The crrc does not set a minimum definition for cool.
Roof temperatures crrc.
The energy commission recognizes the cool roof rating council crrc for rating the solar reflectance and thermal emittance values of roofing products.
The cool roof rating council was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance radiative properties of roofing products and to disseminate the information to all interested parties.

Decra s line of cool roof colors are certified by the cool roof rating council crrc to have high solar reflectance and thermal emittance properties that reduce energy costs by lowering roof temperatures.

The crrc publishes the measured solar reflectance and thermal emittance values in their online rated products directory and on crrc product labels for use by roof specifiers codes officials architects contractors engineers and building owners.
Reduce energy costs with a cool roof.
Both properties are measured from 0 to 1.
These properties help lower roof and attic temperatures on hot sunny days to reduce the need for air conditioning.
The crrc administers a product rating program in which companies can label roof surface products with radiative property values.
