solar reflectance index in the built environment - designing buildings wiki
the solar reflectance index (sri) is a measure of the solar reflectance and emissivity of materials that can be used as an indicator of how hot they are likely to become when solar radiation is incident on their surface. the lower the sri the hotter a material is likely to become in the sunshine.

what is a solar reflectance? - definition from corrosionpedia
solar reflectance is quantified by the solar reflective index (sri) which uses a scale from 0 to around 100. the lower the number the lower the amount of solar reflectance that a material has and therefore it will absorb more solar energy.
solar reflective index (sri) - corrosionpedia
the solar reflective index (sri) is a measure of the solar radiation that is reflected back by a rooftop surface (or any other surface in question) and the emissivity of the surface. it is an indicator of how hot the surface will become when the sun's radiation falls directly on it.
solar reflectivity (r) & solar reflectance index (sri) by color – dean ...
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 reflectance.
