Abstract

This study sets up a zone-construction combination by constructing walls based on the classification of climates classified according to Korea's energy saving design standards and the heat paring rate standard of the wall. There are four climatic divisions, C1, C2, S, and J, and we have used representative climate data for each climate. The target building was a residential apartment, which is the main residential type of large cities in Korea and the world. In the set combination, PCM of TES system is placed indoors, and applied PCM is n-hexadecane, n-heptadecane, n-octadecane with phase change temperature of 20-28 °C corresponding to room temperature standard. Each PCM is set at 0.1% to 0.9% of the area of the building. We used Energy Plus 8.7, a building energy simulation, and analyzed the energy saving and economic efficiency of the building. Saved energy was 2.71% on average and we were able to save up to 4.56%. In addition, we conducted an economic analysis, saving an average of 3.42% and saving up to 7.48%.
