Green Building

Green buildings aim to reduce environmental impact throughout a building's lifecycle. They use less energy, water, and materials and create less waste than conventional buildings. The key aspects of green building design are sustainable site planning, water and energy efficiency, indoor environmental quality, and material selection. India could significantly reduce its energy usage and greenhouse gas emissions by adopting green building practices more widely. Various rating systems have been developed in India to evaluate how well buildings implement green features.

WHAT IS GREEN BUILDING????
WHAT IS GREEN BUILDING?  Green building refers to both a structure and the using of processes that are environmentally responsible and resource- efficient throughout building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition.  Green building design involves finding the balance between homebuilding and the sustainable environment.
WHY GREEN BUILDING?  World wide , building sector and it’s related activities consumes:  40% of energy  25% of woods  15% of water  40% of raw material  39% of CO2 emission (in USA)  It also contribute to 40% of the waste send to landfill
WHY GREEN BUILDING?  A green building uses less energy, water and other natural resources creates less waste and green house gases and is healthy for people living or working inside as compared to a regular structure  .According to TERI estimates, if all buildings in Indian urban areas were made to adopt green building concepts, India could save more than 8,400 megawatts of power, which is enough to light 550,000 homes a year.
MAIN POINTS IN GREEN CONCEPT  Sustainable site design  Water quality and conservation  Energy efficiency  Indoor environmental quality  Material and resources
SUSTAINABLE SITE DESIGN “A site plan that has the least environmental impact while still meeting the clients project goals.” Important points includes:  Site layout  Impervious surfaces  Sustainable landscape design
Site layout:  Energy saving of 20%+  Elongate on East/West axis  Maximise North & South exposure for day lighting  Minimize East & West facing windows
 Building Orientation Source: www.nachi.org/building-orientatio
Impervious surfaces:  Limit ground water recharge  Increases pollutant load  Create heat island effect
Source: http://www.mdcoastalbays.org
Reduce impervious surfaces by :  Pervious pavement  Planting in and around parking area  Green roof Source: https://en.wikipedia.org/wiki/Green_roof
Sustainable landscape design by:  Preserve existing plants  Landscape irrigation using water from showers and sinks  Soil management techniques, including composting kitchen and yard wastes, to maintain and enhance healthy soil that supports a diversity of soil life
WATER QUALITY AND CONSERVATION  It can be carried out by:  Rain water harvesting  Reuse and recycling of water  Use of modern water fixtures
Rain water harvesting:  Direct use  Indirect use Source: http://www.renewableenergyworld.com
Reuse and Recycle of water:  Grey water: The relative clean waste water from baths , sinks , washing machine and other kitchen appliances.  These grey water , after proper treatment can be reused for toilet flushing and irrigation of plants

 Use of modern water fixtures reduce wastage of water to a great extend
ENERGY EFFICIENCY  The most important element of green building is energy efficiency. Higher energy efficiency reduce carbon emission.  It can be achieved by following ways:
 Maximize the use of renewable energy like solar energy , wind energy, geothermal energy etc Source: http://www.renewableenergyworld.com
 Roof top or pole mounted wind turbine:  Cuts electricity bill  Performance depends on type of turbine and location Source: https://www.sustainable.com.au
 Using all energy efficient appliances  Use daylighting  Using smart lighting  Use led lightings Source: www.pinterest.com/daylighting
INDOOR ENIRONMENTAL QUALITY  Indoor Environmental Quality (IEQ) encompasses the conditions inside a building—air quality, lighting, thermal conditions and their effects on occupants or residents.
Air quality:  Low Volatile Organic Compound (VOC) paints  Moisture resistant building material  Materials and system that require only simple, non toxic or low VOC methods of cleaning should be used
Lighting:  Daylighting: It uses natural daylight as a substitute for electrical lighting.  An effective daylighting strategy appropriately illuminates the building space without subjecting occupants to glare or major variations in light levels, which can impact comfort and productivity.  Use tinted glass and doubly glazed glass can beused

Stack ventilation: The stack effect describes the passive movement of air through a building resulting from differences in vertical pressure developed by thermal buoyancy. When air inside a building is warmer than the outside air, the warmer, the less dense air will rise. Stack ventilation takes advantage of this effect by constructing openings in the building envelope high at a substantial height, allowing the warm air to escapeSource: https://en.wikipedia.org/w

MATERIAL AND RESOURCE EFFICIENCY The points to be noted under this includes:  Low energy and durable materials  Low site impact- no destruction of trees, retained site vegetation  Use of flyash concrete  Use of locally available materials
Eco cement:  Eco-Cement is a brand name for a type of cement which incorporates reactive magnesia or magnesium oxide, another hydraulic cement such as Portland cement, and optionally pozzolans and industrial by-products.  Ordinary Portland cement requires a kiln temperature of around 1450 °C. The reactive magnesia in Eco-Cement requires a lower kiln temperature of 750 °C, which lowers the energy requirements, and hence the use of fossil fuels an emission of carbon dioxide (CO2).
RATING SYSTEM IN INDIA Whether Green buildings are really green is to be decided against the predefined rating systems. There are three primary Rating systems in India.
RATING SYSTEM IN INDIA Whether Green buildings are really green is to be decided against the predefined rating systems. There are three primary Rating systems in India:  Green Rating for Integrated Habitat Assessment (GRIHA)  Indian Green Building Council (IGBC)  Bureau of Energy Efficiency (BEE)
GRIHA  GRIHA is India’s own rating system jointly developed by TERI and the Ministry of New and Renewable Energy, Government of India.  The process initiates with the online submission of documents as per the prescribed criteria followed by on site visit and evaluation of the building by a team of professionals and experts from GRIHA Secretariat.  GRIHA rating system consists of 34 criteria categorized in four different sections. ( 1) Site selection and site planning, (2) Conservation and efficient utilization of

Indian Green Building Council (IGBC)  The Leadership in Energy & Environmental Design (LEED) is the rating system developed for certifying Green Buildings  LEED is a framework for assessing building performance against set criteria and standard point of references.  Confederation of Indian Industry (CII) formed the Indian Green Building Council (IGBC) in year 2001  Indian Green Building Council (IGBC) has licensed the LEED Green Building Standard from the USGBC. IGBC facilitates Indian green structures to become one of the green

Bureau of Energy Efficiency (BEE)  BEE developed its own rating system for the buildings based on a 1 to 5 star scale. More stars mean more energy efficiency.  The unit of Kilo watt hours per square meter per year is considered for rating the building and especially targets air conditioned and non-air conditioned office buildings.  The Reserve Bank of India’s buildings in Delhi and Bhubaneswar and many other buildings have received BEE 5 star ratings.

CONCLUSION  Indians were aware of Green Building concepts from the beginning. Conventional homes with baked red colour roof tiles and clay made walls is a really good example of energy efficient structures that are used to keep cool during summers and warm during the winters. Most of rural India is still attached to this building technology with naturally available materials like clay, wood, jute ropes, etc. 
CONCLUSION  In this rapidly changing world, we should adopt the technology that helps us to save precious natural resources. This would lead us to true sustainable development. Source: http://www.thegreenmarketoracle.co
