基于图形参数化的夏热冬冷地区高层建筑群风环境评价与布局设计策略研究

In the current rapid urbanization process, the neglect of the impact of high-rise buildings on the outdoor wind environment has led to the formation of an unhealthy wind environment in some urban public spaces: poor ventilation affects the transfer of air pollutants and control of public outbreaks; excessive wind speed affects outdoor crowd activities and directly reduce the efficiency of public space.Even in extreme weather it will occur on the safety of personnel and items. The main content of this study is to clarify the impact of the spatial layout of high-rise buildings on the outdoor wind environment and to seek the evaluation tools that integrate the prediction of environmental physical indicators with the design of the spatial layout of buildings. By summarizing design parameter tables of high-rise building spatial layout based on wind environment assessment, mathematic models of wind environment and high-rise building spatial layout parameters are established by matlab language for mathematical analysis, and the functional relationship between wind environment indexes and layout parameters is proposed. Then , Using parametric design platform, the introduction of genetic algorithm, the function of the previous stage as a fitness function, the layout parameters as a genome, evolved from generation to generation, under the wind environment assessment of high-rise buildings group layout design strategy. The results have some theoretical innovation and practical operability, can serve the architectural design, urban design stage of the program, with obvious social benefits and invisible economic benefits.

当前快速城市化进程中忽视高层建筑群体对室外风环境的影响，导致一些城市公共空间中不良风环境的形成：通风不畅影响空气污染物的转移和公共疫情控制；风速过大影响室外人群活动，直接降低公共空间效能，在极端天气下甚至危害人员物品安全。本研究主要为明确高层建筑空间布局对室外风环境的影响机制，寻求环境物理指标预测与建筑空间布局过程相融合的评价工具，并提出相应的设计策略。通过归纳基于风环境评价的高层建筑空间布局的设计参数表，用Matlab语言建立风环境与高层建筑空间布局参数的数学模型进行数理分析，提出风环境指标与布局参数的函数关系；利用参数化设计平台，引进遗传算法思想、逐代演化，并试验修正，得到风环境评价下高层建筑群体布局设计策略。成果具有一定的理论创新性与实践操作性，能服务于建筑设计、城市设计的方案优化，具有显性的社会效益与隐形经济效益。
