街区式商业综合体公共空间热环境和使用者行为耦合度评价方法和模式研究

作为评价公共空间的重要指标，热舒适性是客观热环境和使用者主观体验共同作用的结果。申请人的前期研究表明：对于集聚大量使用者的公共空间，热环境同使用者在空间分布中重叠和错位的关系（耦合度）是影响热舒适体验和使用者评价的重要因素。针对这一影响热舒适预测可靠性的关键问题的研究目前尚处空白。.研究将以街区式商业综合体外部空间这一高密度环境中热环境受到物质形态影响最为显著、容纳大量公共活动的典型公共空间类型为对象， 以热环境模拟方法的优化和基于元胞自动机的行为模拟关键技术的研发为基础，完善基于ArcGIS的热环境和行为数据栅格化和叠图整合方法，采取回归分析方法归纳能够准确表征总体热舒适性的耦合度指标值域，进而通过参数化建模归纳建筑群体类型的耦合模式分类图谱。.研究对于推动环境热舒适领域的研究具有前沿性和较强的理论价值，也为高密度环境公共空间的评价和优化，以及规划设计方案的评估和决策提供理论和技术支撑。

Thermal comfort, a key criterion in evaluating public space, results from objective thermal environment and users’ subjective experiences together. The applicant’s research has achieved some preliminary findings that essentially, the overlapping and deviation patterns coupled by thermal environment and spatial behavior can levy significant impact on the thermal experience and satisfaction in public space gathering large number of users. This key issue that may affect the reliability in thermal comfort prediction still remains a research gap. .The research will focus on a typical type of public space in this study – high-density commercial block. It is characterized by its thermal environment being dominated by the physical environment, and its public space holding massive public activities. Based on the optimized methodology of thermal environment modelling and the technology of behavior simulation by Cellular Automata, we will further refine the technology of rasterization and overlaying of thermal environment and spatial behavior data in ArcGIS. The index domain of coupling degree which can precisely present the overall thermal comfort will then be regressed. We will also attempt to summarize an atlas of coupling patterns categorised in typologies of building groups by parametric modelling. .The study will fill an unheeded gap of research in the field of environmental thermal comfort and facilitate the reliability thermal comfort prediction. It will also support the evaluation and optimization in public spaces in high-density built environment, and sustain the assessment and decision-making process for planning and design.
