Welcome to the Cool Surfaces Toolkit

Explore scientifically supported resources about solar-reflective “cool” surfaces and how they play a role in energy efficiency and affordability; mitigation of the urban heat island effect; and climate resilience.

Visit the Cool Reflections Blog for news and fresh perspectives; download the Cool Roofs and Cool Pavements Primer for detailed information and guidance; and use the Knowledge Base to browse over 600 peer-reviewed articles, case studies, and other publications on cool roofs, walls, and pavements.
