Abstract
Wind tunnel experiments were conducted to study the relation between the air flow and the shape of buildings, concentrating on the location of the void space through which air can pass. The strong wind region near the ground becomes minimum when the distance from the ground to the bottom of the void space is nearly equal to the building width, in case that the building height is 2 to 5 times its width. As the location comes near the ground, the strong wind region increases rapidly.
