In predicting flow rate of a cross-ventilated building, the conventional method using the discharge coefficient obtained from the chamber method and the wind pressure coefficient from a sealed model could underestimation. Authors aim to establish the prediction method of flow rate based on power balance within the stream tube inside and outside the building. In this paper, focusing the flow around the building, velocity, static pressure, and total pressure distribution will be shown by using PIV and rotatable to measure total/static pressure. In addition, those experiments are simulated by CFD because of its strength in determining the stream tube. In the last part of this paper, accuracy of CFD analyses will be shown.
