An Unlikely Pair - Cool Roof Rating Council

An example would be that the efficiency of a PV system frequently improves when it is placed above a cool roof. Because of their lighter color, cool roofs reflect sunlight (solar reflectance) and efficiently emit thermal radiation (thermal emittance). By cooling the roof and lessening heat transfer into the building, cool roofs

Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color

Solar Reflectivity (R) &. Solar Reflectance Index (SRI) by Color. Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total

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
