The performance of ground source heat pump system significantly depends on ground properties such as thermalconductivity, underground water level, quality of underground water and groundwater flow. Therefore, in order to optimally designsystem, it is necessary to estimate thermal properties before the system design. On the other hand, fundamental survey for systemdesign, such as thermal response test or pumping test, require cost more than 5,000 dollars. To simply consider GSHP systems as heatsource system in building design, it is necessary to roughly grasp the feasibility of the system in the step of building basic planning. Inthis research, sensitivity analysis of design factors was conducted to develop a suitable map for a ground source heat pump system inKorea. This paper mainly describes the effect of ground thermal properties on the system performance. Numerical simulations withground heat and groundwater transfer model was used for quantitative analysis. The result showed that thermal conductivity of soiland groundwater flow are very important factors and the differential of system performance according to them was a maximum of29%.
