HEAT ISLAND EFFECT REDUCTION (NON-ROOF)

CRITERIA FOR QUALIFICATION One point of credit is available for implementing any one of the following sets of practices: ? Incorporate light-colored materials in at least 50% of the site’s impervious area (e.g., walkways, driveways, plazas, and parking areas), excluding the building footprint. The material must have a solar reflectance greater than 0.3 or a Solar Reflectance Index (SRI) greater than 29%. Uncolored concrete with or without any proportion of fly ash and/or slag may be assumed to have a solar reflectance of 0.3 or SRI of 29%. Design and install overhangs, shading elements, trees, and shrubs (or preserve existing trees and shrubs) to shade at least 50% of sidewalks, patios, and driveways within 50 feet of the house (based on noon on June 21 at 15 years’ growth). Covered parking (underground, parking garage, or under overhands/awnings/roof) roofs or exposed podium patio must have a solar reflectance greater than 0.3 or an SRI greater than 29%. Uncolored concrete with or without any proportion of fly ash and/or slag may be assumed to have a solar reflectance of 0.3 or SRI of 29%.
