REFLECTANCE

The fraction of incident radiation (usually the visible spectrum of sunlight) that is scattered (i.e., not absorbed or transmitted) by a surface. Reflectance is expressed as a number between 0 and 1 or as a percentage between 0% and 100%. Cool roofs and reflective coatings have high reflectance values.
