Abstract
Traditional architecture in hot climates has long recognized that reflective roof colors can potentially reduce thermal building load. Recent experiments at the Florida Solar Energy Center using small scale roof models, has shown the importance of roof reflectivity in reducing heat gain. However, until now, no tests have been available to show how roof reflectivity can influence cooling loads in occupied residential building in a cooling-dominated climate. To meet this need, FSEC has examined the impact of reflective roof coatings in air conditioning in a series of tests on sub-metered homes in Central Florida.
