Ductless Heat Pumps
Ductless Heat Pumps, also called DHPs or mini-splits, save energy using inverter-driven variable speed compressors continuously matching the heating and cooling load. DHPs are two to three times more efficient than electric-resistance heaters. DHPs do not use integrated electric back-up heat. DHPs are most suitable for small commercial buildings such as offices, warehouses, restaurants, and retail spaces. They may include short duct runs or they may be ductless.
Retrofit, electric heat: Installing a DHP in a building that is currently heated by a permanently installed system with zonal or forced-air, electric resistance heat as the primary heating source.
Upgrade/new construction: Replacing an existing DHP with a more efficient DHP system or adding a DHP to a new construction building, an addition, or as part of a major building renovation.
Retrofit, non-electric heat: Installing a DHP in a building that is currently heated by non-electric heat.
*DHP Upgrade measure can be claimed for a project that also claims the DHP Retrofit measure, as long as all applicable pre- and post-conditions are met. $1300/ton.
The following documents are required to be sumitted prior to distribution of rebate:
- Copy of itemized invoice to include make, model and manufacturer.

These measures cannot be used to retrofit Packaged Terminal Air Condition (PTAC) units.
Split or Packaged Air-source Heat Pumps
A split heat pump system has an indoor air handler and a separate outdoor compressor. A packaged heat pump system has both the heating and cooling equipment in a single "package" that's located outside a building, typically on the roof.
Retrofit, electric heat: Replaces the permanently installed primary heating source of zonal or forced-air electric-resistance heat with a split or packaged air-source heat pump.
Upgrade/new construction: Must meet efficiencies by capacity in the table below. The ASHP Upgrade measure may be used for any project where the post-condition requirements are met including new construction/major renovation projects, retrofits replacing existing heat pumps, retrofits replacing equipment using a fuel source other than electric, and retrofits that qualify for the ASHP Retrofit measure.
Retrofit, non-electric heat: Must meet efficiencies by capacity in the table below. A split or packaged air-source heat pump is installed in a commercial area of a building that is currently heated by non-electric heat.
*The ASHP Upgrade measure can be claimed for a project that also claims the ASHP Retrofit measure, if all applicable pre- and post-conditions are met and meet BPA's efficiency requirements per the table below.

Variable Refrigerant Flow Heat Pumps (VRF)
Variable Refrigerant Flow (VRF) heat pumps have similar applications as Ductless Heat Pumps (DHP), though they are more commonly used for multi-zone commercial HVAC applications and are available in larger tonnages. A VRF system cools or heats a space more efficiently than standard systems by moving variable amounts of refrigerant through a piping system to each space. The primary advantage of VRF is the ability to simultaneously heat and cool different spaces, with even greater efficiency. However, VRFs do not deliver ventilation air and are often combined with ventilation systems such as an Energy Recovery Ventilator (ERV) or a Dedicated Outdoor Air System (DOAS).
The following documents are required to be sumitted prior to distribution of rebate:
- Copy of itemized invoice to include make, model, and manufacturer.
- AHRI certificate showing the system meets EWEB efficiency requirements for heating. Table below.
- Project information form
EWEB Code | Existing System | New System | Rebate |
---|---|---|---|
VRF-110 | Retrofit (Electric Resistance Heat) | VRF (single and multi-head) | $1,000 per ton of cooling capacity |
VRF-120 | Retrofit (non-electric/gas heat) | VRF (single and multi-head) | $350 per ton of cooling capacity |
We also offer VRF incentives on a custom basis for new construction/major renovation, and large or complex VRF projects. Please see Custom Projects for more details.
Heat Recovery Ventilation Equipment
Heat Recovery is a method often employed on commercial buildings to recover heat from building exhaust and use it to pre-heat incoming supply air. Heat Recovery units can be a stand-alone device or integrated directly into HVAC equipment and are commonly located on rooftops or in mechanical penthouses.
The following documents are required to be sumitted prior to distribution of rebate:
- Copy of itemized invoice to include make, model, and manufacturer.
- Report from manufacturer selection software showing selected model number and Sensible Rated Effectiveness (SRE) at 75% of rated airflow.
HRV Retrofit:
- The space is conditioned by an operational or failed heat pump, or electric-resistance heater as the primary heating source. No other heating sources are eligible.
- The existing system does not have a heat recovery device installed.
- The existing system is designed to provide ventilation air currently.
HRV Upgrade:
- The space is part of a building addition, new construction or major renovation (i.e., baseboard electric-resistance heating to VRF with ventilation, etc.) project.
- Projects completed in Washington State are not eligible, due to code requirements.
Post-condition:
- The installed heat recovery unit must utilize manufacturer selection software and demonstrate a minimum 70% SRE at 75% of rated airflow for Tier 1, or a minimum 82% SRE at 75% of rated airflow for Tier 2.

HtRec -200 | Electric | Tier 2 unit with ≥82% SRE | $3.50 |
Advanced Rooftop Unit Control (ARC)
Advanced rooftop control (ARC) retrofits can cost-effectively improve the energy performance of HVAC Rooftop Units (RTUs). ARC retrofits can reduce fan speeds up to 40% during the first stage of heating and cooling and 60% when no heating or cooling is needed. "ARC-Lite" saves fan energy by modulating fan speeds to meet demand. A second type of retrofit, "ARC-Full", can save additional energy by incorporating integrated economizer control and demand controlled ventilation. ARC retrofits are recommended for systems with at least 5 years of remaining life.
The existing RTU must have the following characteristics:
- Be a packaged unitary equipment (no split systems)
- Have a minimum of five tons of cooling capacity
- Constant speed supply fan (no variable speed fans)
- Heating can be provided by gas or electricity
ARC-Lite products must add one of the following options to the existing RTU:
- A VFD and controller for variable speed fan operation
- A multispeed motor and controller for multispeed fan operation
ARC-Full products must additionally include:
- Digital, integrated economizer control
- Web enabled control, monitoring and alarms
- Demand control ventilation, based on CO2 sensor reading
The following documents are required to be sumitted prior to distribution of rebate:
- Copy of itemized invoice
- Project information form confirming the controls product appears on the qualifed products list
EWEB Code | Product | Rebate Per Ton |

Variable Frequency Drive for Pumps
A variable frequency drive (VFD) on a commercial or industrial pump that is less than or equal to 100 HP, adds a VFD on a single speed pump in a system that has either a constant or variable load. The pump may be used for a variety of systems, such as, but not limited to chilled water, condenser water, heating hot water, domestic hot water, municipal water or wastewater, etc.
With this technology, the VFD varies the speed of the pump to meet the conditions of the system. As the pump motor slows down, it draws less power than at constant speed, resulting in energy savings.
The following documents are required to be sumitted prior to distribution of rebate:
- Copy of itemized invoice showing cost, manufacturer, model number, type and size installed.
Pre-conditions:
- Existing VFD must be installed on a commercial or industrial single-speed pump that is less than or equal to 100 HP.
- The system can be either a constant or variable load.
Post-conditions:
- The retrofit adds a VFD to control the pump with variable-speed operation.
- Any existing pump throttling (i.e., flow control valve, etc.) or bypass devices (i.e., 3-way valves, etc.) must be removed or permanently disabled.
This measure applies to both commercial and industrial retrofit and new construction.
Not applicable for agriculture/irrigation pumps.
Code | Existing System | New System | Rebate per Horsepower |
---|---|---|---|
VFD Pump - 100 | Electric or gas | VFD | $180 |
Demand-Controlled Kitchen Ventilation
Demand-Controlled Kitchen Ventilation (DCKV) automatically reduces kitchen hood and make-up air fan speed during times of low activity or demand. Energy savings are achieved as a result of reduced fan power and reduced make-up air heating requirements.
- For existing applications, the ventilation system has a constant-speed exhaust fan.
- For new construction applications, there are no preconditions.
The demand-controlled kitchen ventilation equipment:
- Controls the primary ventilation and make-up air units in the zone.
- Utilitizes one or more control sensors to modify the fan speeds.
This measure applies to both retrofit and new construction. You must submit a demand-controlled kitchen ventilation program information form with your application.
