Energy Star Roof Products Program


Reflective Roof Products Can Save Money and the Environment.

The U.S.Environmental Protection Agency (EPA) announced the Energy Star Roof Products Program Charter Partner companies at the National Roofing Contractors Association Convention (NRCA) in Phoenix, Arizona, on February 9, 1999. As of February 21, 2000, a total of 112 roof product manufacturers have joined the program.
What is ENERGY STAR?
In EPA's new ENERGY STAR Roof Products Program, manufacturers will be allowed to use the ENERGY STAR label on reflective roof products that meet EPA's specifications for solar reflectance and reliability.

The ENERGY STAR label, which was designed by EPA and the Department of Energy (DOE) to help consumers easily identify energy-efficient products, is already used on a variety of products, including heating and cooling (HVAC) systems, household appliances, office equipment, insulation and even homes.
Saving the earth, saving you money
According to EPA, approximately $40 billion is spent annually in the U.S. to air condition buildings - using one sixth of all electricity generated in the country each year. However, reflective ENERGY STAR-labeled roof products can reduce the amount of air conditioning needed to cool these buildings by preventing the sun's heat from entering them, thereby reducing energy bills by up to 50%. In fact, reflective roofs can lower roof surface temperature by up to 100 degrees Fahrenheit. They can also reduce peak cooling demand by 10 to 15 percent, enabling building owners to buy smaller, less expensive HVAC systems. The extent of savings depends on a number of factors including climate, insulation levels and type of roof installed.

ENERGY STAR-labeled roof products benefit the environment because, in the U.S., most of the energy needed to cool buildings is created by burning fossil fuels, a process which releases pollutants into the air. Consequently, by decreasing the nation's energy needs, reflective roof products will decrease the amount of air pollution produced by power plants.

ENERGY STAR-labeled roof products can also help reduce the "heat island effect", a phenomenon in which dark, heat absorbing buildings and paved areas make the air in urban areas as much as 8 degrees hotter than surrounding communities. By reducing the "heat island effect", these products also help reduce smog levels and the associated heat- and smog- related health problems.

EPA anticipates that roofing manufacturers and contractors will want to market ENERGY STAR-labeled products because they offer "increased value to customers".
