ABOUT THE WALL PRODUCT RATING PROGRAM
Last Updated May 13, 2020
The CRRC is currently exploring the development of a Wall Product Rating Program in collaboration with industry. The proposed 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. Recent research by LBNL found that solar reflective walls can save as much energy as a cool roof.
In 2019, the CRRC membership amended the organization’s bylaws to permit the rating of exterior wall products. A steering committee comprised of 21 members representing manufacturers, government, utilities, building enclosure experts, and other interested parties are currently working on the program design and a funding model, which will be described in a proposal to the CRRC Board of Directors (Board). The Board will consider approval of the proposed program in mid-2020. If approved, the launch of the Wall Rating Program is anticipated for spring 2022.
Let us know if your organization is interested in participating in the Wall Rating Program. Industry participation primarily means having wall product(s) rated by the CRRC. Other opportunities for participation include:
- Becoming a CRRC member,
- Serving on a Wall Rating Program Committee, and/or
- Utilizing wall product ratings to identify, require or promote solar reflective walls through policy or voluntary program.
