Solar reflective Index Testing for Historical Concrete Paving

Project Description

USA LABORATORY
Third Party Testing Facility needed for LEED SRI (Solar Reflective Index) testing for an exposed aggregate historical concrete paving in Chicago IL as Per the LEED guidebook:
SRI
A measure of the constructed surface's ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. It is defined such that a standard black surface (initial solar reflectance 0.05, initial thermal emittance 0.90) has an initial SRI of 0, and a standard white surface (initial solar reflectance 0.80, initial thermal emittance 0.90) has an initial SRI of 100. To calculate the SRI for a given material, obtain its solar reflectance and thermal emittance via the Cool Roof Rating Council Standard (CRRC-1). SRI is calculated according to ASTM E 1980. Calculation of the aged SRI is based on the aged tested values of solar reflectance and thermal emittance.
