The GCCA Cool Roofs and Pavements Toolkit is a hub of information on urban heat islands and mitigation technologies. The toolkit includes a searchable knowledge base of more than 500 studies, pictures, videos, presentations, and programmatic documents. You can also check out the Forum to ask questions, find answers, and interact with others.
For basic background, the toolkit also has downloadable primers that explain the science of cool, reflective surfaces and highlights how cities implement policies to reduce excess urban heat.
The Toolkit is updated on a regular basis, so check back often to find the latest cool news and science.
