Benefits of ENERGY STAR

  • Save money — and more.

    Installing ENERGY STAR qualified windows, doors, and skylights lowers energy bills and saves you money. With more efficient windows, you also use less energy, which reduces greenhouse gas emissions from power plants. Feel your carbon footprint shrinking?

  • Get comfortable.

    Put an end to cold drafts and overheated spaces. ENERGY STAR qualified windows, doors, and skylights keep your home’s temperature consistently comfortable. Even your loveseat right by the window can be cozy with ENERGY STAR.

  • Protect your valuables.

    Many ENERGY STAR qualified windows, doors, and skylights have a special coating on the glass that is like sunscreen for your house.

Save Money — and More. Choose ENERGY STAR Qualified Products.

Installing ENERGY STAR qualified windows, doors, and skylights shrinks energy bills — and carbon footprints — by about 7-15 percent compared to non-qualified products.

Your estimated savings will vary depending on current heating and cooling costs in your region.

For a typical home, choose ENERGY STAR and save:

$146–$501
and
1,147–3,839 pounds of CO2which is equivalent to 59 to 196 gallons of gasoline		 a year when replacing single-pane windows
$71–$247
and
692–2,825 pounds of CO2which is equivalent to 35 to 144
gallons of gasoline		 a year when replacing double-pane, clear glass windows

UPGRADE TO ENERGY STAR

ANNUAL SAVINGS1

This image shows the regional annual savings when upgrading to ENERGY STAR qualified windows from either single-pane or double-pane, clear glass windows. The source for these savings is the U.S. Department of Energy. Savings estimates based on an even mix of one- and two-story detached homes of 1700 or 2600 sq. ft. respectively, with 15% of their floor space in windows that are equally distributed across compass directions.
