Energy performance ratings for windows provide insight into a product's ability to acquire and expend heat. As reported by Energy Star and Energy.gov, the National Fenestration Rating Council (NFRC) is an independent organization that provides information regarding the efficiency not only of windows, but also of doors and skylights.

Some of the factors involved in obtaining Energy Star certification include:
- U-Factors provide heat transfer rates and advise how well a window insulates.
- Solar heat gain coefficient rates how well a window blocks sunlight.
- Visible transmittance measures how much light a window will allow through it.
- Air leakage measures rates of leakage through window joints.
- Condensation resistance calculates how well a window resists water build-up.
For double-pane windows, look for ones with a U-Factor that is 0.30 or lower. If it is a triple-pane window, then you can go as low as 0.15. These numbers vary based on the region you reside.
In order to obtain true energy efficiency, precise installation is required. The correct method of installation is dependent upon a number of variables, including:
- Window type.
- Home construction materials.
- Home exterior siding.
- Type of weather-restrictive barrier.
Consumers who are interested in quality windows should contact a contractor about the best windows for their home and consider a warranty if they need to install multiple windows.
Like many Americans, cost is a big factor when it comes to window prices. If you are unable to invest in new windows, there are cost-saving measures you can undertake, such as:
- Storm windows can decrease the movement of air in and out of your windows.
- Caulking to seal air leaks in cracks and gaps around windows.
- Weather stripping to seal off air leaks for movable objects like window or doors.
- Window treatments including awnings, drapes and blinds decrease heat in your home.
- Window coverings, such as shades and shutters, assist in keeping your home cool.
