Listed below are links to sites that will provide you with more information about cool roofs.
The Cool Roof Rating Council (CRRC) is an independent, non-profit organization that develops radiative energy performance rating systems for roofing products.
The non-profit organization was launched in 2010 to accelerate a world-wide transition to cooler, healthier cities. Its mission is to advance urban heat island mitigation policies and programs to promote more efficient and comfortable buildings, healthier and more resilient cities, and to cancel some of the warming effects of climate change through global cooling. Its Toolkit includes a primer and implementation guide for cool roofs and cool pavements as well as a knowledge base of various other resources.
Energy Star is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy specifying energy efficiency criteria for cool roofs and other products.
On this site find you will find information about the Building Technologies Program envelope materials research and development projects on cool roofs.
This links provides publications, webinars, and resources about the heat island effect.
This site provides an interactive map of the U.S. providing state energy code adoption information for residential and commercial codes.
The CoolCalifornia.org cool roof content was developed by the Heat Island Group at Lawrence Berkeley National Laboratory under contract to the California Energy Commission and the California Air Resources Board.
