Additional Considerations:

• Energy Efficiency: The Saudi Code emphasizes the importance of energy-efficient lighting system designs, encouraging the use of LED lamps and smart control systems.

• Activity Type: The nature of tasks performed in the space dictates the required illumination level; highly precise tasks demand higher intensity.

• Lighting Quality: Beyond intensity, lighting quality includes uniformity, glare control, Color Rendering Index (CRI), and Correlated Color Temperature (CCT).

• Maintenance: A Maintenance Factor should be considered during design to ensure illumination levels remain within specified limits throughout the lifespan of the installations.
