Background & Objectives: Desirable and ergonomic lighting in the workplaces has a significant impact on the visual effects and improve the efficiency and productivity of employees. This study aims to evaluate the lighting system and feasibility of improving the artificial lighting system for comfort lighting in the workshop of the Fourth South Pars Gas Refinery.

Methods: In this descriptive-analytical study, the environmental conditions of the studied workshop were evaluated and the illuminance was measured in both day and night times at 216 points. Based on lighting measurements, a site map was provided. Further, based on current conditions of the workshop, illuminance was estimated using DIALux 4.12 lighting calculations software. In regard to the national recommended limits for industrial lighting and the current luminaires, the different practical, accessible and low cost solutions were presented. Using the mentioned software, the share of each proposed solutions for improving workshop lighting were estimated.

Results: The results showed that illuminance of the workshop in day and night times were equal to 197±71.5lx and 160±50.6 lx, respectively. The same results were also acquired by software calculations. Based on the results, lighting system was considered as undesirable lighting system along with need to modifications. Workshop lighting can increase between 260 lx to 405 lx through employing the proposed solutions based on the software predictions.

Conclusion: The results confirmed that the low cost and simple solutions can significantly be improved the ergonomic and comfort lighting in the workplace. The use of the specialized tools calculations by experts and designers can be also facilitated the conducting feasibility reliable.
