“…However, mitigating the impacts of the building layout and establishing ventilation corridors are only two of the many considerations toward eco-city construction. Further research should be conducted on the relationship between the urban wind environment (UWE) and urban building energy (UBE), in order to reduce energy consumption from the perspective of UWE impact [22]; therefore, urban climates and living conditions may be greatly improved with science-based planning and constructions.…”

“…Therefore, we considered the differences in the vegetation height estimation method. The forest vegetation height was obtained from the global vegetation height data with a resolution of 1000 m, while the crop height was acquired from observations from the Shijiazhuang Agro-Meteorological Station [22]. In summary, the surface roughness length with a resolution of 25 m suburban areas in Shijiazhuang was obtained.…”

The rapid development of urbanization has caused obstructed urban natural ventilation and the contribution rate of urbanization is relatively high. Therefore, there is an urgent need for urban development planning that should respect natural ventilation and local climate to reduce negative impacts. By optimizing the urban construction layout to reduce obstruction and leave a passageway for wind to blow in, the natural ventilation environment could be improved. This paper presents a promising approach for natural ventilation planning at both the city and community scales. Based on the assessment of wind environment, heat island intensity, and ventilation potential, the results revealed that winds blowing from the western and northern mountainous area of Shijiazhuang play a natural ventilation inlet role which can provide clean air. The SSHI and SHI were mainly distributed within the Second Ring Road, which has a large proportion of the low ventilation potential level. Thus, six first-class ventilation corridors and thirteen secondary corridors were recommended, which were set to be adapted to the dominant wind direction. Subsequently, an urban climate analysis map (UCAnMap) was developed considering climate sensitivity, and planning recommendations were provided for different climate zones. The relationship between architectural spatial structure and ventilation efficiency was analyzed; the results revealed that increasing the height of the buildings will decrease the proportion of comfortable wind zones, and the overall ventilation efficiency will weaken, so the average building height of a typical block should be controlled within 45 m, which matches ventilation performance requirements. The ventilation efficiency of the block has a certain negative correlation with the building density, and as the building density decreased by more than 10%, the proportion of the comfortable wind zones could increase by 4–5%.

“…Jie et al provided a comprehensive review of the impact mechanisms of urban wind environments on urban building energy consumption, addressing a gap in the existing literature by examining building-scale and city-scale simulation tools and proposing future directions to enhance accuracy and validation methods in energy consumption calculations considering urban wind environments [13]. Oh et al developed a novel approach utilizing building-resolved large-eddy simulation (LES) to analyze the thermal wind environment in urban areas with high-rise buildings, incorporating seasonal atmospheric data and validating the method against wind tunnel experiments, showcasing the occurrence of downdraft winds and large-circulation induced by high-rise buildings, which significantly influence pedestrian-level temperatures and urban thermal environments [14].…”

The wind catchment effect and sheltering effect were also explored within this context [13].…”

Although T-form buildings have been widely observed in newly constructed high-rise residential communities, there have been relatively limited investigations into the influence of their geometries on wind environments. This study aims to address this gap by conducting iterative quantitative assessments of the influences of various bulge-part sizes of typical T-form high-rise residential buildings on surrounding wind environments. A methodology has been employed by integrating multiple computational tools, including parametric modeling, Computational Fluid Dynamics (CFD), and Influenced Areas (IAs) analysis. Representative T-form buildings have been modeled with parametric components, allowing for easy variation of bulge-part sizes. The investigation process involves sequential steps of parametric modeling, experimentally validated CFD simulations, statistical assessment, and subsequent results analysis and discussions. Findings could be summarized as follows: (1) according to IAs analysis, the influences on wind environments were decreased as the bulge-part sizes were increased, and the decrease of the bulge-part sizes could cause the contrary effect; (2) the promotion of outdoor ventilation caused by the increase of the bulge-part length was more than the increase of the bulge-part width according to the correlation coefficients (0.88 > 0.78; 0.88 > 0.76); (3) it was recommended to design relatively large bulge parts on the windward side to enhance outdoor ventilation. The research outcomes provide valuable and insightful information for the development of sustainable architectural design strategies aimed at optimizing natural ventilation.
