摘要
照度均匀度是关系到体育场馆自然采光、运动员比赛和电视转播的重要建筑光学指标,现有研究多采用软件模拟方式,且多未全面考虑CIE 15种天空模式。针对中型体育场比赛厅,提出一种基于人工天穹和CIE 15种天空模型的照度均匀度实验方法。按照国内体育场馆设计标准,1∶10搭建建筑模型,给出其尺寸和高度选择依据;全面考虑顶界面采光、侧界面采光和顶、侧界面三种自然采光模式;选择5 mm磨砂玻璃作为采光材料,真实测量其透射比及内墙面材料的反射系数。在此基础上,基于哈尔滨工业大学寒地建筑研究院的人工天穹进行CIE 15种天空模型下的照度均匀度实验,其数据分析为体育场馆的工程设计提供重要理论借鉴价值。
Illumination uniformity is an important building optical index related to natural lighting of stadiums,athletes’competitions and TV broadcasting.Current studies mostly use software simulation methods,and mostly do not consider CIE 15 sky patterns.An experimental method of illumination uniformity based on artificial sky vault and CEI 15 sky models is proposed for medium-sized stadium.According to the domestic design standards of stadiums,a building model is built at 1∶10 to provide the basis for the selection of its size and height;three natural lighting modes,i.e.top-interface lighting,side-interface lighting and top-side-interface lighting are considered comprehensively;5 mm trostecl ground glass is selected as lighting material to measure its transmittance and reflection coefficient of inner wall materials.On above basis,based on the artificial sky vault of the Cold Region Architecture Research Institute of Harbin Institute of Technology,the experiment of illumination uniformity under CIE 15 sky models is carried out.The data analysis provides important theoretical reference value for the engineering design of stadiums.
