Abstract (Synopsis):

The criteria for lighting design that optimizes task performance, provides visual comfort and saves energy has been well established.  But there are three known routes through which lighting affects people: visual, perceptual and circadian. How and what we see can have a direct impact on our physical and psychological experience. There is a growing body of research that supports the existence of non-visual effects of light that can serve different biological functions including cognition, well-being and sleep. Today’s lighting systems, especially with LEDs, are providing enhanced capabilities to implement designs that not only meet our visual needs but improve our biological responses to our environment. Of particular interest is the role of the circadian system as it impacts performance, well-being, satisfaction and comfort.


Learning Objectives:

  1. Understand the mechanisms of the human visual system and the circadian system.
  2. Understand the implications of aging on the visual system.
  3. Evaluate research findings on the impact of spectral distribution, timing, intensity and duration on the circadian system.
  4. Understand the implications for lighting design, with a focus on institutional applications.
  5. Evaluate electric lighting and daylighting solutions that can positively impact visual performance and circadian responses.
