The purpose of this paper is to research the estimations of the indoor natural temperature in a case of the earth sheltered space and the 1st basement room in comparison with a conventional housing. The result of this study can be summerized as follows: The natural temperature of the earth sheltered house Summer : $${\theta}es=27.0+1.65sin(2{\pi}/24{\cdot}T-1.34)$$ Winter : $${\theta}ew=11.5+1.15sin(2{\pi}/24{\cdot}T-1.61)$$ The natural temperature of the 1st basement space Summer : $${\theta}us=25.5+1.00sin(2{\pi}/24{\cdot}T-1.72)$$ Winter : $${\theta}uw=13.9+1.10sin(2{\pi}/24{\cdot}T-2.29)$$ From the results of the stated above, we can calculate the cooling and heating load in the earth sheltered house and the underground space exactly and easily at Taejeon City.

The purpose of this paper is to research the performance of the thermal environment in summer in a case of the earth helmed house designed to be suitable for Korean situation in comparison with a conventional housing. The result of this study can be summerized as follows; 1) The indoor mean temperature of the earth bermed house is 1.3℃ lower than outdoor one within a period of measurement and that of a conventional housing is 0.4℃ higher than outdoor one, so the earth bermed housing has cooler indoor temperature in summer. 2) The time-lag of the earth bermed house is 40 minutes longer than that of a conventional housing, and the earth termed housing has better performance of retaining heat than the conventional housing. 3) The fluctuating ratio of indoor temperature in the earth bermed house is 0.46 smaller than the conventional housing. It means that the earth bermed housing has better idiosyncrasy of thermostatic mitigation than the conventional housing. 4) The relative humidity of an earth bermed house has 12.3 percentages more than a conventional housing. 5) The thermal environment of the earth helmed house except for the humidity in summer is proved to be more comfortable than that of a conventional housing according to the internal treatise. To improve the thermal environment of the earth helmed housing, the prevention of moisture should be investigated in the future.

Abstract The purpose .of this paper is to research the properties of the indoor natural temperature in a case of the earth sheltered house and the 1st basement room in comparison with a conventional housing. The result of this study can be summari- zed as follows: (1) The indoor natural temperature of the 1st basement space is influenced by the outside temperature rather than by the underground temperature. (2) The indoor natural temperature of the earth sheltered house and the 1st basement space can be estimated as follows from the harmonic analysis of the fluc- tuant curve of indoor natural temperature. The natural temperature of the earth sheltered House Summer : θes = 27.0 + 1.65 sin (2 /24. T - 1.34) Winter : <θew = 11.5 = 1.15 sin (2 /24. T - 1.61) The natural temperature of the 1st basement space Summer : <θus = 25.5 = 1.00 sin (2 /24. T - 1.72) Winter : ffuw = 13.9 + 1.10 sin (2 /24.T - 2.29) From the results of the stated above, we can calculate the cooling and heating load in the earth sheltered house and the underground space easily and Correctly at Taejeon City. The purpose of this paper is to research the properties of the indoor natural temperature in a case of the earth sheltered house and the 1st basement room in comparison with a conventional housing.

地中空間의 熱環境 特性에 關한 硏究(Ⅱ) : 熱傳達 特性을 中心으로 the Case of the Heat Transfer Characteristics
李時雄 大田工業大學 1991 한밭대학교 논문집 Vol.8 No.1
The purpose of this study is to find the heat transfer characteristics of the underground space. A model underground space was selected for measurement in Taejeon city, To grasp the distributions of thermal conditions, outdoor air temperature, ground temperature, and various points of indoor temperature were measured. The measurements were performed in two seasons ; summer(cooling period) and winter(heating period) under natural conditions in the model underground space. As a result the heat transfer characteristics of the underground space has the status of stabilization, the lower heating load and the similar heat transfer coefficient of the inside wall surface comparing to that of residential space.
