Measuring Circadian Light in Buildings: Findings and Actions

Lighting design for office buildings has focused largely on providing sufficient illumination for visual performance, minimal glare, good color rendering and energy efficiency. Little attention has been given to understanding how light affects the non-visual systems, including circadian regulation that affects sleep and mood. This course will discuss basic information about the importance of light and dark for entertaining circadian rhythms will be discussed. Findings from the field evaluation will also be presented with some “lessons learned” on how to maximize daylight and electric lighting in a space to increase circadian stimulation.
