Each year, Energy Trust reviews incentives for cost effectiveness. We also add new incentives during this annual process. The following updates apply to Energy Trust Existing Buildings, greenhouses and New Buildings projects in Southwest Washington, and unless otherwise noted, will go into effect on January 1, 2020. Incentives which are not included in the list below will remain unchanged on January 1, 2020. These updates do not apply to other Energy Trust programs.
| Measure | 2019 Incentive | 2020 Incentive | Details |
|---|---|---|---|
| Existing Buildings | |||
| Commercial Condensing HVAC Boiler (New) | N/A | $3.25/kBtu/h input | Minimum 94% efficiency (either AFUE or thermal efficiency). Redundant, lagging or backup boilers do not qualify. Boilers used for DHW or pool heating do not qualify. Boilers, also known as “heat adders,” serving the water loops in water-source heat pump systems do not qualify. Boiler system design return temperature must be appropriate to condensing functionality. Cannot be combined with the Modulating Boiler Burner measure. |
| Modulating Boiler Burner | $2/kBtu/h input | $5/kBtu/h of burner rated capacity | Installed on a natural gas-fired boiler used for space heating. Boilers used for process heating, DHW or pool heating are not eligible. 5-to-1 turndown ratio or higher. Replacement of a dual stage burner or an on-off burner. Cannot be combined with the Commercial Condensing HVAC Boiler measure. |
| Commercial Condensing Pool Heater (New) | N/A | $2.35–$3.50/sq ft of pool surface area served by heater | Replacement of a gas-fired pool heater with capacity ≥ 350 kBtu/h. Minimum 96% thermal efficiency. Covered pools and spas are not eligible. |
| Bathroom Faucet Aerators | $3 each | $2 each | ≤ 0.5 GPM. Minimum 15 purchased per site. Gas water heating. |
| Commercial Vent Hood with DCV (New) | N/A | $750/controlled motor hp | Motor speeds must be controlled by a programmable controller, with scheduling, occupancy sensing, and heat sensing capabilities. Variable speed control must be installed on both the make-up air unit motor and the hood exhaust motor. Make up air must be tempered. Retrofit hp must not exceed total existing hp of makeup air unit and exhaust fan motor. Gas-heated spaces. |
| Attic insulation | $0.60/sq ft | $0.60/sq ft | No existing insulation, unless existing is damaged or missing. Damaged or missing insulation must be prequalified and documented by the installation contractor. Insulate to at least R-25 efficiency rating. |
| Roof Insulation | $0.60/sq ft | $0.50-$1.00/sq ft | No existing insulation, unless existing is damaged or missing. Damaged or missing insulation must be prequalified and documented by the installation contractor. Insulate to at least R-15 or R-30 efficiency rating. |
| Roof Insulation | $0.30/sq ft | $1.00/sq ft | Existing insulation is R-5 or less. Insulate to at least R-30 efficiency rating. |
| Wall Insulation | $0.60/sq ft | $0.60/sq ft | No existing insulation. Insulate to at least R-20 efficiency rating. |
| Pipe Insulation | $2–$6/lineal ft | $4–$12/lineal ft | No existing insulation. Jacketing that provides an appropriate level of protection for the insulation under the given environmental conditions to maintain the life of the insulation. This will commonly be All Service Jacketing (ASJ) or PVC in indoor applications and aluminum or stainless steel jacketing for outdoor projects. Pipe diameter ≤ 1.5” will insulate to at least 1.5” thickness. Pipe diameter > 1.5” will insulate to at least 2” thickness. Piping must be part of a system using natural gas. |
| Greenhouses | |||
| Thermal Curtains | $0.30/sq ft | $1.17/sq ft of conditioned floor space | |
| Infrared Polyethylene Greenhouse Film | $0.32/sq ft | $0.10/sq ft | |
| Under-bench Heating | $1.05/sq ft | $2.19/sq ft | |
| New Buildings | |||
| Commercial Hot Water Condensing Boiler, Space Heating | $8–$10/kBtu/h input | Discontinued | |
| Commercial Condensing HVAC Boiler (New) | N/A | $0.02/sq ft | Minimum 94% efficiency (either AFUE or thermal efficiency). Load to be served by HVAC boiler must meet the 94% efficiency requirement. Redundant, lagging or backup boilers do not qualify. Must verify area (sq ft) served by the boiler. Boilers used for DHW or pool heating do not qualify. Boilers, also known as “heat adders,” serving the water loops in water-source heat pump systems are not eligible. Boiler system design return temperature must be appropriate to condensing functionality. |
| Bathroom Faucet Aerator (New) | N/A | $2 each | ≤ 0.5 GPM. Minimum 15 purchased per site. Gas water heating. |
| Kitchen Faucet Aerator (New) | N/A | $5 each | ≤ 1.5 GPM. Minimum 15 purchased per site. Gas water heating. |
| Add Doors to Open Refrigerated Cases | $100/linear ft of door | Discontinued | |
