The objective of this work is to analyse dissipation and transportation of energy inside stream tubes passing through/around a crossventilated building, which is not sufficiently known and is required for an establishment of an improved prediction method of flow rate for wind induced cross-ventilation. This paper focuses on velocity and pressure distribution around a building because it is to be analysed to evaluate the energy loss due to divergence and confluence of the stream tubes. Although this can be done by using CFD, they must also be clarified by measurement in advance to verify the accuracy of CFD afterwards. First, velocity distribution is shown by using Particle Image Velocimetry (PIV). To measure spatial static pressure, a five-hole pitot tube is used. This device can provide three flow quantities simultaneously, i.e., static pressure, velocity magnitude, and wind direction. By comparing results between measurement and CFD conducted in the previous work, this paper finally presents both accuracy of CFD around building model and the scope of each experimental technique.
