solar reflectance index roofing

Solar Reflectance Index in the built environment - Designing.

The US department of energy defines the Solar Reflectance Index (SRI.) as '…a measure of the roof's ability to reject solar heat as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05 emittance 0.90) is 0 and a standard white (reflectance 0.80 emittance 0.90) is 100.【Get Price】

What is Solar Reflective Index (SRI) and. - Roof Restoration

Solar Reflective Index (SRI) is important to understand when selecting a highly reflective roof coating that will help lower energy cooling costs. The SRI is a calculation method using solar reflectance and thermal emittance values to determine the roof's overall capacity to refuse solar heat.【Get Price】

SOLAR REFLECTANCE INDEX (SRI): Incorporates both solar reflectance and thermal emissivity in a single value. SRI measures the roof’s ability to reject solar heat defined such that a standard black (reflectance 0.05 emittance 0.90) is 0 and a standard white (reflectance 0.80 emittance 0.90) is 100.

Solar Reflectance Index: The Guide to Choosing a Cool Roof

What Is Solar Reflectance Index? The SRI is a measure of the roof's ability to repel solar heat as shown by a small temperature increase. It defines that the standard black is 0 which is most likely to absorb heat. The standard white is 100 which is most likely to reflect heat.【Get Price】
