Heat Island Effect: Roof |
| Intent |
Reduce heat islands (thermal gradient differences between developed and undeveloped areas) to minimize impact on microclimate and human and wildlife habitat |
 |
| Requirement |
OPTION 1: Use roofing materials having a Solar Reflectance Index (SRI)3 equal to or greater than the values in the table below for a minimum of 75% of the roof surface. OR OPTION 2: Install a vegetated roof for at least 50% of the roof area. OR OPTION 3: Install high albedo and vegetated roof surfaces that, in combination, meet the following criteria: (Area of SRI Roof / 0.75) + (Area of vegetated roof / 0.5) >= Total Roof Area Roof Type Slope SRI Low-Sloped Roof = 2:12 78 Steep-Sloped Roof > 2:12 29 |
