Some basic lighting facts for Building Professionals

• Improving employee productivity - Improving productivity is an essential part of quality improvement. In fact, research shows when lighting quality rises, process costs fall because better visual conditions enable people to work faster with fewer errors. The fact is higher quality lighting enhances the effectiveness of visual reviews and inspection, thereby increasing productivity.
  
  
• Higher quality lighting - Higher lighting quality means comfort, good color, uniformity and balanced brightness, all factors which contribute to long-term employee work performance. Shadows, glare, flicker or chaotic patters of light or fixtures are distracting to employees and should be avoided.
  
  
• Illumination - Selecting quality lighting for employee work areas depends on the type of task performed in that area. For example, an employee working at a desk with a computer must be able to read information on the computer screen and printed/written materials. If an area is used for several types of tasks, then the overall visual environment should be considered, which includes evaluating visual comfort, shadows and visual aesthetics.
