Indo-Swiss Programme on Building Energy Efficiency (BEEP) Globally buildings account for 35% of energy use and about 20% of GHG emissions. In India, buildings even consume 40% of all energy and cause 40% of CO2 emissions. Phase 2 of BEEP has shown that 30-45% of energy savings are possible in India with marginal additional costs compared to the current way of constructing. Based on the achievements of the previous phase, Phase 3 will focus on mainstreaming and scaling-up energy efficient and thermally comfortable building design and on promoting the on-site use of renewable energy sources.
