Buildings account for ~30% of electricity used in India. An estimated 1.3 billion square meters of new commercial floor space will be added in India over the next 20 years -- approximately twice of what
exists currently. Commercial sector electricity consumption has been growing at 12-14% per annum on average over the last few years. The demand-supply gap in electricity and peak power availability continues to widen, while over 40% of Indiaâ€™s population does not have access to electricity. Even with access to electricity, on-site power generation using diesel generators and gas generators are the norm in India, and these account for ~10-20% of the total electricity consumed.
Therefore, a Net Zero Energy Building (NZEB) initiative for all new buildings in India is imperative, so that on-site renewable energy generation becomes integral to bridging the national energy demand-supply gap. This initiative also ties in well with the National Solar Mission, which targets an addition of 22 GW of solar power by 2022, of which 2 GW will be set aside for off-grid installations. Coupled with the accompanying policy support (incentives and subsidies), progressive policies will, over time, make NZEBs economically viable. This is particularly relevant at the scale of net zero energy communities. An appropriate approach to bring a step-change in reducing energy consumption in the building sector will entail developing the right policies as well as the scientific, technical and research capabilities. In this context, the establishment of an academic-industry-government consortium (an enhancement of the Public-Private Partnership model) can enable technology and knowledge transfer to make NZEB for all new buildings a reality in India.
USAID ECO-III Project has started a joint Net Zero Energy Building (NZEB) initiative with the objective to develop commercially competitive NZEBs along with promotion of off the shelf, cost-effective technologies that facilitate NZEBs by 2020 in India.
