A window into energy savings
Windows are more than a way for sunlight to enter your home; they can be an easy way to lose valuable heat in the winter or cooling during the summer.
You can get a rebate of 50 cents per square foot — up to $300 — when you install qualifying high efficiency windows. Keep your home comfortable and save money!
Benefits of energy-efficient windows
- Get the light you need without uncomfortable heat
- Protect your valuables from fading or discoloration
- Save energy and money every month

Proof of SHGC and U-factor compliance should include independent third-party documentation such as NFRC labels or manufacturers' technical specifications.
- The following are required for payment of incentive:
- Complete incentive application

Learn more about energy-efficient windows
Whether you would like to improve the energy performance of your existing windows or replace them with new energy-efficient windows, here are definitions for common product terms you may encounter:
- U-Factor refers to the rate of heat loss; the lower the U-factor, the greater a window's resistance to heat flow and the better its insulating value
- Solar Heat Gain Coefficient (SHGC) is the fraction of incident solar radiation admitted through a window; the lower the SHGC, the less solar heat it transmits
- Visible Transmittance (VT) tallies to the amount of visible light transmitted; the higher the VT, the more light is transmitted.
- Air Leakage (AL) is the amount of air passing through a square foot of window area (cfm/sf); the lower the AL, the less air will pass through cracks in the assembly.
- Condensation Resistance (CR) measures how well a window resists the formation of condensation on the inside surface; the higher the number, the better.
Recommendations in the Southern Zone: A low SHGC is the most important window property in warm climates. A low U-factor is useful but it is less important than SHGC in warm climates.
