Climate change resulting from the increase of greenhouse gases became a global agenda, also it is an important issue in our daily life in many aspects. It was reported that the average ambient temperature of Korea has been increased by about 1.5°C for the last 100 years. This pattern of climate change will also affect the shallow-depth geothermal energy utilization for space heating and cooling.

In this study, ‘degree days’ were used as an indicator to estimate heating and cooling demand from the outdoor temperature variation. The calculated degree days were compared to the electricity consumption of the ground source heat pump (GSHP) system installed and monitored in the study area. From the correlation analysis, the base temperature for degree days calculation was determined.

Based upon the base temperature, heating and cooling degree days were calculated using the climatic data from 60 weather stations in Korea. The calculated values were used to analyze spatial and temporal variations in the heat demand for buildings. The weather files from Representative Concentration Pathway (RCP) Scenarios were also analyzed to predict the future energy demand according to anthropogenic greenhouse gas (GHG) emissions.
