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.

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. 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.

Thermal Emittance - an overview | ScienceDirect Topics

Solar reflectance of new white single-ply roofing membranes typically exceeds 0.70 (Akbari, 1998). Thermal emittance values of nonmetallic surfaces are generally between 0.80 and 0.90. Shiny metal roofs can have a relatively high solar reflectance, upwards of 0.60, but they tend to have low thermal emittances, which can make them as hot as dark roofs.
