Window Replacement Program

Replacing existing windows with energy-efficient windows will help to reduce solar heat gain. To qualify for a rebate of $2.20 per square foot*, windows must be installed within conditioned space and be labeled by the National Fenestration Rating Council (NFRC) to have a minimum Solar Heat Gain Coefficient (SHGC) less than or equal to .35, and a U-factor less than or equal to .60. Windows installed within non-conditioned space, such as a garage or sun room, do not qualify for a rebate.

In addition, the existing structure must have electric whole-house air conditioning or heating. The rebate is based only on newly installed windows and sliding glass doors meeting the requirements above. After your window replacements are installed, you can proceed with acquiring your rebate.
