Percentage of time subjects were found asleep under two lighting conditions (slides 14 and 15).

Average light/dark ratio before and after intervention (slide 16).

Photos of room with proposed 24 hour lighting solution (slide 17).

Summary (slide 18)

Light isn’t just for vision anymore

Light touches every aspect of our lives

Much of the information we gather from the environment is through the retina

Architects can incorporate scientific findings into their design now

Integration (circadian, visual, perceptual, aesthetic) is needed and qualitative solutions (e.g., daylight, high CCT, bright or dim light) aren’t good enough
