SA = (Solar Absorptance) is a measure of how much of the sun’s heat a material absorbs. These are nominal values based on new product and measured in acordance with ASTM E 903-96. Data provided by BlueScope Steel and Selection Steel.
SRI = (Solar Reflectance Index) assesses a surface’s capacity to reflect solar energy and stay cool. It merges solar reflectance and thermal emittance, producing a rating from 0 to 100. Higher SRI values signify surfaces that absorb less heat, aiding in mitigating urban heat islands, cutting cooling energy usage, and promoting environmental sustainability in construction.
