The ratio of the total amount of radiation, as of light, reflected by a surface to the total amount of radiation incident on the surface.

reflectance

reflection factor

n
(Units) a measure of the ability of a surface to reflect light or other electromagnetic radiation, equal to the ratio of the reflected flux to the incident flux. Symbol: ρ Compare transmittance, absorptance

These methods determine the reflectance coefficient by fitting the measured reflectance distribution to the BSSRDF, a rendering model that takes into account optical characteristics [10].
A white membrane roof was chosen to reduce the heat island effect; the material has a high reflectance coefficient, which greatly reduces the overall heating and cooling load requirements for the building.
