Many recent major studies, including the IPCC’s Fourth Assessment Report, have attested that energy efficiency is humanity’s prime option to combat climate change in the short- to mid-term. The potential to avoid CO2 emissions cost-effectively has been reported to be significant through efficiency policies. However, the review of global research findings on the quantification of cost-effectiveness of opportunities through improved efficiency has highlighted that there is a major shortcoming in the vast majority of such calculations.

The building sector is considered as the biggest single contributor to world energy consumption and greenhouse gas emissions. Therefore, a good understanding of the nature and structure of energy use in buildings is crucial for establishing the adequate future energy and climate change policies. Availability of the updated data is becoming increasingly important in order to allow a rigorous analysis. In this paper, recent data on the world energy consumption in both residential and commercial buildings are reported.

The white paper puts forward recommendations for the coordinated enhancement of policies, codes, and regulations. It lay out a framework for guidance for the Ministry of Housing and Urban Affairs (MoHUA), the Ministry of Health and Family Welfare (MoHFW), and the Review Committees of the Bureau of Indian Standards (BIS) for the National Building Code (NBC), to harmonise their actions for healthy affordable housing in urban areas.
