ABSTRACT

The growing demand for energy in the building sector drives the need for change from fossil fuels to environment-friendly power sources which can also mitigate the effect of global warming and climate change. One of the initiatives to knock down the peak load and energy demand in buildings is stepping toward energy-efficient buildings for a sustainable future. This paper aims to review the fundamental aspects for approaching net zero energy consumption buildings (nZECB) keeping into consideration the effect of building physics and challenges faced in the pathway and its feasibility. Also, it addresses various policies and plans that can dramatically change the future of developing nations like India toward a zero-emissions energy system. Considering all the facts, this study suggests inflating our focus beyond direct energy use and opt for hybridized clean energy sources and enhance the constructional parameters for a better, greener, and cleaner future.
