This measure is the installation of an inverter driven ductless heat pump (DHP) with HSPF 9.0 or greater in the main living area of a low- or mid-rise (5 or more units and 6 or less stories) multifamily unit with existing, permanently installed in-unit electric resistance heat.  The data to inform energy savings estimates are relatively sparse and provide little insight into the savings across heating zones.  Due to high uncertainty, this measure is set to planning with an associated research strategy.  The research could be completed through a billing analysis and site visit/survey or other methods that achieve the following objectives:

  1. Estimate unit-level savings across all three heating zones for DHPs installed in low and mid-rise multifamily buildings.
  2. Estimate savings separately for varying identifiers (as outlined in the strategy) such as single-head vs multi-head systems, low-rise vs mid-rise, renter vs owner, etc.
