Abstract

The purpose of this study was to investigate the effects of voids in tall buildings on the surrounding wind environment. With the development of modular technology, there has been a new method of building high-rise buildings. Currently, more and more high-rise buildings often use void spaces to reduce the wind resistance and utilize wind turbines by using wind power to create sky gardens. In this study, CFD (computer fluid dynamic) technology was used to simulate the wind environment around the buildings. The research focuses on the size, distribution and quantity of the concavity, which usually is defined as sky gardens. It is found that when the area of the opening is the same, the more number of opening, the more strengthened and distributed vertical wind velocity behind the building can be. The wind shadow area at the pedestrian height is further reduced. For holes distribution, the optimum ratio of the spacing between concavities to the void size for wind environment of tall buildings ranges from 1 to 3, which can disperse the surrounding heat in more efficiency and weaken the wind velocity in the lowest level. Therefore, in high-rise buildings, the number and distribution of the openings will have different effects on the wind environment around the buildings.
