WebFundAmentAls oF solAr reFlectAnce Index (srI) The metric associated with the heat island concept is known as Solar Reflectance Index (SRI). Defined by the Cool Roof Rating Council (CRRC)b, SRI is calculated as “the ratio of the reflected flux to the incident flux.”1 Essentially, it is the ability of a material to reject solar energy. WebHigh-Reflectance Roof Use roofing materials that have an SRI equal to or greater than the values in Table 1. If aged SRI is not available, the roofing material shall have an initial SRI …

High Sierra Technologies, Inc.'s … WebRoofs that are lighter in color or are reflective stay cooler than roofs that absorb sunlight. There are two ways to help cool a roof. First, a cool roof can reflect away sunlight, so it stays cooler. Such a roof is said to have a high solar reflectance. Second, a cool roof should also release or emit heat (infrared radiation) so it stays cool. north berwick post office hours
