Daylight-controlled Lighting Adjusted for Geographical Orientation : Effects on Recovery, Energy Consumption and User Satisfaction
Sponsor: Mental Health Centre Copenhagen, Bispebjerg and Frederiksberg Hospital
Summary
The trial takes place in 4 psychiatric closed wards at Ny Psykiatri Bispebjerg. The objective is to compare, retrospectively, over two consecutive winter periods (2022 and 2023) the effect of the lighting on the duration of stay of the patients. During the first winter, a standard lighting is used, and, during the second winter, the lighting will be modified to favor a greater light intensity in blue wave color light in the morning and a gradual decrease in light intensity in the evening adjusted for geographical orientation of the patients' rooms.
