Tamil Nadu issues SOP for cool roof as pilot projects record drop in indoor temperatures
The Tamil Nadu government has released a standard operating procedure to scale up the use of cool roof coatings in public and private buildings. This initiative follows successful pilot projects that demonstrated a significant reduction in indoor temperatures during summer months.
Why it matters
This policy provides a scalable, low-cost passive cooling solution to mitigate the health and energy impacts of rising urban heat.
After pilot projects in a city government school and a Perumbakkam housing complex showed that cool roof coatings could lower indoor temperatures by up to 5°C during peak summer, the Tamil Nadu government on Thursday released a State-level standard operating procedure (SOP) to scale up the intervention across homes, schools and public buildings. Launched on June 5, marking World Environment Day, the SOP is intended to standardise the implementation of cool roof coatings, which is a passive cooling measure that reflects solar radiation and reduces heat absorption by building surfaces. The document was released by Environment and Climate Change Minister V.K. Rajeev and Forests Minister R.V. Ranjithkumar.
