摘要

在尼日利亚所有六个地缘政治区域的60所公立[小学和中学]的180间教室的室内照明水平(照度)，使用Hagner数字亮度计在三种不同的天空条件下(“晴朗”，“部分晴朗”和“阴天”)进行了12次实验研究。分析的实证数据为:“办公桌上靠近窗户、暴露在阳光直射和/或较高照度的工作的平均室内照度(Ld(DSL))”范围为1,243 lux-4,486 lux，“办公桌上靠近窗户、暴露在间接阳光和/或较低照度的工作的平均室内照度(Ld(ISL))”范围为674 lux-2,987 lux，“教室中央课桌上作业的平均室内照度(Ld(CrC))”范围从101勒克斯到449勒克斯，“板子上作业的平均室内照度(Lb)”范围从110勒克斯到494勒克斯。三个全球推荐的标准[CIE-ISO, IESNA和EN]，教室活动的最小/最佳照明水平值，如“在黑板上阅读”(Lsb 500勒克斯)和“在桌子上书写，绘画和阅读”(Lsd = 300勒克斯);随后的统计分析显示，教室里“太阳照射过度”和/或“照明不足”。

An evaluation of classroom-illumination: a critical requirement for effective designing and construction of naturally-illuminated schools in Nigeria

Indoor lighting-levels (illuminances) of 180 classrooms in 60 public [primary and secondary] schools located in all six geopolitical zones of Nigeria, were experimentally investigated 12 times under three different sky-conditions ['clear', 'partly-clear' and 'overcast'] using the Hagner digital lux-meter. The analysed empirical-data were: 'Mean indoor illuminance for tasks on desks' tops near windows exposed to direct sunlight and/or higher illumination(Ld(DSL))' ranging from 1,243 lux-4,486 lux, 'Mean indoor illuminance for tasks on desks' tops near windows exposed to indirect sunlight and/or lower illumination(Ld(ISL))' ranging from 674 lux-2,987 lux, 'Mean indoor illuminance for tasks on desks' tops at Center of Classroom(Ld(CrC))' ranging from 101 lux-449 lux and 'Mean indoor illuminance for tasks on boards(Lb)' ranging from 110 lux-494 lux. Three globally recommended standards' ['CIE-ISO', 'IESNA', and 'EN'], values [of minimal/optimal lighting-levels for classroom-activities like 'reading on the blackboard' (Lsb 500 lux) and 'writing, drawing and reading on desks' (Lsd = 300 lux)]; and the follow-up statistical-analyses reveal 'excessive solar irradiation' and/or 'inadequate illumination' in the classrooms.
