Abstract

The high population density and mountainous terrain in Hong Kong create many challenges in its urban development and supply of residential housing. The buildings tend to go vertical and high density to maximize the use of land. However, this kind of development causes environmental problems and health hazard due to low level of ventilation. To understand ventilation problems in complex situation, like an urban area, the fundamental fluid dynamics of simple building geometries and configurations, such as single building, parallel buildings, building clusters and street canyon, may not be directly applicable. Computational fluid dynamics (CFD) could be an effective and efficient tool to visualize and study the fluid dynamics in complex environment. This article discusses how the advanced simulation tool could be applied to understand the wind environment and identify ventilation problems in building designs. This is a very important process as generation of an innovative and sustainable ventilation design is based on the fundamental understanding of the current constraint and problem; and testing of the design concept in response to the constraint and problem. The article presents an urban wind environment and a natural ventilation study. The innovative strategies proposed in the studies may also be applicable to other cases with similar ventilation issues.
