The effectiveness and financial viability of a ground-source heat pump (GSHP) system heavily rely on the heating and cooling demands of a target building and the properties of the ground. The objective of this study was to design a hypothetical GSHP system for a daycare center building. Based on the design results, the performance of the GSHP system was assessed through EnergyPlus simulation, and the simulation results were compared with the performance of the existing HVAC system. In addition, a simple method was proposed to evaluate the potential of the GSHP system using public data and GIS information. To verify the reliability of the potential calculation results, they were compared with the simulation design results. The simulation results of the existing system (System-A) for the target building revealed a discrepancy of -6.32% in the actual electricity consumption and a discrepancy of 7.88% in the gas consumption. The annual energy consumption of the hypothetical GSHP system (System-B) is 59.5 MWh (82.5 kWh/m²year), and the source energy consumption per building unit area is evaluated as 222.8 kWh/m²year. In comparison to the actual usage (System-A, 395.7 kWh/m²year), the System-B was calculated to result in a 43.7% reduction in primary energy consumption on an annual basis. The available land area for vertical ground heat exchanger installation was potentially evaluated to be 451 m², which exceeds the simulation result of 250 m². Therefore, the target building is deemed to possess sufficient ground heat exchanger capacity. Based on the potential evaluation, considering the ground source heat pump capacity and COP, the target building requires 8 boreholes for the ground heat exchanger, which is the same result as the design program result.
