| description | In recent climate-adaptive design strategies, there has been a growing interest in creating healthy and comfortable urban microclimates. However, not enough attention has been paid to the influence of street interface morphology in order to better understand the wind–thermal conditions of various commercial streets within the city and create a sustainable built environment. This research summarizes and categorizes commercial streets according to their functions and types of attributes and then abstracts the ideal models of three types of typical commercial streets to explore the effects of changes in specific morphological parameters on their wind–thermal environments. Firstly, this study selects out design parameters that affect the street interface morphology. Then, it uses the numerical simulation software PHOENICS2019 to simulate and investigate the effects of three types of typical commercial street interface morphology on their wind environment and thermal comfort. The results show that (1) in neighborhood-commercial streets, reducing void ratio and variance of height fluctuations can enhance the average wind speed of the street while reducing average temperature and improving the thermal comfort; (2) in business-office streets, the value of the void ratio is negatively correlated with the wind environment and thermal comfort, while the changes in the variance of height fluctuations and the average aspect ratio are positively correlated; and (3) in comprehensive-commercial streets, the decrease of the void ratio will reduce the average wind speed of its street and increase the average temperature, thus weakening the thermal comfort of pedestrians. In contrast, the variance of height fluctuations as well as the average aspect ratio do not significantly affect its wind–thermal environment. These conclusions from this research provide a theoretical basis and methodological reference for the creation of safer, resilient and sustainable built environments. |
