How Much Does Energy Star Roof Save

According to epa about 40 billion is spent annually in the us to air condition buildings one sixth of all electricity generated in a year.

How much does energy star roof save.

The most energy efficient roofs also have high emittance which means they re efficient at releasing any solar heat they have absorbed. Saves money and energy. It serves as a barrier against rain snow hail wind branches and debris. Energy star recognizes cool roof products that reduce peak cooling demand by 10 to 15.

Energy savings good for the environment and your wallet metal is one of the most energy efficient roofing materials available and can save your home up to 40 in energy costs and provide excellent insulation during the winter. For energy star certification energy saving shingles must reflect at least 65 percent of solar radiation if installed on a low sloped roof or 25 percent if installed on a steep sloped roof. Why do metal roofs save energy. This is known as the albedo effect and many studies have documented significant energy savings from simply lightening the color of a roof.

The color of the shingles you choose for your build can have a significant impact on the building s energy efficiency. To obtain the energy star label steep slope products must have an initial solar reflectance of at least 0 25. One way to estimate how much energy you would save by installing a cool roof is by using the cool roof calculator. The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building.

Even just a small leak can cause significant problems in the home and an inefficient roof can create energy performance issues throughout the home. Cool roofs can save money several ways including energy savings rebates and incentives hvac equipment downsizing and extended roof lifetime. These materials can lower the surface temperature of a roof by as much as 50 f and can reduce peak demand on air conditioners by up to 15 percent. Energy star certified roof products reduce the amount of air conditioning needed in buildings and can reduce energy bills by up to 50 percent.

The secret to metal roofing s energy savings is in its variety of finishes. Attic temperatures can vary as much as 20 to 40 degrees f which in turn can reduce energy consumption by 20.
