隔热天穹——采光顶遮阳构造设计

Insulation Skydome Design of Sunlighting Roof Shading of BDIA

大型采光顶的遮阳问题,是采光顶在建筑中大面积使用的主要限制因素之一。大兴国际机场最终有魄力的选择了大面积采光顶造型方案。建筑团队为应对其带来的建筑能耗增加、旅客体感温度过热、室内对蓝天白云的可视化需求,进行了一系列金属与玻璃构造层次,金属百叶遮阳效率的设计实验。本文从设计遇到的难点问题出发,从原理入手,记录了设计、验证、实施一直到建成使用效果的全过程。

The shading problem of large-scale daylighting roofs is one of the main limiting factors for the large-area use of daylighting roofs in buildings.BDIA finally chose the large-area lighting roof shape scheme boldly.In order to cope with the increased energy consumption of the building,the overheating of the passenger’s body temperature,and the indoor visualization needs of blue sky and white clouds,the construction team conducted a series of metal and glass structural levels,and design experiments on the efficiency of metal shutters.This article starts from the difficult problems encountered in the design,starts from the principle,and records the whole process from design,verification,implementation to completion and use effect.
