United Nations Environment Programme (UNEP) has stated that “No Other Sector has such a High Potential for Drastic Emission Reductions then the Building Sector”. India can be a Major Contributor to it if its Green Building Revolution picks up but for that, Government Policy and Private Sector must work in sync.
The oldest existing and still followed definition of a green building is that given by the Office of the Federal Environmental Executive in US as “the practice of 1) increasing the efficiency with which buildings and their sites use energy, water, and materials, and 2) reducing building impacts of human health and the environment, through better siting, design, construction, operation, maintenance, and removal throughout the complete life cycle.” The genesis of the green building concept might appear to be a consequence of the evolution of the 1990s global warming paradigm, green buildings existed much earlier. London’s Crystal Palace and Milan’s Galleria Vittorio Emanuele II, both built in the nineteenth used roof ventilators and underground aircooling chambers to regulate indoor air temperature. However, it was the OPEC oil embargo in 1973 that proved to be the first catalyst. With gas lines stretching for blocks, few American experts started to question the complete reliance on fossil fuels and thus began serious level researches into energy efficient buildings. Today, with climate change and energy security at the forefront of global negotiations, developing countries like India are fast hopping onto the bandwagon. But, a lot needs to be achieved by government to unleash the potential of the sector and make a huge impact in securing India's energy future.
Currently, buildings globally use 32 per cent of the world's resources in construction. They are responsible for around 40 per cent of global energy use and generate up to 30 per cent of global Green House Gas (GHG) emissions. The United Nations Environment Programme (UNEP) has stated that “no other sector has such a high potential for drastic emission reductions” than the building sector, and the Intergovernmental Panel on Climate Change (IPCC) has identified that buildings offer some of the most cost effective and expedient ways to reduce GHG emissions. Recognizing that energy use and air pollution are intertwined with India's sustainable development, the NDA government enacted the Energy Conservation Act, 2001 (ECA 2001) which promotes energy efficiency and conservation domestically. The Act mandated the creation of the Bureau of Energy Efficiency (BEE), imparting it the authority to establish an Energy Conservation Building Code (ECBC). BEE issued the first ever National Building Code of India (NBC) in 2005, but the issues of energy efficiency were marginally addressed in it. However, in 2007, the Ministry of Power together with BEE issued ECBC —the first stand alone national building energy code in India. Though it currently stands as voluntary, ECBC establishes comprehensive minimum energy efficiency requirements for building envelope, lighting, HVAC and electrical system installed in buildings.
