DHP Multi-Family Billing Analyses for Side by Side Comparison of Energy Use for Electric Resistance Heat and DHPs

Multifamily (MF) is hugely underserved in Residential energy efficiency (EE) Programs and part of our MF ductless heat pump (DHP) strategy is to look at different MF use cases and identify which MF use cases provide a higher EE potential. So far DHP results in MF are mixed and this project will assess the energy use and savings of ductless heat pumps in mid-rise MF buildings. This study offers a unique opportunity for a side by side comparison of heat pumps and electric resistance heat within a single apartment building with 278 apartments. The project would collect billing data on all the individual units, conduct an analysis to disaggregate heating, cooling, and baseload energy use, and compare the two types of heating systems.
