Study on the Effect of the Layout of Daytime Activity Space on the Annual Vertical Daylight Exposure on the Eye in Elderly Facilities
Abstract
Lighting has been identified as a significant environmental attribute responsible for promoting physical and mental health of the elderly. However, present guide and standard focuses mostly on horizontal illumination requirements for specific tasks, but less on vertical lighting. This study attempts to evaluate lighting quality of the daytime activity space in Beijing’s elderly facilities from the configuration of vertical daylighting on the eye by DAYSIM simulation based on dynamic climate, and to analyze the influence of position orientation on vertical daylight exposure on the eye so as to explore the possibility and design technology to optimize the non-visual based lighting quality.
