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.

*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 (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).

This measure applies to retrofit, new construction, and major renovation.

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

Apply now.  Submit required documentation:

• Copy of itemized invoice
• Project information form confirming the controls product appears on the qualifed products list

A Variable Frequency Drive (VFD) is a device that drives motors. When installed on a single-speed fan motor in an Air Handling Unit (AHU), it varies the speed of the fan to meet the needs of the system. VFDs can be used for AHUs that use either electric heat or gas heat, but must be a retrofit installation of an existing single-speed fan. Any existing AHU throttling or bypass devices (e.g. inlet guide vanes, dampers, etc.) must be removed or permanently disabled.

Connected thermostats save energy by controlling HVAC usage in single-zone HVAC systems. These thermostats connect to the internet and have features that include online alerts, monitoring and programming and/or control. Energy savings are associated with reduced heating and fan energy, primarily through scheduled temperature setbacks and setting the fan to auto mode during unoccupied hours.

This program is available for retrofits only. Lodging, 24/7 occupancy or semi-conditioned spaces do not qualify. The connected thermostat product must meet the following specifications:

• Capable of being connected to the web.
• Support multiple temperature set-back schedules.
• Support fan-mode scheduling (continuous-on versus auto mode).
• Support limited-duration overrides (e.g. reverts to programming after 24 hours).
• Automatically restore programmed settings after power outage.
• Support multiple cooling stages.
• Must be listed on Connected Thermostat Qualified Products List (QPL)

Package Terminal Heat Pump (PTHP) units are a convenient, all-in-one heating and cooling solution. 

PTHP's provide the majority of their heating and cooling output using energy-efficient reverse cycle technology.  Heat pumps use about 1/3 less electricity than standard air conditioning and heating. 

This measure is eligible to be installed in either:

• Lodging facilities which includes hotel, motel, bed and breakfast, dormitory, and shelter or;
• Residential care buildings which include nursing homes, retirement homes, and assisted living facilities.
• No other building types are allowed. 

Requirements and specifications:

• The space is conditioned by a PTAC or zonal electric-resistance heat as the primary heating source. No other heating soures are eligible. 

Apply now.  Submit required documentation:

• Copy of itemized invoice
• AHRI certificate

This measure applies to both retrofits and new construction. 

This measure calculates energy savings based on the Efficient Pumps Calculator less than or equal to 200 HP. The PEI is defined by a pump’s energy rating divided by an established baseline energy rating. The lower the PEI for a particular pump the more energy efficient it is.

There are five allowable pump types, in both 1,800 rpm and 3,600 rpm speeds:

• End suction, frame mount
• End suction, close-coupled
• In-line
• Radially split, multistage, vertical, in-line diffuser casing
• Submersible turbine

Apply now.  Submit required documentation:

• Copy of itemized invoice showing cost, manufacturer, model number, and size
• Copy of “NEW” Pump manufactures spec-sheet with a rated PEI number.
• Submit a completed Efficient Pumps Calculator(Excel file)

This measure applies to both commercial and industrial retrofit and new construction.

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.

Apply now.  Submit required documentation:

• 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.

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.

Apply Now. This measure applies to both retrofit and new construction. You must submit a demand-controlled kitchen ventilation program information form with your application.
