Cooling homes, improving lives
REFLECT is a global research programme testing how cool roofs perform in real-world conditions.


By reflecting sunlight and lowering indoor temperatures, cool roofs offer a practical way to reduce heat, improve health, and enhance everyday comfort—particularly in communities most affected by extreme heat.
