天然采光模型在探索性实验中的应用与分析

Application and Analysis of Daylighting Mode in Exploratory Experiment

为了提高学生对节能降耗的认识,掌握采光口的形状、位置与采光系数、采光均匀性之间的规律,共确定36种教室模拟模型,学生自己选择实验内容和实验模型,设计出一套科学的探索性实验方案。通过实验数据对不同采光口与采光系数、采光均匀度之间进行分析比较,得到如下3个结论:从节能方面考虑,建议教室的窗墙比大于1:3.5;从室内照明均匀度方面考虑,建议教室的窗墙比小于1:3.5;从综合性因数方面考虑,教室的窗墙比为1:3.5为最佳状态。

36 classroom raodels are identified in order to improve students ＇ awareness of energy saving and master the rules between the shape and position and coefficient of lighting and lighting uniformity. Students choose their own experimental content and models, design a set of scientific and exploratory experiment. Through the experimental data, different daylight position, daylight factor and lighting uniformity co- efficient were analyzed and compared, three conclusions were obtained as follows： window-to-wall ratio of the classroom shall be greater than l：3.S from aspect of energy efficiency; window-to-wall ratio of the classroom shall be less than 1：3.5 considering uniform from indoor illumi- nation; window-to-wall ratio of the classroom is i：3.S for the best considering the comprehensive factor.
