WebJul 12, 2024 · The Solar Reflectance Index (SRI) is an indicator of the ability of a roof surface to return solar energy to the atmosphere. Roofing material surfaces with a higher SRI will be cooler than surfaces with a lower SRI under the same solar energy exposure, especially on a sunny day. WebMar 3, 2024 · The laboratory tests are primarily focused to understand the properties of new materials, while field tests assess the performance and durability of the material. “Solar reflectance index” is an approach to determine a single value incorporating both solar reflectance and thermal emittance.
