Lighting Determines Whether Employees Shine  – Studies Show that Under-lit Spaces Affect Employee and Student Productivity and Well-being
Studies over the past 20 years have covered lighting and workplace productivity. Much of the recent research continues to cite these studies as a basis of support
for improved productivity using LED lighting. The studies blame lack of productivity on things like flicker, lack of focused light, inability to control brightness, and mood inhibitors caused by unnatural color temperatures. All of these productivity killers can be corrected by Advanced Energy’s LED solutions.

The Studies and Specifics:
Study 1: “Effects of Four Workplace Lighting Technologies on Perception, Cognition, and Affective State” (2010)
Summery – “The present results indicate that recent increases in the number of LEDtechnologies being incorporated into industrial lighting applications
may be justified given the positive implications for worker performance. Relative to traditional fluorescent technology with relatively low color
temperature, LED appears to support positive mood, extended wakefulness, and speeded performance on both visual perceptual and cognitive tasks.”

Study 2: “Building Investment Decision Support for Six Energy Efficient Lighting Retrofits (2013)
Key Findings – LED light fixtures, occupancy sensors, daylight harvesting, task lights, blinds, and high performance fixtures with automation systems all
produce “triple bottom line” savings.

Vertically integrated LED light fixtures paired with dimming and IP control lead to:

– 8.34% improvement in work performance
– 33% improvement in mood ratings with LED
– 33% mood improvement translates to 5.76 work efficiency increase
– 3rd bottom line cumulative ROI equals 289%

Study 3: “Green Building and the Bottom Line” (1998)
Key Findings – Designs and actions that improve visual acuity and thermal comfort seem to result in these gains:

– 15% decreased absenteeism
– 25% decreased absenteeism
– 16% increase in claims processed
– 20% improvement in defect rate
– Improved product quality = $25,000/yr
