Windows for Commercial Buildings

Replacing old windows with new energy-efficient windows can save energy and money, add to the comfort of employees and customers, and enhance the look and feel of your business.

Chelan PUD offers these incentives to businesses for upgrading to energy-efficient windows:

-  For buildings with electric resistance heat, up to $20 per square foot of installed windows.
-  For buildings with heat pumps, up to $10 per square foot of installed windows.

This incentive is available for retrofits only; new construction is not eligible.

Installations must have the following characteristics:

• Electrically heated
• A total floor area under 20,000 square feet
• Pre-existing windows that are single-pane, single-pane with storms, or double-pane metal-frame

The replacement windows must have a National Fenestration Rating Council rated U-value of 0.30 or lower.

To apply for the incentive, please submit to Chelan County PUD:
