Rebates over $2,500 require pre-approval by EWEB before installation. Prior to granting approval, we must receive your rebate application. For more information, please email us at ems.answers@eweb.org or call 541-685-7088.
Keep your employees and customers comfortable throughout the year and reduce energy waste by installing insulation and high-performance windows. Use our rebates or low-interest loans to help with the cost.
Windows
The building must have primarily electric heat and have pre-existing single-pane, single-pane with storms, or double-pane metal-frame windows. This rebate applies to retrofits only. Rebates not available for new construction.
Rebate requirements: Replacement windows must have a U-factor of 0.30 or less, based on National Fenestration Rating Council (NFRC) ratings.
Loan requirements: Replacement windows must have a U-factor of 0.30 or less.
The following window installations do not qualify: replacing pre-existing double-pane wood or vinyl windows, converting a flat window to a "garden window", window size enlargements (unless for egress purposes), or replacing windows in unheated spaces.
Apply now. Submit required documentation:
- Copy of itemized invoice
- Proof of U-factors needs to be provided using either the manufacturer's order confirmation showing the sizes and U-factors for all windows, or the NFRC sticker from each window
- Project information form

Rebate per sq ft of glass |

| WIN100 | Windows in a building with an air-source heat pump | $9 |
| WIN110 | Windows in a building with electric zonal or electric forced air furnace | $9 |
Secondary Windows
Secondary windows are sometimes referred to window inserts, secondary glazing systems, or window retrofit panels. The base case used to calculate energy efficiency savings for secondary windows is a commercial building with single-pane, clear glass, low-performance windows. The efficient case used to calculate savings requires the installation of laminated or insulated glass interior window attachments with low-E coating on double-lite (IGU) glass. This measure doesn’t require replacing the existing glass or window frames, and generally doesn’t alter the existing window aesthetics (i.e., historic buildings) or exterior appearance of the building.
Pre-conditions:
- Existing windows must be single-pane glass
- The building’s primary heat source must be electric (e.g., zonal, VAV with electric reheat, or heat pump)
Post-conditions:
- Have one or more low-E coatings resulting in an overall solar heat gain coefficient, (SHGCOverall) of 0.55 or less, and
- Have a center-of-glass U-factor (UCOG) less than or equal to 0.20
Apply now. Submit required documentation:
- Copy of itemized invoice
- Product Specification Sheet that documents SHGC and U-factor

Insulation
The building must have primarily electric heat and have no more than R-5 pre-existing insulation in the ceiling or walls. This rebate applies to retrofits only. Rebates not available for new construction.
Rebate and loan requirements: Each attic/roof needs to be insulated to at least R-19, and walls need to be insulated to at least R-11. Please notify EWEB of the installation time so we can do an in-progress inspection.
Rebates and loans are not available for floor insulation.

Get Started!
As we transition to a new customer information and billing system, we have temporarily paused program applications. We will begin accepting new applications in early December when we have transitioned to our new systems.
We appreciate your patience and apologize for any inconvenience this may cause. Please do not hesitate to reach out if you have any questions or concerns. EWEB staff will still be available to answer all questions regarding our efficiency and water conservation programs during this period.
