A building should create delight when you enter, serenity & health when occupied and regret when departed. A Green Building is a major attempt in this direction! Indian Green Building Council GREEN BUILDINGS – SOME KEY FACTS

U.S.G.B.C. UNITED STATES GREEN BUILDING COUNCIL I.G.B.C. INDIAN GREEN BUILDING COUNCIL L.E.E.D. LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN

U.S.G.B.C L.E.E.D. Non-profit organization committed to expanding sustainable building practices. working to advance structures that are environmentally responsible, profitable, and healthy places to live and work. Members includes building owners and end-users, real estate developers, facility managers, architects, designers, engineers, general contractors, subcontractors, product and building system manufacturers, government agencies, and nonprofits. LEED is the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED gives building owners and operators the assessment tools to measure their buildings’ performance. Architects, real estate professionals, facility managers, engineers, interior designers, landscape architects, construction managers, lenders and government officials all use LEED.

How are credit points awarded under LEED-INDIA?
Credits are awarded based on five categories of performance:
1. Sustainable Sites
2. Energy and Atmosphere
3.Water Efficiency
4.Indoor Environmental Quality
5.Materials and Resources
Projects can earn additional points
Innovation in Design category,
demonstrating exceptional performance above LEED-INDIA requirements.

1. Sustainable sites
Start by selecting a site that is well suited to taking advantage of mass transit.
Protect and retain existing landscaping and natural features . Select plants that have low water and pesticide needs, and generate minimum plant trimmings. Use compost and mulches. This will save water and time.
Recycled-content paving materials, furnishings, and mulches help close the recycling loop.
BACK

2. Energy and Atmosphere
Building shape and orientation , passive solar design, and the use of natural lighting.
Develop strategies to provide natural lighting .
Install high-efficiency lighting systems with advanced lighting controls. Include motion sensors tied to dimmable lighting controls. Task lighting reduces general overhead light levels.
Use a properly sized and energy-efficient heating/cooling system in conjunction with a thermally efficient building shell. Maximize light colors for roofing and wall finish materials, install high R-value wall and ceiling insulation, and use minimal glass on east and west exposures.
Minimize the electric loads from lighting, equipment, and appliances.
Consider alternative energy sources, such as photovoltaics and fuel cells, that are now available in new products and applications. Renewable energy sources provide a great symbol of emerging technologies for the future.
Computer modeling is an extremely useful tool in optimizing design of electrical and mechanical systems and the building shell.

3. Water Efficiency
Design for dual plumbing to use recycled water for toilet flushing or a gray water system that recovers rainwater
Minimize wastewater by using ultra low-flush toilets, low-flow shower heads, and other water-conserving fixtures.
Use re-circulating systems for centralized hot water distribution .
Install point-of-use water heating systems for more distant locations
BACK

4. Indoor Environmental Quality
Eliminate poisons and toxic off gases
Use more of natural light
Less noise by using sound absorption materials and methods
Views to the outside
Air quality and thermal comfort
The quality of these who work in green buildings are more productive and take fewer sick days
Sick Building Syndrome has been attributed to poor air quality caused by air-tight construction and the off-gassing of volatile organic compounds (VOCs) from such things as finishes, adhesives, furniture systems, wall coverings, office machinery, and in some instances, molds.
The release of harmful VOCs (such as carcinogenic urea formaldehyde) is one of the biggest concerns when choosing products and materials for interior spaces . As such, indoor air quality (IAQ) is on most radar screens these days, and anyone specifying green products for certification or just seeking to create a healthy interior space will find myriad resources.
BACK

5. Materials and Resources
Select sustainable construction materials and products by evaluating several characteristics such as reused and recycled content, zero or low off-gassing of harmful air emissions, zero or low toxicity , high recyclability , durability, longevity, and local production. Such products promote resource conservation and efficiency. For example, GREENGUARD is an independent, non-profit organization that certifies interior products and finishes.
Use dimensional planning and other material efficiency strategies. These strategies reduce the amount of building materials needed and cut construction costs. For example, design rooms on 4-foot multiples to conform to standard-sized wallboard and plywood sheets.
Reuse and recycle construction and demolition materials . For example, using inert demolition materials as a base course for a parking lot keeps materials out of landfills and costs less.
Incorporate a solid waste management program that prevents waste generation.

What are the benefits of LEED-INDIA certification?

LEED-INDIA certification is third-party validation of a building's performance.
LEED-INDIA certified projects blend environmental, economic and occupant - oriented performance.
They cost less to operate and maintain, are energy- and water-efficient ,
Have higher lease-up rates than conventional buildings in their markets
Physical demonstration of the values of the organizations that own and occupy them

BENEFITS OF GREEN BUILDINGS
Environmental benefits :
Reduces impacts of natural resources and consumption
Economic benefits :
Reduces operating costs, is cost effective in the long run
Health and safety benefits
Enhances occupant comfort and health
Community benefits
Minimizes strain on local infrastructures and improves quality of life

GROWTH OF GREEN BUILDINGS IN INDIA

GREEN BUILDINGS IN INDIA

CII-Godrej GBC - Platinum rating and first green building in India
Daylight used to light substantial area of the office. Microcontrollers are used to monitor the brightness and augment this light with artificial lighting where necessary, thus saving electricity without compromising on the quality of the work environment
Fresh air to the AHUs is precooled in the two wind towers that sit on either side of the building. Precooling reduces the load on the air conditioning system. Saves 60% of cooling energy requirement compared to buildings of similar size.
Green Roof : Lawn trays, made out of recycled plastic protects against heat ingress through the roof while providing a green and pleasing surrounding
North facing skylight allows the use of daylighting for the entire space. This is achieved by using high performance double glazed glass which helps the building lay lesser stress on both its artificial lighting and cooling systems
The building is special also because its construction combined ancient practices with modern architecture , reaffirming the applicability of traditional architectural knowledge to today's notions of sustainability .

ITC Green Centre, Gurgaon - Platinum rated building
Zero water discharge
53 per cent energy savings over a conventional building
40 per cent reduction in potable water use
Use of treated grey water for flushing and landscaping
Use of fly-ash in bricks & concrete,
High efficiency equipment
Eco-friendly housekeeping practices
Well designated green education programme.

Wipro Technologies, Gurgaon - Platinum rated building
Traditional inward looking haveli plan that performs varied functions -- designed to form a light well, it acts as a micro-climate generator , thus reducing energy consumption; mutual shading of the courtyard walls keeps them cooler than outside walls; a big water-body and vegetation in the middle of the courtyard reduces its temperature by evaporative cooling.
Channeling the direction of sunlight and wind , insulating walls, or having the right kind of windows
Insulated rooftops and terrace gardens that again reduce the solar gain of the building.
Grass concrete pavers on the outside surface of the building area reduce storm water run-off and decrease the heat-island effect caused by asphalt pavers
3R concept: reduce, reuse and recycle :more than 10% of the bldg materials are salvaged from an old bldg, recycled: 10% fly ash based AAC blocks, acoustic cladding, glass, ceramic tiles, MDF board ,95% of materials got locally from around 500 miles all around, rapidly renewable materials like interior partitions made from MDF board made from bagasse and agricultural waste
Certified wood ; more than 75% of the virgin wood NIS certified by Forest Stewardship Council

Grundfos Pumps, Chennai - Gold rated building and first green building in Chennai
95 per cent of office lighting is natural
100 per cent of the sewage recycled
No trees cut during construction
Building caters for the needs of the physically challenged
Co2 sensors to monitor indoor air quality
Use of low VOC carpets, paints, adhesives, sealants
VFD’s for fans and pumps (based on the fluctuation in the air-conditioning demand from the end user, VFD changes the frequency and hence the rpm of the motor thereby saves energy)
Air cooled high efficiency chillers with a COP of 2.7

NEG Micon, Chennai – Gold rated building
The building uses vermi-composting to treat canteen wastes, the compost is used on the premises.
Installed wind turbines of 950 KW offsite to cater to 100% of energy req. entered into agreement with the state to wheel the power generated into the bldg.
The building envelop consists of a double layered cavity wall to prevent heat penetration
Eco friendly housekeeping materials help keep the Indoor Environment Quality healthy.
The indoor air quality is enhanced by continuous purging of fresh air into the building.
Low flush water closets, sensor based urinals, low flush faucets in the toilets to reduce water consumption
The grey water is treated and used for irrigation instead of being released into the municipal drainage
Uses low mercury content bulbs which cause less environmental pollution when discarded,
95% of waste recycled

From 2 to 4 to 40, green buildings are springing up all around us… Who knows you or I may be afflicted by the Sick Building Syndrome…. Who knows tomorrow Spiderman may refuse to clamber onto non green buildings.. So let us begin to decrease environmental degradation by………………. Thank you!
