Impact Effects of Traditional Settlement Spaces on the Wind Environment in Hot and Humid Regions with Gentle Airflow
An integrated analysis of the impact of traditional settlement spaces in regions characterized by a mild and humid climate on the wind environment is conducted.Field investigations are utilized alongside Computational Fluid Dynamics(CFD)software to simulate and analyze the wind environment of the overall settlement and individual buildings within the settlement.Specifically,three typical courtyard houses in Fengtai Village are selected for analysis,exploring the influence of different length-to-height and width-to-height ratios on the wind environment of the settlement.Considering the combined effects of the overall street and alley structure and building density within the settlement,the winter wind speed in Fengtai Village exhibits a general distribution pattern of being higher in the northeast and lower in the southwest,while in summer,the wind speed within the settlement shows an increasing trend from the village entrance towards the northeast direction,indicating a generally favorable wind environment within the settlement.Simulation analysis yields the optimal spatial configuration for the courtyard houses,with a width-to-height ratio of 6 and a length-to-height ratio of 7.2.The wind environment within the settlement is influenced by a combination of street and alley structures,prevailing seasonal winds,and building morphology and density.Traditional settlement spatial configurations demonstrate efficient adaptation to regional wind environments and effective utilization of local microclimate conditions.It is recommended that this spatial shape should be followed in the future settlement protection planning and regional architectural design to ensure optimal settlement environments.
