Tamil Nadu Releases SOP for Cool Roof Coating to Reduce Urban Heat
On World Environment Day, Tamil Nadu launched India's first state-level Standard Operating Procedure (SOP) for cool roof coating to address urban heat. Developed by state agencies with UNEP and Seeds Technical Services, the SOP standardizes a 12-stage process for applying solar-reflective coatings on homes, schools, and public buildings. Pilot projects showed roof surface temperatures dropped by 6-8°C and indoor temperatures by 4-5°C, potentially reducing cooling energy demand by up to 20%. The initiative aims to expand passive cooling measures statewide.
