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:

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.
