Pradhan Mantri Awas Yojana (PMAY), Government of India’s flagship program aims to provide affordable housing to urban and rural poor. Launched in 2015, the PMAY – U (urban) is targeting to build approximately 12 million dwelling units by 2022. Each dwelling unit is around 30 – 60 sq m in area (depending on the category such as economically weaker section (EWS) or low income group housing (LIG)). As a result, the expected addition to the building footprint by 2022 will be at least 360 million sq m. This is equivalent to 25% of the existing commercial building footprint (AEEE, 2017).
The focus of the Mission is to build fast and deliver units at an affordable price within the specified period. Housing that is built as part of PMAY will last 40-60 years and decisions taken today will have an impact on the level of comfort that these dwellings provide to its occupants and the energy use, costs and associated carbon emissions over the lifetime of the building. Building design, materials and construction all have an impact on how much additional (operational) energy is needed to reach comfort levels in the buildings. Additionally, a large amount of energy is embedded in the extraction, manufacture/ processing of building materials and the construction process itself, which adds to the overall energy required to build and operate these dwellings.
With support from Shakti Sustainable Energy Foundation (SSEF), AEEE has carried out this scoping study to identify potential opportunities as well as research and data gaps, for mainstreaming thermal comfort and energy optimization in affordable housing. The study’s objective is to assess the mission targets (building stock analysis) to understand the type of housing being built and highlight the energy impact (embodied and operational) of building design and construction within affordable housing segment. This is a first step towards understanding the energy impacts and pathway consequences of affordable housing construction under the PMAY-Urban mission.
