Cool Roof Rating Council (CRRC)

The CRRC is a 501(c)(3) non-profit organization formed in 1998 to develop accurate and credible methods for evaluating and labeling the radiative properties of roofing products and to disseminate the information to all interested parties. In 2019, the CRRC expanded to include the rating of exterior wall products.

Visit our website. 

Mission and Vision 

The CRRC’s Mission 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’s Vision is that CRRC data and resources on the impacts of cool surfaces enhance individual and community resilience to extreme heat.

Validation Testing Program Overview Webinar

When: April 17, 2024, 10:00am - 11:30am PT
Where: Online webinar
Cost: Free

CRRC staff are excited to share upcoming changes to the Random Testing program. Random Testing is the CRRC’s quality assurance mechanism which verifies product ratings to maintain the credibility of the Rated Roof Products Directory.

Random Testing is being replaced with a new quality assurance program, Validation Testing, which will have a completely different set of requirements and procedures. CRRC Licensees are encouraged to attend this webinar to learn about the program, as all Licensees will need to comply with program requirements to maintain their CRRC product ratings.

The webinar will include Q&A and a recording of it will be made available for those who cannot attend.

Rated Roof Products Directory 

The CRRC Rated Roof Products Directory is a free, online database that can be used to identify roofing products that comply with various building codes, financial incentives, and voluntary green building programs (e.g., LEED, Green Globes). 

Each of the products on the CRRC Directory has a CRRC product rating that indicates the radiative performance (solar reflectance, thermal emittance, and Solar Reflectance Index (SRI)) of the roofing product. 

Knowing the radiative performance of roofing products is important for understanding the roof’s impact on building energy use, occupant comfort and the surrounding environment. 

The CRRC Directory currently lists over 3,000 roofing products and is the only database of its kind in the U.S. since the sunset of the US EPA ENERGY STAR program for roofing products in June 2022.

What is a Cool Roof?

A cool roof is one that strongly reflects sunlight (solar energy) and also cools itself by efficiently emitting any heat that was absorbed. The roof literally stays cooler and reduces the amount of heat conducted into the building below. If a building does not have air conditioning, this keeps the building cooler and a more constant temperature. 

If a building has air conditioning, the equipment does not have to work as hard. Imagine wearing a white or a black T-shirt on a hot day. By wearing the white T-shirt you will remain cooler than if you wore a black T-shirt because it reflects more sunlight and absorbs less heat. Cool roofs, like a white T-shirt, keep the internal temperature of the building lower. 

However, a cool roof does not need to be white. There are many "cool color" products which use darker-colored pigments that are highly reflective in the near infrared (non-visible) portion of the solar spectrum.

Become a Member!

CRRC membership is open to any individual or organization with an interest in the building envelope, energy efficiency, urban cooling, and/or the testing and rating of solar-reflective building surfaces. CRRC membership is divided into two classes.

Why Join?

  • To have a voice in the direction of the CRRC
  • To demonstrate your organization's leadership in the market
  • To vote on critical issues
  • To interface with other industry leaders and actors interested in the building envelope, energy efficiency, urban cooling, and surface reflectivity
  • To elect Board members
  • To serve on the CRRC Board of Directors
  • To serve on a CRRC committees

CRRC Annual Meeting 

The Annual meeting is a yearly tradition where CRRC members and other stakeholders come together to hear about the latest industry research and CRRC activities; provide input on direction and cast votes for the Board of Directors; and socialize with fellow members and staff. The meeting is open to both members and non-members. 

The Annual Meeting also consists of a series of guest speaker presentations. The purpose of guest speaker presentations is to provide CRRC members and non-members with timely, accurate, and valuable information relevant to reflective building materials, with all viewpoints on cool roofs and cool exterior walls accepted. Technical information is supported by scientifically rigorous studies and presentations do not serve as a platform for advertising or promoting certain products or services. 

The next CRRC Annual Meeting will be held on Wednesday, June 5, 2024. Stay tuned for details on the meeting location, sponsorship opportunities, and guest speakers!
