calculations lead to questions of risk, the unavoidable fact is that is the cost of being a pioneer... of being entrepreneurial. I gave a lecture at Kodai International School and I used the example of Henry Ford (who by the way planned his model T to run on corn alcohol) who failed three times before starting his successful brand. The students were shocked and we had a lively discussion regarding the value of failure. Being unafraid of failure, and seeing failure as an opportunity for future modification and success, changes one’s risk tolerance and their perceptions about risk. I know I’m sounding like I’m a mix of Donald Trump and J. Krishnamurti, but you know, I read Krishnamurti’s compendium ‘On Fear’ probably ten times through my life and you find that it applies so easily to business that I credit much of PGI’s meteoric success to his vision. My personal value-added to consulting venture start- ups is that I’ve represented 1000’s of businesses as a lawyer and you end up ‘living’ their successes as well as learning what mistakes they’ve made. I have immense first-hand knowledge regarding suitable strategies and where the snares may lie. So to those business owners I say that these are exciting times we are living. Never in the history of Man have the stakes been so high, and never has mankind had to change its habits and infra-structure more dramatically. If you’re not willing to be part of it, you’re in trouble, because the ‘risk analysis’ of not being part of it is fatal. Literally. I think I have a right to comment because I’m an American who loves living in American and I decided that I could make the difference I want by being maverick and having my boots-on-the-ground here in India. And I love the experience of consulting here. I’m pleased to say that I’ve had more than a few hesitant clients –in India and US- who I’ve helped ‘see the light’ and exercise their spirit of entrepreneurialism effectively, and now they enjoy life at the helm of healthy companies or tied in fruitful US-India relationships. Let me finish this interview by thanking Inspired to be Green for this opportunity and it providing the industry with such a quality and timely periodical. It’s a great source of information, insight and a terrific forum. Mr.Frank Costanzo PEERLESS GREEN INITIATIVES www.peerlessgreen.net frank@peerlessgreen.net

  • 34. GREEN BUILDING CONSULTANCY by Mr.Rumi Engineer, DGM, Godrej & Boyce. Growth is necessary for development of individual and nation as a whole. India’s growth rate is pegged at modest 8% . Construction Industry has significant contribution in India’s GDP. There are modern day evils associated with developmental measures adapted today. Development should adapt sustainable measures and Focus on Environmental benign impacts. Hence whenever one thinks of constructing/ renovating a building… Think green. Why Green …. Green is an iconic word for sustainability. sustainability encompasses features like site , water, energy, materials and indoor environmental quality IGBC has been spearheading the movement since past couple of years. Myth #1 : Green Buildings are costly..? Incremental cost solely depends on project’s baseline cost. Now a days in competitive environment the baseline has improved considerably with respect to the past hence incremental cost is marginal. Green building is not a Cost but an Investment which pays back in form of rich dividends to all the stake holders year on year. Myth #2 : Green Buildings result in time overruns..? Normally a construction project of 10 Lac sq.ft built up area, takes 2 years minimum or more to complete. There is no activity in the green building certification which will span more than the project completion time lines. All the activity runs parallel to the project activities. There is absolutely no chance of project time lines getting impacted. Myth #3 : Green Buildings … lots of documentation..? Documentation by way of drawings, calculations and technical submittals is anyway done for all the projects. Same documentation is compiled and collated in a structured manner which benefits the project’s design team and facility staff who operates the building. Benefits of going in for a Green Building • Win-Win situation for all the stake holders. • Energy & water savings features considered and built in right from the design. • Measurement and verification of the energy & water consumption in the building. • Measurement & verification will bring in the accountability and help in optimization of resource use and result in cost control. • Goodambience(internal&external)fortheoccupier. • Waste management & recycling of materials helps reduction in pollution and burden on landfill.
  • 35. Godrej Green Building Consultancy renders services in three different areas. 1. Facilitation. 2. Energy & Lighting simulation. 3. Fundamental and enhanced commissioning. Facilitation : Facilitator is an anchor to the project team guiding them through entire journey of certification process. • Conduct training for the team members to understand the gamut of documentation. • Review the status of documentation. • Sharing wealth of information for sourcing of vendors, materials. • Evaluation & promotion of new technologies. • Review the documentation prior to submission. • Interpret the review by the assessor and explain to project team. Energy & Lighting Simulation : Prior to freezing up of designs, materials and equipment specs, simulating the building design on the software goes a long way in helping the designer to make judicious decision. Similar exercise can be taken up for lighting design. Day light consideration with glare control is very important aspect in the lighting design. Simulation facilitates the designers by displaying virtual images of the interiors to gauge the situation which will be prevalent after construction. For commercial green buildings it is mandatory to meet the ASHRAE 90.1.2007. In Cores & Shell project it is mandatory to demonstrate 14% saving over and above the ASHRAE 90.1.2007 benchmark. Chunk of Investment in a building is attributed to 1. Glazing : High performance double glazed unit assembly 2. Roof Insulation : Overdeck roof insulation 3. HVAC : High efficiency chillers, pumps, motors, drives, heat recovery wheels 4. Indoor air quality : CO2 Sensors, demand control ventilation To optimize on the CAPEX one needs to have best mix & match of the above measures mentioned above. In absence of energy & lighting simulation exercise, it is virtually not possible to arrive at best efficiency measure suitable for the project. Inspired to be GREEN I January - February 2010 I 33
  • 36. Fundamental & Enhanced Commissioning Building design has world class architectural features, robust and versatile HVAC design, selection of Hi-Eff. equipments etc. Will the building systems operate as intended and results in the savings..? The answer is emphatic NO ! In any building be it green or non-green the systems in the building have sub-systems which are interactive with each other. This complicates the matter hence one requires to test and integrate the systems. Fundamental commissioning commences right from the design stage, continues through the construction stage and ends with the project completion. Design stage is very critical to understand the projects requirement and also work jointly with the MEP consultants to optimize the Capex. Even operation and maintenance cost has to be given due consideration during design stage itself. Verifying of system performance at site and co-relating with the design is known as Testing and Commissioning (T & C) of systems. There are different type of T & C performed, some may be sampling and other could be 100% comprehensive. Preparation of system manual and training to facility staff is one of the important feature of fundamental commissioning. Enhanced Commissioning : After completion of project, post occupancy this period is very critical in any project. The project team hands over the systems to facility staff, smooth transition is what one looks for. Commissioning agent facilitates the process and carries on with the review of the operations of the system and also help resolve the pending issues in the project. Measurement & Verification Proof of the pudding is in eating! One cannot improve till one measures one’s performance, keeping in mind this adage, measurement and verification is like having display panel in the car. Imagine driving a car without the display panel. No indication of how much fuel is left, what is the oil level, engine temperature and what speed are we driving etc. With all the herculean efforts put in through out the journey at end if one does not have robust monitoring system in place how can one gauge the benefit derived from all the initiatives taken up for energy and water optimization. Commissioning, measurement & verification is very critical to all the building be it green or conventional. Energy simulation, commissioning, measurement & verification are a must for all the buildings to realize the potential of energy and water saving. In a building Operational and Maintenance (O & M) cost outweigh the capital investment. The analogy is of iceberg. Cap (30%) of iceberg is the CAPEX and the base, which one cannot fathom underneath (70%) is the operations and maintenance cost. A modest Target of 10% Saving in Operation & Maintenance Costs will outweigh the 20% saving in the Capex.
  • 37. VisitattheConstro2009 A really green home at the showground All visitors could see how simple green principles are implemented. Compressed paper boards were used for the ceiling, Bamboo was prominently used as furniture and green walls formed an attractive indoor space. The exhibitors showcased their products and could feature their systems better than at a “conventional” exhibition. The ‘Eco-Friendly Model Home’ is a compilation and assembly of various ‘green materials’ like recycled plywood, energy savings paints, UPVC windows, to name a few. Around and outside the Model Home, there was a display of numerous materials. A film on application of eco-friendly materials and methods was run at intervals inside the model home. Usually professionals are aware of the need to use green; however, the actual system of using it, right from identification and sourcing the material to the execution and inter-linkage of the technologies is a matter of detailing which is non –standard. This essentially means that there is a gap between the awareness of the principles and the need, to the actual usage of the materials and technology at professional level. In addition, there is a need to educate the common man, the client, the customer, the buyer and the end-user. Many a times, this role of an educator falls upon the designer, the architect or builder. While the desire to be and design green is present, one is usually unable to translate into reality due to incomplete knowledge. It was expected that the Eco-friendly Model Home present in Constro along with the stalls for the materials and technology providers was covering required aspects completely. While the actual house demonstrated the usage, the looks, the inter-linkage etc, the details as regards pricing, availability and other administrative aspects were available in the stalls. One could obtain end-to-end information for actual design and execution of the ‘Eco-friendly Model Home’.

  • 38. As bamboo is a very “green”, rapidly renewable and versatile building material – the Contro in Pune showcased also a “Bamboo-House”. TheBamboohousewasclearinganymisconceptions about bamboo and perceived limited usages! In fact, it should inspire many a visitor to actually use bamboo in their projects. Since ‘seeing is believing’, this attempt to create a structure in bamboo got sceptics to rethink! Additional information and guidance about bamboo was available from the personnelatthestallfor‘NationalBambooMission’ thus, one obtained end-to-end information for actual execution of bamboo usage. How Green is Bamboo? • Bamboo is not a tree – it’s a grass, and it grows like one, many species of bamboo can grow two feet or more a day. • When it’s harvested, it need not be replanted, because it will grow a new shoot from its extensive roots system. • Bamboo renews itself readily, unlike hardwood trees, which once cut, are gone forever. • Bamboo is an endlessly renewable resource. • Bamboo is a viable replacement for wood. It is one of the strongest building materials, with a tensile that rivals steel and weight-to-strength ratio surpassing that of graphite. • Bamboo is a critical element in the balance of oxygen and carbon dioxide in the atmosphere. • It helps reduce the carbon dioxide gases blamed for global warming. • Somebambooevensequestersupto12tonsofcarbon dioxide from the air per hectare, which makes it an extremely efficient replenisher of fresh air. • Bamboo plays an important role in construction industrybecauseofitsversatilityandappropriateness for affordable housing in India. • Potential of Bamboo as construction material has been already explored, experimented and implemented by designers, engineers, and institutions like KONBAC, National Bamboo Mission and INBAR to name a few.

  • 39. With COFFOR stay-in-place formwork technology, eco- friendly construction is possible without compromising on TIME, QUALITY and COST of construction. Its an eco-friendly company, making "green" products. Their product is "eco-friendly" because it allows the use of various "green" filler materials, i.e. laterite, clay, ash, which reduces the use of concrete for GF and GF +1 structure. Depletion of natural resources is reduced, as less wood is used compared to conventional structures and also much less water compared to brick masonry. Use of brick is decreased/eliminated, reducing the amount of natural resources and energy used to make them. The use of oils to clean metal sheeting is eliminated. Transportation is reduced (saving Gasoline) as COFFOR panel can be folded flat for shipment. This uses far less space than brick trucks. For example, 1 house can be constructed in 1 container of COFFOR panel, as opposed to almost 5 trucks of brick. The company manufactures locally, eliminating need for international shipments. Coffor's operating practices are also eco-friendly, for example, 1 tree was planted for every 1000sq.ft. of developed landscape area for their latest project.

The LFA campaign is an initiative of Soma Waste Management, Auroville, in collaboration with Eco Service and many volunteers from Auroville - to be more precise: over 1800 people participated in the days activities, significantly higher than the organizer expected! LFA wants to make all of us aware of our waste-generating behaviour and of the need to upscale waste management in Auroville. Its an extraordinary event which took place in Auroville, the town project aiming at human unity as envisioned by Sri Aurobindo and The Mother. 25 teams of children from twelve schools, of employers and employees, and of residents and guests were single-mindedly involved in a sweeping clean-up action, clearing roads and roadsides of carelessly discarded litter throughout the city and its immediate environment. “That’s not all”, says Ribhu, one of the young coordinators of LFA, the “Litter-free Auroville” campaign. “We heaped up the collected garbage and demonstrate its segregation and sorting, to ensure that most of it can later be recycled. We had an interactive exhibition with games, puppet shows, quizzes, pledges, and lots of information on global and local pollution and on composting and recycling.” The Litter Free Auroville Concept
  • 43. The Strategy behind Litter Free Auroville: Goals 1. Waste avoidance and reduction. 2. Pollution free environment. These are high aspirations and long term goals, but we felt that all initiatives should be steps forward towards achieving these goals. Objectives • Awareness: To promote and create awareness on positive waste disposal practices and the impacts of waste on the environment (air, water, soil). • Actual waste clean-up: To have the highest community participation in AV to date in collecting litter in half a day in AV. Create aplatform for change:To createan interactiveplatform for the exchange and dissemination of ideas and advocacy of best practices. Develop ideas and translate them into action which would be a step towards reaching our goals. • It is very much an objective of this campaign so I strongly felt it should be included with the other two.
