The CRRC is a U.S.-based 501(c)(3) nonprofit organization established in 1998 that develops fair, accurate, and credible methods for evaluating and labeling the radiative properties of roofing and exterior wall products. The mission of the Cool Roof Rating Council (CRRC) is to bring objective, scientific information related to cool surfaces to critical discussions and informed decisions about the impacts of heat islands, extreme heat, and energy use in the built environment. The CRRC Rated Products Directories list the surface radiative property ratings for thousands of roofing and exterior wall materials.
