Ground-Source Heat Pump Systems

Ground-source heat pump (GSHP) systems are an energy efficient technology for heating and cooling of non-residential buildings. Ground source is a relatively high and stable heat source tempe­rature that enables a considerable share of the cooling demand to be covered by means of so-called “free cooling”. Installation of high quality GSHP systems therefore complies with the main goals of the new EU Directive on The Energy Performance of Buildings (Directive 2002/91/EC), i.e. reduction of the total primary energy demand and the associated CO2 emissions in buildings.

The Norwegian contribution to the Annex 29 discusses the main characteristics of GSHP systems for heating and cooling of non-residential buildings in Norway including operational experiences. Several high-quality GSHP systems are presented, such as office buildings and a hospital. The hospital GSHP system is connec¬ted to one of the largest underground thermal energy storages in Europe comprising as many as 350 boreholes in crystalline rock.
