Assessment of Interior general lighting in Hospitals based on standards of North America Illumination Engineering Society

Comfort lighting is one of the most important topics, which provides optimum Physical conditions in general environment and workplaces such as hospitals. The aim of this study was Assessment of Interior general Lighting in Hospitals based on standards of North America Illumination Engineering Society.
This Descriptive – analytical study was conducted in April 2015. Illumination of different parts of Imam Reza hospital in Ivan city was measured according to standards of North America Illumination Engineering Society. Lighting intensities were measured using a lux meter (TES-1332A Light Meter) in the early hours of day (10 Am). Finally, the data were analyzed using SPSS version 20.
The results of this study showed that 53.33 percent of general lighting intensities at different parts of hospital are unsuitable. The average of interior lighting intensities in the hospital was 140 ± 31.26 lx, which is lower than recommended standard. Maximum Lighting intensities recorded in the of corridor men ward and minimum Lighting intensities recorded in examination room. Statistical analysis showed a significant difference among the lighting intensities of different parts of the hospital (P=0.001).
The results of this study showed that general lighting intensities in the studied hospital is unsuitable and corrective action such as lighting systems redesign and modification of lightening systems for increasing general Lighting intensities is necessary.
