In order to evaluate wind environmental influences for a target apartment complex nearby industrial complex areas, the scale-down model of target area was placed in a boundary layer wind tunnel and the velocity fields were measured using a PIV velocity field measurement technique for two main wind directions. For each experimental condition, 350 instantaneous velocity fields were obtained and ensemble-averaged to get the mean velocity field. Flow speed was decreased near ground and local velocity fluctuations were increased in the upper region due to presence of hills and buildings around the target area. Especially, for the wind blown from the industrial complex areas, since pollutants can be concentrated in the regions of flow separation and low-speed flow, the high-rise apartments should be arranged properly to reduce this problem.
