Effects of building configuration on ventilation performance of naturally-ventilated building

![CDATA[For wind-induced natural ventilation, a surrounding building’s effect on a target building and the target building’s envelopes are two main factors to affect the indoor air flow characteristics. There are few research works studying the effect of surrounding buildings on indoor natural ventilation. In this work, Computational Fluid Dynamics (CFD) method was employed to model 18 different cases to invesigate numerically the effect of an upstream building with two different heights to the target building with two different types of wing walls under two different wind directions (a wind incidence angle α=0° and α=45°). The results show the target building generally has a better natural ventilation performance when the wind obliquely incidents on the building. In addition, the ventilation performance of wing walls is highly dependent on the environment including the approaching wind directions, the orientation of the target building and height of the upstream building.]]
