DAYLIGHT Symposium 2011
Daylight in a Human Perspective

The theme of the 4th VELUX Daylight Symposium “Daylight in a Human Perspective” focused specifically on the effects of daylight on building occupants; how are we affected by daylight and what are the requirements to achieve good daylit environments.

Today, we can estimate daylight contribution in any room with fairly high precision (vision), but we do not know, with the same precision, what kind of daylight contribution is associated with improved human health and well-being (circadian regulation). Preliminary evidence suggests that we receive too small a daily light dose and that low light exposure during the day is associated with diminished health and well-being, including reduced sleep quality, depressed mood and poorer social relations. These ill effects place a substantial burden on individuals and the economy.
