建筑玻璃幕墙光反射影响分析

ANALYSIS OF LIGHT REFLECTION EFFECT OF GLASS CURTAIN WALLS OF BUILDINGS

玻璃幕墙作为现代公共建筑外围护结构的常用形式,为建筑实现不同立面效果提供了更多的创作选择,但大面积、高反射的玻璃幕墙在建筑中的应用也对周边环境造成了光污染。以厦门市某幕墙建筑为例,通过现场调研确定受影响对象后,采用Ecotect软件进行光反射影响模拟,根据GB/T 18091—2015《玻璃幕墙光热性能》的相关要求进行评价分析,并提出该方法在幕墙光反射影响分析中的作用及不足,为相关设计单位进行建筑玻璃幕墙光反射影响评价分析提供参考。

As a common form of the outer envelopes of modern public buildings,glass curtain walls provide more creative options for building facades.However,the application of large-sized high-reflection glass curtain walls in buildings causes light pollution in the surrounding environment.Taking one curtain wall building in Xiamen as an example,the affected objects were determined by field investigation,the impact of light reflection was simulated with the Ecotect software,and evaluated and analyzed according to relevant requirements of GB/T 18091-2015“Optical and Thermal Performance of Glass Curtain Wall”.In addition,the role and shortcomings of this method in analysis of the effects of light reflection of curtain walls were proposed,as a reference for related design units to evaluate and analyze the impact of light reflection of architectural glass curtain walls.
