Leadership in Energy and Environmental Design (LEED) is the U.S. Green Building Council's (USGBC) voluntary green building certification system. Under LEED Version 4.1, one point will be awarded for the installation of a solar-reflective wall product under the Heat Island Reduction Sustainable Sites Credit for the Building Design and Construction (BD+C) rating system. When a solar-reflective wall product is used for the heat island reduction credit, the CRRC Wall Rated Products Directory (available in 2022) can be used to find products that meet the requirements. 

The USGBC published the “Heat Island Mitigation with Cool Walls” pilot credit on April 9, 2021. The intent of the credit is to reduce the Urban Heat Island (UHI) effect through the use of solar-reflective exterior wall products.

To achieve the credit, at least 75% of the building’s gross exterior wall area (including vertical fenestration) must be surfaced with a wall material that has a solar reflectance of at least 0.60 and thermal emittance of at least 0.75. 

Please Note: The CRRC has summarized the pilot credit for the convenience of CRRC users. The CRRC does not intend to interpret the credit requirements.
