• BEC outlines sustainable building design interventions that cut down energy required to provide cooling and heating.
Key Highlights of the report:
• Global energy demand and carbon emissions from the building sector have been on the rise.
• Building and construction sector account for more than a third of global energy use. This could go up to 50% by 2060 without concerted action to increase energy efficiency of buildings.
• Space cooling was the major contributor to the increasing energy demand and grew by 33% between 2010 and 2018.
• It suggests BEC as an efficient regulatory tool to decarbonise the building sector. However, as of 2019, less than 75 countries had or were developing a mandatory or voluntary building energy code.
• In India, Energy Conservation Building Code (for commercial buildings) was launched in 2007 by Bureau of Energy Efficiency (BEE). Its main objective is to establish minimum requirements for energy efficient design and construction of buildings.
• In 2018, a separate energy code for residential buildings, Eco-Niwas Samhita, was launched.
