Cool Roofs and Walls to Reduce Heat Gain
Cool roofs reduce cooling energy but increase heating energy. The increase in heating energy is generally much less than one might think, however, as solar impact on roof and wall temperature is lower in winter than summer due to shorter days, lower intensity sunlight, lower solar angles, more cloudy days, and snow cover on roofs.
