本刊讯国家标准GB/T 18091-2015《玻璃幕墙光热性能》日前发布,自2016年8月1日起实施。该标准从光热平衡的角度,首次规定了幕墙玻璃光热比的分级要求,对于指导玻璃幕墙设计和选型提供了重要指导。同时,为了限制玻璃幕墙反射光对周边建筑和道路安全造成干扰和危害,标准首次提出了玻璃幕墙有害反射光的定量评价指标,为保证视觉健康和行车安全提供了科学依据。在编制组的技术支持
The Journal of National Standards GB / T 18091-2015 “glass curtain wall thermal performance” has been released since August 1, 2016 onwards. The standard from the light heat balance point of view, for the first time stipulated the curtain wall glass light heat ratio grading requirements, for guidance glass curtain wall design and selection provides an important guide. In the meantime, in order to limit the interference and harm caused by the reflected light from the glass curtain wall to the surrounding buildings and road safety, the standard first proposed the quantitative evaluation index of the harmful light reflection of the glass curtain wall and provided a scientific basis for ensuring visual health and driving safety.
