The objective of this study is to examine the environmental characteristics of the floor thermal storage system which was applied to an office building in Kobe and an test building in Fukuoka in order to balance the electric power demand and provide a comfortable thermal environment.According to the field measurments of the office building in summer and the experiments with the test building in winter, this system reduces running cost by utilization of the nighttime discount power rate and the radiation from the floor and ceiling surface contributes to maintaining space thermal comfort for the occupants.In addition, Simulations of this system were carried out to clarify the thermal characteristics and the energy consumption. The sensible heat extraction rate of the air-conditioning system with floor thermal storage is larger than the standard air-conditioning system by 5% but the electric power rate of the floor thermal storage airconditioning system is smaller than that of the standard system to the extent of 30%.

为了平衡电力需求并提供舒适的热环境，本研究以科比办公大楼及福冈实验大楼为对象，探讨地板蓄热系统的环境特性，并根据办公大楼夏季的实地量测及实验大楼冬季的实验结果，该系统利用夜间折扣电价降低了运行成本，地板和天花板表面的辐射有助于保持空间的热舒适性，并对该系统进行了仿真，以阐明该系统的热特性和能耗。地板蓄热空调系统的显热提取率比标准空调系统高5%，而电功率比标准空调系统低30%。
