The Cool Roof Rating Council (CRRC) is a 501(c)(3) nonprofit organization that develops accurate and credible methods for evaluating and labeling the surface radiative properties (solar reflectance and thermal emittance) of roofing and exterior wall products. The CRRC also provides education to the public on how solar-reflective roofs and walls can help improve building energy efficiency, increase occupant comfort, mitigate the Urban Heat Island effect, and reduce greenhouse gas emissions. 

History OF CRRC

The CRRC was established in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance of roofing products and to disseminate the information to all interested parties through the CRRC Rated Products Directory. In 2018, the CRRC membership approved an expansion of the organization’s scope and mission to include the rating of exterior wall products.


  • To implement and communicate fair, accurate, and credible radiative energy performance rating systems for roof or wall surfaces
  • To support research into energy related radiative properties of roof or wall surfaces, including durability of those properties
  • To provide education and objective support to parties interested in understanding and comparing various product options

By pursuing this mission, the CRRC will become the recognized informational resource for reducing the Urban Heat Island effect, increasing building energy efficiency, improving occupant comfort, and mitigating the global climate effects of greenhouse gas emissions.

Product Rating Program

At the core of the CRRC is the Roof Product Rating Program, a fee-for-service program that provides financial support for CRRC operations. The program enables roofing manufacturers to have roofing products tested and labeled with radiative property information through a strict program administered by the CRRC. Code bodies, architects, building owners and specifiers rely on the rating information provided in the CRRC Rated Products Directory. For further information, please see the Product Rating Program page.

The CRRC is working in collaboration with stakeholders on the development of a rating program for exterior wall products. The CRRC Wall Rating Program will be similar to the CRRC’s Roof Product Rating Program, with product ratings based on the surface radiative properties of exterior wall products. A Rated Products Directory and CRRC Product Label will be created for wall products to help end users identify rated products and their radiative property values. The new program is anticipated to be launched in early 2022.


The CRRC's diverse membership includes anyone who is interested in rating roof or wall surface radiative properties and in the energy efficiency of roofs or exterior walls. Our members include manufacturers, suppliers, and distributors, as well as contractors, consultants, environmental advocacy groups, government agencies, educational institutions, code bodies, energy service companies, and other interested individuals. For more information on how to become a member, please visit our Join the CRRC page.

Membership is distinct from the Product Rating Program. Membership is optional and not required for the rating of products, nor is membership automatic if products are rated by the CRRC.
