摘　　要：建筑表皮是多物理环境交互的接口,当前的建筑性能模拟软件多为针对单一环境的模拟,多环境联合模拟的工具平台较少。基于建筑运动几何学,遴选动态表皮的可控运动形式,提取24类动态表皮设计原型,建立面向控制的建筑表皮综合环境数字孪生模型,并结合案例对数字孪生模型及模拟平台进行应用验证。使用Python语言将模型封装成动态表皮综合环境模拟平台,针对不同表皮设计形式和环境场景模拟,可以快速直观地分析动态表皮的环境响应关系和性能。模拟平台融合了热环境、光环境、声环境和空气品质这四个综合环境,解决了建筑性能模拟软件无法多环境联合模拟的问题,从而满足对建筑表皮的仿真、预测、优化和控制等实际应用需求。The building facade is located at the interface between indoor and outdoor environments and is subjected to a range of variable environmental conditions.Based on variability of facades,dynamic building facades can make real-time responses to changes in the indoor and outdoor environments and user needs.Building facades can significantly decrease energy consumption for lighting and air conditioning and make positive contributions to indoor air quality,acoustic,visual and thermal comfort.Digital twins are a key to achieving the optimal indoor environmental control.However,research on the application of digital twins to dynamic building facades is still in its infancy.Building performance simulation software is one of the most common applications of digital modeling in architecture.Designers and researchers commonly use the building performance simulation software to simulate the performance of daylighting and ventilation systems.As the interface for interaction of multiple physical environments,building facade mainly includes thermal environment,light environment,acoustic and air environment.Existing building performance simulation software mainly focuses on single environment.There are still insufficient tools and platforms for multi-environmental combined simulation.In this study,three controllable movement modes(window opening,shading height and louver angle)of dynamic building fa?ade were selected and control able variables of building fa?ade movement were determined according to four environmental factors(indoor temperature,indoor illuminance,noises and CO2 concentration).A total of 24 types of dynamic fa?ade design prototypes were extracted and fa?ade geometric structures were recognized.Combining with physics,geometry and structural related knowledge of dynamic building facades,characteristic parameters of dynamic fa?ade under different design forms were extracted.The coupling relations between three fa?ade controllable movement forms and four environmental states were established.Digital twin models orienti
