In this study, we aim to provide experimental data required to validate Computational Fluid Dynamics (CFD) simulations of pollutant diffusion around buildings in non-isothermal flow. In order to obtain turbulent statistics including turbulent heat flux and turbulent concentration flux which are important quantities to evaluate turbulence models, we developed a simultaneous measurement system of fluctuating concentration, velocity and temperature. By using this measurement system, we measured wind velocity, temperature and concentration around a simple building simultaneously in non-isothermal flow. We examined mechanism of heat and concentration transfer in the flow fields. These reliable results will be available for the validation of CFD.
