基于风环境响应的可变建筑表皮设计策略研究

Design of Dynamic Building Facades Based on Wind Environment Response

与传统静态建筑表皮相比,可变建筑表皮因具有动态适应性能够更好地适应室外环境变化。而在现有的研究中,对基于风环境响应的可变建筑表皮的研究较少。通过案例研究,将基于风环境响应的可变建筑表皮分为可变通风表皮、风动幕墙两类。可变通风表皮可以对室外环境因素进行实时响应以降低建筑能耗并提高室内舒适度,在国家大力提倡“碳达峰、碳中和”的政策背景下,可以更好地满足低碳建筑要求。风动幕墙可以与风环境互动创造灵动的立面效果,提高立面视觉美学。分别从响应因子、运动方式的角度对两类表皮的设计策略进行梳理,为之后基于风环境响应的可变建筑表皮的设计及应用提供参考。

Compared with the traditional static building facade,dynamic building facade can better withstand the fluctuation of outdoor environment because of its dynamic adaptability.In the existing researches,there are few researches on dynamic building facades based on wind environment response.Through case study,dynamic building facades based on wind environment response can be divided into two types,including the dynamic ventilated facade and the pneumatic curtain wall.Dynamic ventilated facade can respond to outdoor environmental factors in real time to reduce building energy consumption and improve indoor comfort,which can better meet the requirements of low-carbon buildings under the background of the national policy of promoting peak carbon dioxide emissions and carbon neutrality.Pneumatic curtain wall can interact with the wind environment to create a flexible facade effect and improve the visual aesthetics of facade.The design of these facades is sorted out from the aspects of response factors and movement forms,which provides reference for the design and application of dynamic building facades based on wind environment.
