In a recent study, a cost-competitive reflective roof membrane reduced the average summertime daily maximum roof-surface temperature of a retail store in Austin, Texas, from 168°F (76°C) to 126°F (52°C). The total air-conditioning energy use was thereby reduced by 11% and peak air-conditioning demand fell by 14%. This 100,000-ft² building is predicted to save about $65,000 over the life of the roof.
