Energy Star Windows
Energy Star ratings are often used to market housing materials, but many homeowners may not totally understand what they mean. You may not be convinced that Energy Star ratings make a difference. Here’s a quick overview of the Energy Star program and how it can help you increase savings and decrease your carbon footprint.
How do windows earn Energy Star ratings?
Energy Star is a voluntary program, formed jointly by the U.S. Environmental Protection Agency (EPA) and the Department of Energy, by which products can be rated for energy-efficiency. Energy Star ratings can be given to residential appliances, lighting, doors, and windows.
Under the program, qualified windows and doors must be manufactured by an Energy Star partner, independently tested and verified by the National Fenestration Rating Council (NFRC), and have NFRC ratings that meet EPA energy-efficiency guidelines.
Windows that earn Energy Star ratings have certain features, which may include:
- Multiple panes, often with spacers that reduce heat transfer
- Higher quality frame materials
- Special glass coating that reflect more light
- Gas fills between double panes to improve insulation
What do Energy Star windows mean for homeowners?
According to the Energy Star website, homeowners can save $101-$583 a year when they replace single-pane windows with Energy Star-rated windows. This also saves 1,006-6,205 pounds of CO2, or the equivalent of between 51 and 317 gallons of gasoline.
Individual savings depend on many factors, such as the products you choose and the climate you live in. For example, Baltimore is located in the North-Central Climate Zone. In this zone, Energy Star windows must have a U-factor of 0.28 or less. (U-factor measures the amount of heat transfer a window allows)
Besides reducing energy usage and costs, Energy Star windows also make a home more comfortable. The interior pane of glass stays warmer, keeping the area near the window from getting too cold. They also let in less heat during the summer.
