In order to investigate the optimum locations for the installation of ground-coupled heat pump system, heat exchange rate maps in the Fukui Plain were developed. For the estimation of the heat exchange performance at difference location in the plain, a single ground heat exchanger (GHE) model was constructed. The results of the field-wide groundwater flow-heat transfer modeling by Uchida et al. (2010), such as local hydraulic head and the distribution of subsurface temperature, were used as the boundary and initial conditions of the single GHE model. And then, the heat exchange rates in the cases of the snow melting and the air conditioning were estimated at 13 locations in the plain. The developed ground heat exchange rate maps using the results from the single GHE models were compared with the geological, hydrological and thermal information of the plain. As the result, the geological information (the rate of sand gravel layer thickness) was successfully linked with the ground heat exchange rate maps.
