Tamil Nadu launched India’s first State-level Standard Operating Procedure (SOP) for Cool Roof Coating Application on 5 June 2026, marking World Environment Day.
The SOP provides a 12-stage standard framework for applying cool roof coatings in homes, schools, and public buildings.
It aims to reduce urban heat, lower rooftop heat absorption, and improve indoor thermal comfort.
The SOP was developed by the Tamil Nadu Green Climate Company (TNGCC) and the Tamil Nadu Climate Change Mission (TNCCM).
It was prepared in collaboration with the United Nations Environment Programme (UNEP) and SEEDS Technical Services.
Cool roof coatings are reflective materials applied on rooftops to reduce building temperatures and energy consumption.
