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


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.
