The purpose of this study is to show the validity of applying the Geothermal Seasonal Cooling Storage System considering the characteristic of climate of Seoul. The results were as follows. (1) By analyzing the characteristics of the climate of Seoul region, the composition of the system that stored the low-temperature energy in the winter and utilized in the summer was proposed. (2) It was confirmed that the thermal storage efficiency of the system reached 78%. (3) It was shown that the energy consumption of the system was 66% lower than that of Geothermal Heat Pump System.

The purpose of this study is to show the method of applying snow thermal storage system through the analysis of the cases in Japan. The results were as follows. (1) The systems in Japan were installed at the location whose annual mean air temperature was 14.6 ℃ or below and annual snowfall was 59 cm or above. (2) By analyzing the characteristics of the systems, meltwater circulation system with a backup chiller was confirmed to be most suitable for Korea. (3) For the first time in Korea, the system with the snow storage of 500 ton was designed at Muju after analyzing regional climate characteristics.

The purpose of this paper is to show a simplified annual cooling load calculation method that HVAC system designer can use in early design stage for the realization of zero energy building and to clarify the error range of the method in a office building. This method was a simplified method related to the RTS method but could calculate the cooling loads of 8,760 hours, because weather data and operating schedule were added in RTS method. In a case study, the results by this method was 9% of MBEmonth , 26% of MBEhour compared with the load value calculated by EnergyPlus program.
