Numerical simulation on natural ventilation in a real estate in high- density city
Natural ventilation is an efficient way to keep residential building safe and comfortable. In many high -density populated cities, to meet the housing demand of citizens, a large number of high -rise residential towers are being built. When buildings are closely sited, the influence of adjacent buildings on the availability of cross ventilation becomes a critical building design consideration. The paper reports on the results of CFD (Computational Fluid Dynamics) simulation studies on such effects based on a real estate in Hong Kong that comprised an array of building blocks. The result shows that cross ventilation in buildings downstream of other buildings would be much reduced, especially when the buildings were aligned facing the wind direction, and when the spaces between buildings were small. Shortening the upstream buildings and laying out the buildings in a staggered pattern would significantly improve cross ventilation in the downstream buildings.
