Programme Highlight:

With rapid progress of urban development, modern mega-cities are teeming with tall and closely spaced buildings, which subsequently results in congested airflow at pedestrian level. This issue is more serious in the subtropical urban area, like Hong Kong. Thus, to represent weak wind condition in Hong Kong, a new wind comfort criterion was proposed by thoroughly reviewing and comparing existing wind comfort criteria. The adopted parameters were carefully chosen to adapt the weak wind conditions. To improve the weak wind condition, the effects of lift-up design on wind comfort have been investigated comprehensively. Quality and efficiency of CFD simulation on pedestrian level wind environment in a complex urban area are often compromised by many influencing factors, particularly mesh quality. Thus, the CFD simulation of a geometrically complex campus has been conducted based on a high-quality structural mesh system. The work was fully supported by a grant from the Research Grants Council of the Hong Kong Special Administrative Region, China (Project No. C5002-14G).
