요약2 Recently, the most widely used geothermal application field is heating and cooling, and ground source heat pumps are recognized as a good alternative to the heating and cooling of buildings. The purpose of this study is to investigate the reason of the error and the method to reduce the difference by comparing and analyzing the data obtained from the simulation data of the target building where the ground source heat pump is applied. This study focused on reducing the error rate through EWT correction which has the greatest effect on the ground source heat pump. EWT is the temperature of the inlet tube at which the heat transfer medium enters the heat exchanger of the heat pump, and is affected by the geothermal environment. Correction of the input value through EMS reduced the length of the borehole which affects most of the underground heat exchanger by about 9%. The flow rate is corrected by an average of 3%, and the hole spacing is corrected by about 2.8%, and finally the thermal conductivity is corrected by about 2%.
