Studies Show Reflective Roofing Materials Reduce Cooling Energy Use
Two studies highlight advances in roofing materials that reduce cooling energy use. A 1995 Florida study showed that coating a school roof white cut chiller energy use by 10% and peak demand by 35%. Separately, researchers at City University of Hong Kong developed a ceramic tile reflecting 99.6% of sunlight, lowering surface temperatures by about 5°C and potentially reducing cooling electricity by over 20%. While white roofs save energy in warm climates, they may increase heating costs in colder areas. Commercial adoption faces challenges including production and building codes.
