In common office space, the recommended level of illumination is often lower than that of task areas, where visual accuracy and concentration are critical. The guidance that common areas should have one-third of the luminescence compared to task areas reflects the balance needed for effective functionality and comfort in various zones of an office. Task areas, like workstations or meeting rooms, typically require brighter lighting to facilitate activities such as reading, writing, and detailed work.

Having one-third the illumination in common areas ensures that there is sufficient ambient light for general navigation and comfort without causing glare or distraction during tasks that occur in more focused zones. This ratio helps promote energy efficiency by not over-illuminating spaces that do not need as much brightness while still providing enough light for basic activities. Therefore, the answer aligns well with best practices in lighting design for office environments, supporting both energy conservation and ergonomic considerations.
