Managing Clean Air and Carbon Reduction from Open Loop Ground Source Heat Pump Systems: Two Case Studies

This presentation discusses the response to clean air and carbon reduction targets through the management of open loop ground source heat pump systems on urban groundwater resources. Two case studies from Galicia, Spain and Cornwall, UK are presented, highlighting the impacts, groundwater mounding, and projected groundwater levels. The regulatory and financial considerations in both cities are also discussed.
