上海市黄浦区中小学教室光环境现状研究

Survey on Light Environment in Primary and Secondary School Classrooms in Huangpu District of Shanghai

目的了解上海市黄浦区中小学教室光环境现状,为改善中小学校教室光环境提供理论依据。方法2021年5月选取辖区内64所中小学校,对384所教室进行光环境调查,按照中、小学教室进行比较。结果中小学教室的黑板面平均照度合格率为24.5%,采光系数合格率为41.1%,后/侧墙反射系数合格率为45.1%,课桌面照度均匀度合格率为46.9%,窗地比合格率为48.2%。中学教室窗地比、黑板面平均照度合格率明显高于小学教室,而小学教室的黑板反射系数、采光系数、后/侧墙反射系数明显高于中学教室。结论上海市黄浦区中小学教室光环境现状不佳,存在着较严重的问题,个别指标有待提高,教室光环境有待改善。

Objective To understand the light environments in primary and secondary schools in Huangpu District of Shanghai and to provide basis for school light environments improvement.Methods A total of 64 primary and secondary schools were selected in 2021.5.Light environments survey was conducted in 384 classrooms.Results were compared between primary and secondary schools.Results In primary and secondary school classrooms,the pass rate of average blackboard illumination is 24.5%,light-catching coefficient is 41.1%,rear/side wall reflection coefficient is 45.1%,uniformity of the desktop illumination is 46.9%,and ratio of window to floor is 48.2%.Pass rate of ratio of window to floor and average blackboard illumination in secondary school classrooms are significantly higher than that of primary school classrooms.Pass rate of blackboard reflection coefficient,light-catching coefficient,rear/side wall reflection coefficient in primary school classrooms are significantly higher than that of secondary school classrooms.Conclusion The current light environments in primary and secondary schools in Huangpu District of Shanghai are not very good.Problems are serious.Light environments need further improvement.
