Site Sustainability - Heat Island Mitigation with Cool Walls Pilot Credit

Leadership in Energy and Environmental Design (LEED) is the U.S. Green Building Council's (USGBC) voluntary green building certification system. The USGBC published a LEED v4.1 Heat Island Mitigation pilot credit for solar reflective walls 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.

The credit is worth one possible point under the Heat Island Reduction Sustainable Sites Credit for the Building Design and Construction (BD+C) rating system. 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
