Much more information is available about high performance windows from the Efficient Windows Collaborative and from the Energy Star Windows® program websites. TWI worked closely with both groups to develop our training program and we strongly recommend that Texans choose Energy Star® Window products for their homes. You can find out which manufacturers are participating in the Energy Star® program at the Energy Star® website.

The Efficient Windows website is loaded with helpful information about better windows and other energy saving strategies for the home. Many examples are shown for houses around the country and software is available to help builders and homeowners evaluate the energy performance of their homes.
