We propose a cooperated rotation method of office air conditioners for energy-saving to aim stability of the room temperature change. The proposed method determines the rotation schedule based on the air conditioners operation results for each zone and the results of the trend analysis of the room temperature. The reason for setting the rotation schedule in this way is that trends of the room temperature are different for each zone because of the ubiquity thermal load in the office building. In addition, the proposed method analyze the effect of rapid temperature change of zone is given to the other zones. Then, the proposed method adjusts the timing of rotation using this information so as to suppress a decrease in room temperature in the entire floor. In this paper, we developed a prototype that implements the proposed method in the real office building (about 500 square meters). And, we have conducted an experimental evaluation the target heating period (Mon 1-2).
