Every year, energy efficiency ranks high on the list of must-haves for home buyers. 

A recent report, conducted by the National Association of Home Builders, showed that the top green features buyers are looking for in a new home are:

1. Energy Star-rated windows and appliances.
2. Efficient lighting that uses less energy than traditional light bulbs.
3. Energy Star rating for the whole house.

Fortunately, energy-efficient windows aren’t just for new construction. Installing Energy Star-rated windows is one of the easiest ways to reduce energy consumption, and in turn, lower monthly bills. 

What are energy-efficient windows?

Energy-efficient windows keep heat inside the home in the winter, and cool air in during the summer. The climate zone where you live determines the type of window that is qualified for your location. 

Energy Star windows are manufactured by an Energy Star partner, tested and certified by the National Fenestration Rating Council, and meet strict energy efficiency guidelines set by the US Environmental Protection Agency.

Criteria of an Energy-Efficient Window

To be considered energy efficient, they must have specific features. These include:

• Low-E Glass. A special coating on the windows helps to reflect infrared light and ultraviolet light. This not only increases the insulation but helps to protect your carpets and furniture against fading from the sun.
• Panes of Glass. Energy-efficient windows contain at least two panes of glass, but can have three or more panes for more insulation. 
• Warm Edge Spacers. Edge spacers keep the panes of glass secure at an equal distance apart. Warm edge spacers are non-metallic, helping to reduce the loss of heat around the edges of the window.
• Gas Fill. In between the panes of glass, non-toxic, odorless, and colorless gases can be added. These gases help increase insulation. 
  

Framing Options

In addition to creating the aesthetic style of the window, window frames are as important as glass when it comes to energy efficiency. The frames ensure there are no gaps between the window and the siding, so no air escapes. 

There are numerous options for Energy Star-rated window frames. All of these framing options are designed to provide optimal insulation:

• Wood 
• Fiberglass
• Vinyl
• Aluminum 
• Combination: Made of different materials, used separately throughout the frame (such as a wood interior and fiberglass exterior). 
• Composite: Manufactured with blended materials. 

We know how important it is to both reduce energy usage and keep the home comfortable. Selecting windows that are energy efficient is an easy way to accomplish both.
