“…Cons: Less accurate compared to std. − k ε model for low wind speed region due to underestimation of TKE in the wake region [17] RNG − k ε [65][66][67][68] Pros: For high wind speed region, accuracy improves as compared to std. − k ε model.…”

“…This is the wind field around buildings at a height of 1.5-2 m above ground, which affects the comfort of walking and standing pedestrians. Building configuration (e.g., height, width, arrangement, and density) has been shown to have a strong influence on wind at the ground level (Mochida & Lun, 2008;Shia et al, 2015). Wind speed affects pedestrian comfort and wind safety.…”

During the initial developmental stage of historical settlement, residents used the principles of feng shui to locate suitable residence sites to ensure quality of life. Using Huazhai Village in Taiwan as a case study, this study explores the design philosophy of ancient Chinese people through scientific analysis. Research showed that the region was characterized by a windy climate. Therefore, a computational fluid dynamics model was used to simulate the local wind environment and restore the early architectural complex of the village. Compared to the current situation, it was demonstrated that the planning principles of the early buildings gave first priority to site selection. Second, with the village streets acting as a wind corridor, the angle of the streets was well utilized to strengthen outdoor ventilation in summer. Third, according to wind field characteristics at different locations, various opening directions and arrangement modes were applied in different areas to improve the wind field of the living environment. This ancient ecological wisdom provides current designers with a new strategy for living in harmony with nature, which may aid the design of sustainable living environments that adapt to the climate.

“…A research proposed that window design parameters, such as window size and position, should be modified to improve indoor thermal comfort. Xing Shi et al [15] demonstrated the application of the wind environment assessment method by using an actual case of urban planning as an example. The evaluation criteria included wind comfort, wind safety, and wind amplification factor.…”

With the rapid urbanization and expansion of construction demands in China, the continuously increasing density of residential buildings has led to outdoor pedestrian discomfort in residential wind environment. To analyze the relationship between residential building density and wind environment, simulation cases of residential buildings with different building densities were presented in this study. First, the wind environment characteristics of residential districts with different building densities were established via computer numerical simulation. Second, wind speed ratio (WSR) and age of air (AA) distribution were calculated at pedestrian height. Finally, the quantitative relationship between residential outdoor wind environment and building density was proposed. Results demonstrate a negative linear correlation between the building density and outdoor mean wind speed ratio (MWSR) of residential districts and a positive linear relationship between building density and mean age of air (MAA). When residential building density increased from 0.18 to 0.32, the MWSR in the district decreased by 0.18, whereas MAA increased by 58.63 s. As residential building density increases, the WSR within the residential district decreases and the age of air (AA) increases, which affect the outdoor comfort of residents. This study provides references for improving the wind environment of high-density residential districts and for optimizing residential layout planning.
