Abstract: Life cycle assessment (LCA) method was applied to assess the energy and environmental impact of ground source heat
pump and air source heat pump used in the same building. The results showed that ground source heat pump performs better in
six of the seven impact categories investigated, excepting ozone depletion potential (ODP), the energy and overall environmental
impact of ground source heat pump, evaluated by common weighting methods, are better than air source heat pump, and the most
dominant energy and environmental impact of both systems arise from the operating stage.

 Key words: ground source heat pump; air source heat pump; life cycle assessment
