At buildings such as hospitals, a co-generation system is used for heat efficiency improvement from the viewpoint of the vaild energy utilization. Therefore, the problem of sound and vibration is important in the neighborhood of the engine room, and a method of predicting the sound and vibration in the room is required. In this research, we adopt a building as the object of the research, and predict the sound and vibration at the neighbor room when dynamometer is operating in the general reinforced concrete building using the Statistical Energy Analysis (SEA) method. First, SEA model of the building is built, and power flow equations of the building are formulated. Next, to solve these equations, SEA parameters are calculated, and results of prediction of the sound and vibration showed a good agreement with sufficient accuracy in practical meaning.
