“…In terms of wind environment, Shaeri et al used CFD software to simulate the outdoor thermal environment of traditional blocks in Iran. The results showed that the wind speed ratios of open spaces and lane entrances are higher than those of other places [49]. The simulation results of Hu et al indicated that when the residential BD increases from 0.18 to 0.32, the mean wind speed ratio of the residential area decreases by 0.18 [50].…”

Rapid urbanization has caused environmental problems such as the urban heat island and air pollution, which are unfavorable to residents. Urban traditional blocks are facing the dual challenges of restoration and protection. This paper proposes adaptive transformation strategies for improving the microclimate of traditional areas. We selected Baxian’an Block in Xi’an city, simulated the air temperature and wind speed during summer and winter using ENVI-met, and studied the correlationship between morphological parameters (average building height, building density, enclosure degree, height fall, aspect ratio, and sky view factor) and air temperature and wind speed ratio. The case study revealed that the wind speed ratio of Baxian’an is relatively different in summer, reaching a maximum of 0.61, meaning that the ventilation capacity is significantly affected by the architectural form of the block. Finally, suggestions for the optimal design of the block’s form are provided: the building density should be less than 50%, the average building height should be more than 50 m, the enclosure degree should be less than 0.2, the height fall should be more than 41.7 m, and the sky view factor should be less than 0.5. This study can provide data and support for improving the planning and design standards of traditional residential areas.

“…In the surveyed works, we have found two common slice‐based approaches. In the first group, we have works that make use of static horizontal and vertical cross sections [SAYJ18, JN20, SAH20]. For example, Shaeri et al use vertical cross sections at different sections of a neighborhood and horizontal cross sections at different heights for the analysis of air speed and air pressure [SAYJ18].…”

Urbanization has amplified the importance of three‐dimensional structures in urban environments for a wide range of phenomena that are of significant interest to diverse stakeholders. With the growing availability of 3D urban data, numerous studies have focused on developing visual analysis techniques tailored to the unique characteristics of urban environments. However, incorporating the third dimension into visual analytics introduces additional challenges in designing effective visual tools to tackle urban data's diverse complexities. In this paper, we present a survey on visual analytics of 3D urban data. Our work characterizes published works along three main dimensions (why, what, and how), considering use cases, analysis tasks, data, visualizations, and interactions. We provide a fine‐grained categorization of published works from visualization journals and conferences, as well as from a myriad of urban domains, including urban planning, architecture, and engineering. By incorporating perspectives from both urban and visualization experts, we identify literature gaps, motivate visualization researchers to understand challenges and opportunities, and indicate future research directions.

“…For this aspect, researchers often use microclimate simulation software to conduct the research. By using CFD simulation, the architectural elements that could moderate outdoor thermal conditions were explored, and the role of open spaces and alleys were evaluated in a traditional urban district quantitatively (Shaeri et al 2018). By using ENVI-met software, the effectiveness of strategies, such as green roofs, cool roofs, cool pavements, green areas, and air passages, was veri ed for improving the thermal environment in a dense and old city district (Evola et…”

During the process of the high-speed urbanization in Chinese cities, traditional districts renewal is attracting more and more attention. Up to now, the social, economic, political status, and the interaction between each factor have been seriously discussed on urban traditional districts. However, the effects on urban microclimate and the residential living conditions in traditional districts are not well discussed. However, it is strongly related to the living comfort and citizens' well-being. In this research, two typical traditional districts in Xi'an are selected as case study. According to the original situation of building functions and the community characteristics, two renewal plans are proposed by adding vegetation in open spaces (V), and adding vegetation combined with building redevelopment (V&B), in order to balance the living convenience and thermal environment. Via ENVI-met simulation, the effects of the district renewal plans on thermal environment includes wind speed, air temperature, and mean radiant temperature are evaluated. This study provides method of environmental evaluation for traditional districts renewal, which contributes to sustainable urban planning in historical districts, and provides recommendations for related policy development.
