The EPA introduced the Energy Star program in 1992 to help increase the energy efficiency of household products and appliances. Americans spend about $40 billion per year just on air conditioning, which represents about 1/6 of all the electricity produced. So the Energy Star program has been extended to cool roofing, which reduces the heat load on your air conditioner. Here’s a quote from EnergyStar.gov: ENERGY STAR qualified roof products can help reduce the amount of air conditioning needed in buildings, and can reduce peak cooling demand by 10-15 percent. Here’s a link to GAF’s market-leading residential cool shingle options and a link to commercial cool roofing options including our TPO roofing and Topcoat products.
