Assessment of Lighting in Independent Living Facilities and Residents' Perceptions

People above the age of 60 need three times more light than a 20-year-old to perform the same tasks. Providing high light levels with limited amount of glare in eldercare environments enables the residents to function and negotiate their living space with confidence. This study acquired quantitative measurements of light levels in two independent living facilities (ILF) as well as measured the perceptions of the residents regarding their visual environment in these facilities. The results indicate that the quantitative light levels in the ILF were low and inadequate for proper function by the residents in the space when compared to the suggested recommended lighting practice for senior living (Illuminating Engineering Society of North America, 2007). However, the residents rated the lighting as average to good or comfortable. The study raises several questions about the positive responses of the seniors as well as provides tips to facilities management on improving the interior lighting quality of their facilities.
