Task ambient air conditioning system with natural ventilation for high rise office building (Part 2 : measurement of natural ventilation rate and CFD analysis using measured data)

For the part 2 of that study, detailed measurements of natural ventilation rate were conducted in a high rise office building in Osaka while twenty natural ventilation openings were kept open. Then natural ventilation rate was calculated for sixteen outside wind directions using wind pressure coefficients obtained by wind tunnel tests. A CFD analysis using the measured data as the boundary condition, reproduced the detailed airflow pattern in the whole office room.
