Evaluating Lighting Condition of Primary Schools in 2015 (Case Study:Nahavand City of Hamadan Province, Iran)

The quality of vision is essential that universally understood about the human condition in a learning environment. In this regard, lighting exceeds than standard level increased visual fatigue as reflection decrease by eye blinks. Against exposure to lower maximum allowed to involve Nystagmus, headaches and impaired vision as the most significant symptoms for students. Therefore, this study aimed to evaluate the total lighting condition (a combination of natural and artificial lighting) in primary schools in Nahavand city and compared it with the international standards. This study investigated average lighting using illumination meter DX200 INS in Nahavand’s primary schools. Results showed that mean lighting for whole classrooms was 415.7±166 lux. Also, ratio of window area/floor area (WA/FA) was less than the standard ratio only in 8 classes from 121 totals with the coefficient of correlation 0.56 between illuminances average and ratio of WA/FA. These findings might have practical implications for the implementation of desirable and standard lighting in schools for better practice of students.
