Cool roof policy

April 5, 2023

India’s first cool roof policy was recently announced by Telangana government to reduce the impact of heat on building.
Cool roof policy is mandatory for all government and non- residential commercial buildings.
It aims to make buildings thermally resilient and reduce their energy consumption.
Occupancy certificate would only be given after compliance.
A cool roof is mandatory for residential buildings that have a plot area of 600 sq yards or more. For those with a plot area of 600 sq yards or less, it is optional.
It enumerates three different materials to insulate the roof
- Paints or liquids with high reflectivity (lime wash or white plastic coating),
- Prefabricated material like poly-vinyl chloride (PVC) membranes or bitumen-based sheeting,
- High albedo, ceramic mosaic tiles or shingles.
