Development of deemed energy and demand savings for residential ground-source heat pump retrofits...

Summary

Summarises work to develop savings estimates for geothermal heat pump retrofits in residential applications in the four major climatic regions of Texas.  Modelled the performance of a complete neighbourhood of 200 multifamily residences, comparing the annual energy consumption and peak demand of geothermal or ground-coupled heat pumps (GCHPs) and 10 air-source heat pumps.  Three different GCHP efficiency levels were modelled, and the systems were modelled both with and without de-superheaters to supplement domestic hot water tanks.
