基于光热环境优化的动态建筑表皮单元运动方式研究——以旋转表皮为例

Motion Mode of Dynamic Building Skin Unit Based on Photothermal Environment Optimization:Taking Rotating Skin as an Example

近年来动态表皮已被广泛应用到建筑设计中,除了优越的美学效果,其对室内光热环境的调节作用也逐渐被设计师重视。以济南地区某典型办公空间为研究对象,基于Ecotect和Daysim模拟软件建立分析模型,比较分析了动态表皮的3种基本运动方式和6种叠加运动方式对室内光热环境的影响,研究结果表明:3种基本运动方式中,沿水平轴旋转的表皮对室内光热环境的优化效果最好,沿对角线运动方式次之;相较于基本运动方式,6种叠加运动方式的表皮普遍对室内光热环境的优化效果有所提升,其中,沿对角线旋转叠加水平轴旋转的表皮对室内光热环境的优化效果最好。为基于建筑物理环境性能优化的动态建筑表皮设计提供参考。

Dynamic skin has been widely used in architectural design in recent years.In addition to its superior aesthetic effect,its regulation of indoor light and heat environment has gradually been paid attention to by designers.Based on Ecotect and Daysim simulation software,the typical office space in Jinan is researched,an analysis model is established,the effects of three basic motion modes and six superimposed motion modes of dynamic skin on an indoor photothermal environment are compared and analyzed.The results show that the skin rotating along the horizontal axis has the best effect on the photothermal environment,followed by the skin moving along the diagonal;The epidermis cases of six superimposed motion modes generally improve the adjustment effect of indoor photothermal environment compared with the basic motion mode.Among them,diagonal rotation superimposed on horizontal axis rotation has the best adjustment effect on indoor light and thermal environment.It provides a reference for dynamic building skin design based on optimization of building physical environment performance.
