Abstract	Air movement in workplaces, whether resulting from a forced ventilation system or natural airflow, has a significant impact on occupational health. In a huge building of shipbuilding factory, typical harmful factors such as fume or vaporized gas from welding and cutting of steel plates give an unpleasant feeling. From field data survey, the yearly dominant wind directions around the factory building tested were north-west, north-east and south-east. Among the three wind directions, the ventilation improvement was the worst for the north-eastern wind. This study was focused on modification of opening vents in order to utilize the natural ventilation flow effectively. Instantaneous velocity fields inside the 1/1000 scale-down factory building model were measured using a 2-frame cross-correlation PIV method. The factory model was embedded in an atmospheric boundary layer simulated in a wind tunnel. The modified vents improved the internal ventilation flow with increasing the flow speed more than two times, compared with that of present vents.
