Use Ceiling Light Reflectance to Save Energy

Did you know that the ceiling you choose can affect your energy costs?
In order to make sure it lowers energy use, choose a ceiling panel with a high light reflectance rating. Those panels can reflect daylight back into a space, lessening the need for artificial lighting.
Light reflectance is measured on a scale of 1-3. LR-1 rated panels reflect the most daylight back into a space — 75 percent or more. LR-2 and LR-3 rated panels do not reflect as much light and may not be suited for spaces where daylight maximization is a goal.
