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 with an existing zonal or forced-air electric-resistance heating system.

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.

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).

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 existing zonal or forced-air electric-resistance heating system with a split or packaged air-source heat pump.

Upgrade/new construction: Replaces an existing split or packaged air-source heat pump with a more efficient air-source heat pump or adds an air-source heat pump to a new construction building (includes additions and major building renovation).

Retrofit, non-electric heat: 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.

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

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. These thermostats connect to the internet and have features that include online alerts, monitoring, programming, and controls. Scheduled temperature setbacks, remote operation, and setting the fan to auto mode during unoccupied hours are some of the ways connected thermostats lower your heating, cooling, and fan energy use.

Connected thermostats must replace an existing single zone thermostat that is not web-enabled. Multiple rebates may be available at a single location. Lodging, 24/7 occupancy, semi-conditioned spaces, and new construction installations do not qualify. Connected thermostats that are part of an ARC rebate (see above) are not eligible for an additional rebate.

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.  You can print a paper application here.  You can email the following required documents to ems.answers@eweb.org:

• Copy of itemized invoice
• AHRI certificate

This measure applies to both retrofits and new construction.
