This measure is the installation of an AHRI certified Packaged Terminal Heat Pump (PTHP) in either a lodging or residential care building type. This applies to retrofits of working PTACs with integral electric resistance heat, retrofits of PTACs at the end of their useful life, or in new construction. Due to the lack of field research into the performance of PTHPs, this is an engineering analysis relying on EnergyPlus modeling using lodging and residential care models that have been aligned to CBSA data. Due to the high uncertainty, this measure has been set to planning with an associated research strategy. The research could be completed through a market study and billing analysis or other methods that achieve the following objectives: 1. Estimate the relative sales percent of PTACs and PTHPs by state for the Pacific northwest 2. Estimate the savings rate separately for varying identifiers (as outlined in the research strategy) such as by building type, heating zone, PTHP size, unit operation, etc.
