Facade Material Identification for Optimizing Building Energy Consumption Across Various WWRs for ECBC(Code) Compliant Buildings in Warm-Humid Climate, India

Increase in population has led to increase in built up environment around the world. The demand for a better lifestyle has developed a high pressure on the Energy Sector to keep up with the day-to-day needs. Increased demand in jobs have caused an increase in the commercial buildings in India. Even today India depends highly on non-renewable sources of energy to meet the energy demands. To regulate the demand and supply chain, India has various energy policies, some mandatory and some a voluntary schemes. Energy Conservation Building Code 2017 is one such policy which is mandatory in only very few states in the country. The study in this paper demonstrates how the use of this energy policy on the building envelope along with Window-To-Wall Ratios help in reducing building’s Energy Performance Index and helps conservation of energy consumption in the long run. The existing building envelope taken from the case example is documented on-site and recorded. The case example considered in this study is situated in the Warm and Humid Climate zone of India. The application of ECBC 2017 and further Design Alternatives to the building envelope, observes a reduction of 32% when compared to the contemporary.
