WebSolar reflectance is measured on a scale of 0 to 1. For example, a surface that reflects 55% of sunlight has a solar reflectance of 0.55. Most dark roof materials reflect 5 to 20% of incoming sunlight, while light-colored roof materials typically reflect 55 to 90%. Solar reflectance has the biggest effect on keeping your roof cool in the sun. WebApr 6, 2024 · Solar reflectance index or solar reflectivity is the capability of a material to reflect solar energy from the surface of material back to the atmosphere. The value of the solar reflectance index varies from 0 to 1. If the material absorbs all solar energy the value of the solar reflectance index is 0 and if the material reflects all solar ...

WebOne way to measure how "cool" a roof can be is by calculating its Solar Reflectance Index (SRI). This index is calculated following ASTM Standard E1980-11 using a roof product's solar reflectance and thermal emittance values. The SRI calculation can also be used to estimate the surface temperature of the roof product under prescribed conditions.

WebTE is also measured from 0 to 1. The higher the value, the more heat the material emits. The third metric used to measure the performance of cool roof coverings is called the Solar Reflectance Index (SRI). This measure is calculated from the TSR and TE.
