Study on the influence of voids on high-rise building on the wind environment

Li, Yangluxi; Chen, Lei

cavities in building could apparently improve pollutant dispersion condition behind architecture wherever the voids locating at the top or bottom of construction. For example, with regard to case C, the z/H range under 1.5 of CR value for case CU1 locates at 0.7, which is significantly larger than that of 0.5 for case CU3. This result distinctly shows that the pollutant condition is improved around the middle of building by increasing the opening discrete degree. It is an important conclusion, especially in view of sky court which increasingly occurs in the roof of high-rise building, the decomposed distribution for this air garden could effectively enhance the status of loss of pollutant dispersion in the middle of high-rise building.
