In-fill development, that increases density, is inherently better than building on undeveloped (Greenfield) sites. Materials are assessed at their life cycle analysis (LCA) in terms of their embedded energy, durability, recycled contents, minimum wastes and their ability to be recycled. It can be obtained locally to reduce the embedded energy cost of transportation or salvaged from reclaimed materials at nearby sites. Materials for construction should be obtained from natural, renewal sources managed in a sustainable manner. Prithvi (Bhumi, earth)- Sustainable sites & materials, Apas (Jal, water)- Water efficiency, Agni (Fire)- Energy efficiency, Aakash (Space)- Daylight & atmosphere, and Vayu (Air)- Indoor environmental quality & pollution measures. In Indian context, a Green Building construction contains, as its components, all Panch-bhootas (5 manifestations of nature), i.e. A World Wildlife Fund (WWF) survey report reveals that, 100 cities, including 30 in India, may face acute water shortage by 2050. There has been an increase in nearly 700% commercial energy consumption in the last four decades and there is water shortage of nearly 225 million liter per day (mld) in major Indian cities. The government had informed the Lok Sabha that by 2050, nearly 60% of the population will live in cities as India’s rate of urbanization is dramatic. In India, as per census 2011, nearly 31.16 % population are living in urban areas. ![]() ![]() The concept is also termed as 3P approach – People, Planet and Profits. It is based on “Triple Bottom Line (TBL)” benefits, which accounts for social and environmental performances in addition to financial performance. A green building in its design & construction minimizes negative impacts. To tackle this source of global warming, “Green Building” concept has evolved.Ī Green Building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less wastes & pollutions and provides healthier space for its occupants as compared to a conventional building. Depleting natural resources, rapid industrialization and urbanization have led a negative impact on the environment and life-cycle. According to UNEP, these buildings are a major source of carbon emissions (nearly 39%) causing global warning. The time varies from 60 to 90 percent depending upon the nature of jobs and livings. inside the buildings, which may be their homes, offices, hospitals, shops, factories, educational and other places. People spend major part of their life time indoor i.e. Nature's call for 'Green Building' revolution
