정수일(Jeong, sooill) 한국주거학회 2002 한국주거학회 논문집 Vol.13 No.4
In Gumi area, the heating and cooling loads for underground building could have not been correctly evaluated since there were no systems accurate underground temperature. For solving this problem two ways of predicting the underground temperature were propose. Firstly, it is to estimate the underground temperature of Gumi area by averaging out the underground temperature of the areas around Gumi city. However, the underground temperature data of the areas around Gumi city was only limited to 0.5m and 1.0m under the ground. Secondly, it is to calculate the underground temperature of Gumi area by using a periodic equation with variable about underground properties. Among these methods, the method of the average date was more correct, but the method of the variable date was more available.

Korea gets most of its housing energy from fossil fuel which can be mined only for 30 years. So the development of an alternative energy is very important. Solar and underground thermal energy are two of these alternatives but little study has been conducted on these. For use of underground energy, we need accurate data regarding underground temperature, but there are only 30 measuring points for underground temperature in the entire country. We need to have a method of predicting underground temperature precisely. In this study the underground temperature is measured at under 3m in Gumi, and these data are compared with predicted data for checking the accuracy of the predicting method.
