Inadequate lighting levels in a CO2 gas unit led to measurable deficiencies in illuminance across different work shifts, necessitating a redesign of artificial lighting to meet recommended standards and improve operational outcomes. This human factors research insight is drawn from a 2015 study published in Jundishapur Journal of Health Sciences. Using Descriptive-analytical survey and quantitative analysis, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must proactively assess and address environmental factors like illumination as integral components of workplace design, rather than afterthoughts, to optimize human performance and safety.
Suboptimal workplace illumination significantly impacts worker performance and safety.

Key Findings
- 01Average illuminance levels varied significantly across shifts: morning (211.31 ± 292.07 lx), evening (182.16 ± 205.16 lx), and night (67.47 ± 71.10 lx).
- 02All measured average illuminance levels were below the recommended standard of 300 lx.
- 03A significant difference (P < 0.001) was found between measured and standard illuminance values across the shifts.
Application
Design takeaway
Designers must proactively assess and address environmental factors like illumination as integral components of workplace design, rather than afterthoughts, to optimize human performance and safety.
How to apply
Before finalizing any workplace design, conduct a thorough assessment of existing lighting conditions and use established methods like the lumen method to design an appropriate artificial lighting system that meets ergonomic standards.
Project actions
- 01When assessing a workplace, remember to measure all relevant environmental factors, not just the obvious ones.
- 02Use quantitative data to support your design decisions and demonstrate the impact of your proposed solutions.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Quantitative measurement of illuminance levels.
- +Comparison against established standards.
- +Design proposal based on a recognized method (lumen method).
Limitations
The specific type of CO2 gas and its properties might influence the required lighting spectrum or intensity, which was not explored. The study also did not account for individual worker visual acuity.
Reliability & validity
Reliability could be improved by taking multiple readings at each measurement point and averaging them. Validity is supported by comparing findings to established illuminance standards.
Think critically
How might the specific chemical environment of a CO2 gas unit (e.g., potential for glare or reflections, need for specific light spectra for safety checks) influence the optimal lighting design beyond just lux levels?
Design Principles
"Workplace illumination levels should be quantitatively assessed and designed to meet or exceed established ergonomic standards to support optimal human performance and minimize errors."
This research highlights the critical role of environmental factors, specifically illumination, in influencing human performance within industrial settings. Designers and engineers must consider lighting not just for visibility, but as a key element impacting cognitive function, error rates, and overall safety.
What This Means for Your Design
Bad lighting at work makes people tired and more likely to make mistakes. This study measured the light in a factory and found it was too dim, so they figured out how much new light was needed to make it better.
