http://www.vanderbilt.eu/docs/Trebla_Services_Emissie_Tabel.pdf WebSolar 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.

Web2 jul. 2024 · Solar reflectivity refers to how well a material reflects solar energy - sending this energy back into the environment. Low or non-reflective materials will absorb the solar energy, which causes the material to heat up. Roofing materials can have an SR (solar reflectivity) value from 0 up to 1.0. WebIt can be seen, that reflectivity of the perfectly smooth metal surfaces is generally higher in the MWIR than in the visible spectrum, and it converges to 1 with the increasing …
