Reduce heat islands (thermal gradient differences between developed and undeveloped areas) to minimize impact on microclimate and human and wildlife habitat.
Provide any combination of the following strategies for 25% of the site hardscape (including roads, sidewalks, courtyards and parking lots):
- Shade (within 5 years of occupancy)
- Paving materials with a Solar Reflectance Index (SRI)2 of at least 29
- Open grid pavement system
Place a minimum of 25% of parking spaces under cover (defined as under ground, under deck, under roof, or under a building). Any roof used to shade or cover parking must have an SRI of at least 29.
