The paper presents results of computational fluid dynamics simulations of pressure at external surfaces of a typical high-rise residential building in Hong Kong in order to comment on wind-driven ventilation inside the flats. The simulations used k - epsilon turbulence model, and two and three-dimensional model of the building. The results reveal that an optimal building orientation relative to the wind can be found; the windward flats possess the best cross-ventilation potential; in the investigated flats, location of windows and rooms is not adequate to maximize cross-ventilation potential and minimize spread of odour. The new building plan provides better cross-ventilation. (C) 2004 Elsevier Ltd. All rights reserved.
