In this paper, characteristics of the indoor environment utilizing hybrid ventilation system andtask-ambient air-conditioning system are investigated every hour in a year in various types of office spaces by means of dynamic cooling and heating load analysis and CFD (Computational Fluid Dynamics) simulation.Authors had investigated the characteristics of the indoor environment of a hybrid ventilation system, utilizing natural and mechanical ventilation, with CFD simulation under various conditions of incoming outdoor air [1]. Furthermore, the effect of personal air-conditioning unit, which will be newly developed in our study and will cost lower than before, is considered in this study. It can satisfy the human thermal comfort without energy waste. The characteristics of unsteady human thermal adaptability will also analyzed in another study [2], [3]. With the database of characteristics of indoor environment, which will be gained in this study, most effective management methods of the air-conditioning system and ventilation system, which can ensure both energy saving and human thermal comfort, will be proposed. It will lead to energy saving control strategy for the building management system.
