N2 - The thermal energy storage (TES) is an energy storage method implemented to reduce the heating energy consumption of buildings by utilizing a high-efficiency heating system and a TES system. Therefore, in this study, a TES system is applied to a high-efficient floor heating system. Various methods are available to utilize the sensible heat and latent heat for TES, and a phase change material (PCM) that can store the latent heat is used in this study. The PCM is used in the form of a heat storage sheet. The physical property analysis results show that the phase change interval of the PCM was 17–32 °C, the latent heat amount was 40.39 J/g, and the specific heat was 1.5 J/(g K). The dynamic heat analysis confirmed the peak temperature rise during heating, and the maximum value at the surface was 1.04 °C. In addition, during cooling, a cooling delay time of up to 5 h was observed due to the heat storage effect of the PCM. Therefore, it is possible to store thermal energy by using a material called PCM, and the saved heat energy can reduce the heating energy requirement of buildings.
