ANNOUNCEMENTS
India is aiming to become a 5 trillion-dollar economy by 2025. With economic growth, the demand for energy will also increase and so does the associated emissions. The Indian building sector is the second most energy-exhaustive sector expending one-third of the total final energy demand is about to witness the fastest growth among all regions of the world through 2040, driven by rapid economic progress, increasing per capita income, budding population and growth in urban areas. It is expected that, India will augment 40 billion m2 of new buildings by 2050. Improving building energy efficiency is of vital importance for curbing the ever-growing building energy demand. Using LEAP and eQUEST v3.65, this study will measure the growth of the building sector and effects of mitigation policies and the associations between the energy drivers and the future building energy demand through a technologically detailed service-based building energy model. The result of the study reveals that the residential and commercial building energy demand is expected to reach 7.89 EJ and 8.18 EJ, respectively. With the penetration of efficient appliances and fuel change from traditional biomass to contemporary clean energies, 23-38% of residential energy can be saved in 2100 as compared to business as usual scenario. ECBC upgrades energy efficiency in commercial buildings and possibly will reduce commercial office building energy demand by 55-75% in 2100 business as usual scenario.
