Solar reflectance of roofing materials.

The solar reflectance index is used for compliance with leed. The larger these two values are the cooler the roof will remain in the sun. Requirements and is calculated according to astm e 1980 using values for reflectance and emissivity. It is defined so that a standard black surface reflectance 0 05 emittance 0 90 is 0 and a standard white surface reflectance 0 80 emittance 0 90 is 100.

The solar reflectance index sri is a measure of the constructed surface s ability to reflect solar heat as shown by a small temperature rise. The ages solar reflectance and thermal emittance requirements will vary depending on the slope of the roof climate zone and the density of the roofing product. Emissivity is a material s ability to release absorbed energy. Solar reflectance and thermal emittance are the two key material surface properties that determine a roof s temperature and they each range on a scale from 0 to 1.

The solar reflectance measurement ranges between 0 0 and 1 0 with 1 0 representing 100 reflectance with no absorption. Asphalt shingles with higher solar reflectance values can achieve energy star certification. To meet leed requirements a roofing material must have a sri of 29 or higher for steep slope 2 12 roofing and a sri value of 78 or higher for low slope roofing. Heat island effect roof.
