摘　　要：目前,公共建筑中庭物理环境舒适度不足,且建筑集成化物理性能模拟较缺失。基于中庭物理环境待优化的目的,通过Grasshopper建立集成参数化模拟平台,以光环境、热环境、风环境舒适性为评价维度,以全年热舒适小时数、采光系数、全天然自然采光百分比、眩光指数、室内平均风速为优化指标,对京津冀地区典型二、三、四向中庭的层高、中庭天窗比、窗墙比、窗台高度、走廊宽度等设计参数进行多目标优化模拟,并基于上述模拟最优解集运用Odeon对语言传输指数进行进一步筛选,分别获得优选设计参数指标,并获得以光热舒适性为目的的中庭设计参数建议。所提出的集成化模拟流程和可为建筑设计初期的中庭设计提供参考。Atrium space is the core part of public buildings,and its physical environment indicators have always been valued by people.Reasonable design has a good passive adjustment effect on the main body of the building,which is conducive to creating a comfortable and energy-saving internal environment,while unreasonable atrium design has a huge negative impact on the overall environment.In the primary stage of architectural design,architects’ decisions often have a decisive impact on the comfort of the physical environment of the building.By adding integrated perfor mance simulation in the early design stage,we can quickly obtain simulation performance feedback,draw the relations between architectural design and simulation performance,and improve design efficiency.Building physical environment indicators mainly include light environment,thermal environment,wind environment and acoustic environment.These environmental evaluation indicators can be quantified and have the preconditions for optimization.However,due to the complex relations between the various objective functions of building performance,multi-objective optimization has become a better method to solve this problem.However,the previous information interaction between architects and professional simulation engineers is inefficient,and the simulation of physical environment is limited to one aspect of light,heat and wind environment,and there is little comprehensive parametric research.Based on the purpose of the atrium physical environment to be optimized,this paper establishes an integrated parametric simulation platform through grasshopper,taking the comfort of light environment,thermal environment and wind environment as the evaluation dimension,and taking the annual thermal comfort hours,lighting coefficient,natural lighting percentage,glare index and indoor average wind speed as the optimization indicators,analyzes the floor height,atrium skylight ratio,window wall ratio,windowsill height,the corridor width and other design parameters are simulated for m
