Estimating your Rebate
Below is a step by step process one can use to estimate the rebate they could expect from installing ENERGY STAR® qualified windows in their home. Rebate program participants should note that the climate zones used to determine the ENERGY STAR rebate amounts in $/kWh are different from those used by ENERGY STAR to define rebate program eligibility. To determine eligibility, participants should first determine what U-factor and SHGC values are required for their zone. They should then consult the rebate map (seen in the Step 2) to determine their rebate amount.
Step 1: Select your Energy Zone region to determine rebate eligibility.
To be eligible, windows must have efficiency characteristics at or below those listed for your region.
| Region | Maximum U-Factor | Maximum SHGC |
| North-Central | 0.32 | 0.40 |
| South-Central | 0.35 | 0.30 |
| Southern | 0.60 | 0.24 |
Step 2: Select your climate zone by county to determine rebate amount.

Step 3: Calculate your rebate using the table
Once the climate zone and cooling/heating equipment is known, use Tables BA.2 to estimate the potential rebate. For example, a 3 by 5 ft. window meeting the ENERGY STAR® criteria in Climate Zone 1 (Amarillo, Potter County) that uses electric resistance heating could qualify for a rebate of $27.30. A 300 ft2 installation would qualify for as much as $546.00.
Example of 15 sq. ft. window (3’ x 5’): 1.82 $/sq.ft. x 15 sq.ft. = $27.30
| Table BA.2 * | Rebate | Rebate | Rebate |
| For Residential Program | Dollars | Dollars | Dollars |
| per sq. ft. | per sq. ft. | per sq. ft. | |
| Based on kWh | Based on kW | Total | |
| Climate Zone 1: Panhandle Region | |||
| Installed in home with non-electric heating (Gas) | $0.25 | $0.92 | $1.17 |
| Installed in home with electric resistance heating | $0.90 | $0.92 | $1.82 |
| Installed in home with heat pump | $0.65 | $0.92 | $1.57 |
| Climate Zone 2: North Region | |||
| Installed in home with non-electric heating (Gas) | $0.33 | $0.78 | $1.11 |
| Installed in home with electric resistance heating | $0.65 | $0.78 | $1.43 |
| Installed in home with heat pump | $0.50 | $0.78 | $1.28 |
| Climate Zone 3: South Region | |||
| Installed in home with non-electric heating (Gas) | $0.36 | $0.67 | $1.03 |

| Installed in home with heat pump | $0.51 | $0.75 | $1.26 |
If you are installing an energy efficient window in a commercial building, please contact your local utility to determine how an incentive amount should be calculated.
