1/6/2017 SS CREDIT 5 Roof Measures HEAT ISLAND REDUCTION ROOF MEASURES Use three-year aged SRI value from Table 1 (if not available then use Initial SRI) >2:12 SRI 39/32* <2:12 SRI 82/64* * 3-year aged SRi/initial SRi SS CREDIT 5 HEAT ISLAND REDUCTION SOLAR REFLECTANCE The fraction of solar energy (light) that is reflected by a (SR) surface on a scale of 0 to 1. THERMAL EMITTANCE Ability of a material to shed infrared radiation (heat). Values (TE) between 0 and 100% SOLAR REFLECTANCE A measure of a constructed surface’s ability to stay cool in INDEX (SRI) the sun - High SR and TE. How to get values… - SR and TE values from the CRRC-1 www.coolroofs.com - ASTM E 1980 gives SRI calculations, and there’s an app for that too! - Manufacturer’s are making products to meet the LEED requirements, and publishing data. 15
