Introduction: Illumination standards especially Illumination Engineering Society of North America (IESNA) and Iran lighting standards (ILS) are just based quantitative measurements. However, lighting has psychological effects and can influence quality and quantity of productivity and comfort of workers. Therefore, Illumination standards were undergone some changes. EN 12464-1 standards focus on the quality and quantity of lighting as well as the energy consumption. The aim of this study was to evaluate quality and quantity of lighting in Shemiranat health center.


Material and Method: In this study, first work tables were divided into 20×20 squares and illuminance was measured by putting HANGER S3 luxmeter sensor on the center of each square. In next stage, the luminance of each lighting source was measured from the view of observe and the average luminance of work table surface was calculated in the divide square. Furthermore, vertical, horizontal and lateral distance between observes eye and lighting source was measured. The gathered information was put in the equation and glare rate was calculated. Finally, according to the table we obtained color rendering index of lighting sources.


Result: Results of this study showed that maintained illuminance dose not mach the standards (500 lux) in any of the work station. Moreover, the glare match the standards just in less than 10 percent of the work area. Therefore, it is essential to reform the artificial lighting system and keep the maintained luminance and glare at the standard level.


Conclusion: There is a dramatic difference between the current lighting condition and the standard values. Therefore, making changes in lighting system is obviously essential.
