基于Dynamic Daylighting软件的采光系数与实测采光系数的比较研究——以某学院多媒体教室为例

A Comparative Analysis of Daylight Factor Based on Dynamic Daylighting Software and Measured Daylight Factor:Taking a College Multimedia Classroom as an Example

为了评价浙江同济科技职业学院多媒体教室的天然采光设计是否能够满足《建筑采光设计标准》中关于采光系数的要求,选取教学楼B311,B314,B319多媒体教室为对象,对实测计算的静态采光系数与应用Dynamic Daylighting软件模拟的动态采光系数进行比较分析。结果表明:教学楼B311,B314,B319多媒体教室的采光情况能够满足标准的要求;根据不同的天空亮度分布,Dynamic Daylighting软件可以对简单矩形房间内的实时动态采光系数进行模拟,与实测计算的静态采光系数相比,两者在结果和对各个参数的响应方面都较为一致。这为Dynamic Daylighting软件广泛应用于建筑光环境的模拟分析提供了一定依据。

In order to evaluate whether the natural lighting design in multimedia classrooms in Zhejiang Tongji Vocational College of Science and Technology can meet the requirements of the daylight factor in Standard for Daylighting Design of Buildings,the multimedia classrooms of B311, B314 and B319 in the teaching building were selected as the objects, and the measured and calculated static daylight factors were compared with the dynamic daylight factors simulated by Dynamic Daylighting software.The results show that the lighting conditions of B311, B314 and B319 multimedia classrooms can meet the requirements of the standards. According to different luminance distribution of the sky, Dynamic Daylighting software can simulate the real-time dynamic daylight factor in a simple rectangular room. Compared with the measured static daylight factor, the results and the response to each parameter are consistent. It provides a basis for Dynamic Daylighting software to be widely used in the simulation analysis of building light environment.
