solar reflectivity index composite deck

Urban Heat Island Reduction, SRI - Concrete Thinker.A composite index called the solar reflectance index (SRI) is used by the U.S. Green Building Council and others to estimate how hot a surface will get when exposed to full sun. The temperature of a surface depends on the surface's reflectance and emittance, as well as solar radiation. The Solar Reflectance Index (SRI) is.
