To reduce heat islands and minimize the impacts on microclimates and human and wildlife habitat
Non-Roof - Place at least 50% of parking spaces under cover (underground, under deck, under roof, under a building).
Any roof used to shade or cover parking must have an Solar Reflectance Index (SRI) of at least 29, be a vegetated green roof, or be covered by solar panels
that produce energy used to offset some non-renewable resource use
Roof - For a minimum of 75% of the roof surface, use roofing materials with an SRI equal to
or greater than a) 78 for a low-sloped roof (slope <=2:12), or b) 29 for a steep-sloped roof (slope >2:12)
