Outdoor Wind Environment Study of High-Rise Residential Buildings in Urban Areas

Harry Yi He - 2017

As the wind environment is one of the key elements in the sustainable and environmental design, there is a need to study local wind environments of modern cities. In urban areas, especially when the density of the city is increasing, the influence from buildings to wind environment is becoming higher and higher. This paper presents a literature review for the outdoor wind environment study of high‐rise residential buildings in urban areas. First, the previous wind environment research is reviewed. It not only helps to understand the fundamentals of the interaction of how wind flows around objects such as buildings on the earth’s surface but also present the gap between the formal study and the nowadays contemporary residential buildings in urban areas. Second, as there are two methods of wind tunnel and computational fluid dynamics (CFD) for simulating the wind environment, this paper focuses in summarizing the existing CFD tools and setting up the fundamentals for developing future workflow. Third, the evaluation criteria of the wind environment from different standards is compared. In the end, a possible framework to evaluate wind environment is discussed. The literature review is intended to highlight the limitations of previous research of novel high‐rise residential buildings and current adaptation analysis methods. In particular, for the hot‐summer and cold‐winter climate, and with the development of architecture, novel forms and arrangements of residential buildings have been developed, wind environment design strategy response to this kind of climate and forms is insufficient. The review helps to set up the fundamentals for our following research to explore the optimization of outdoor wind environment of residential buildings in urban areas by establishing early‐stage design principles
