With our constant focus on providing the right blend of energy efficiency programs for customers, we are rolling out some changes in November. While new energy efficiency incentive programs will be offered, this program is ending Nov. 1. If you are currently participating in this program, please complete and submit your application before Nov. 30.

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

Eligibility requirements

  • Offer is available to Gulf Power residential customers only.
  • Offer is limited to one rebate application per calendar year.
  • Application must be made within 60 days of installation of qualifying products.
  • Qualifying products must be installed on exterior walls and adjacent to conditioned space.
  • Products must meet the most current ENERGY STAR® guidelines for the Southern Climate Zone; or they must be certified by the National Fenestration Rating Council (NFRC) to possess a solar heat gain coefficient (SHGC) of less than or equal to 0.25 and a U-factor that is less than or equal to 0.4. 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
    • Documentation of proof of equipment qualifications (including manufacturer and the appropriate efficiency specifications of the equipment)
    • Sales receipt documentation including date of installation
  • Installation must pass Gulf Power’s verification process.

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.
