The existing residential building stock accounts for a substantial portion of worldwide energy consumption and greenhouse emissions. Improvements to the thermal performance of existing buildings is a vital activity to mitigate climate change, and often has additional benefits in the form of improved comfort, health and well-being for occupants. Despite the extensive body of literature in this area, it remains a difficult task to assess the performance of retrofit packages in occupied residential buildings.

Residential energy efficiency interventions are complex social and construction programmes that may benefit health, yet the interactions between the material improvements, health and health-related outcomes, and householder responses are not well understood. While indoor winter warmth and householder satisfaction have been identified as the key mediators for physiological, mental and social health outcomes, this paper explores how programme contexts may have influenced the outcomes. This review revealed that common target populations were low income households, children and the elderly.

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.
