公共建筑中庭天然采光眩光模拟研究——以四向中庭为例

Study on the Glare Simulation of Natural Lighting in the Atrium of Public Buildings——Taking the Four-way Atrium as an Example

前期调研发现公共建筑中庭空间天窗采光的眩光问题较为严重,针对此类无固定视线方向的中庭空间,本文提出基于空间视场的眩光视觉不舒适概率为眩光的评价指标(SFVD),建立Rhino为基础的Grasshopper参数化平台,针对四向中庭空间,对天窗的开窗面积和分布进行眩光模拟分析,获得公共建筑中庭天窗降低眩光影响的措施建议。

Preliminary investigations found that the glare problem of skylights in the atrium space of public buildings is serious.For such atrium spaces without a fixed line of sight,this paper proposes the glare evaluation index(SFVD)based on the glare visual discomfort probability of the spatial field of view,and then establishes the Grasshopper parametric platform based on the Rhino.The opening area and distribution of the skylights are simulated and analyzed for the four-way atrium space,and suggestions are obtained for measures to reduce the impact of glare on the skylights of public buildings.
