A lighting evaluation of a facility for the elderly.

A residential facility for the aged was evaluated for their illumination needs. Only the shared facility and grounds immediately surrounding it were considered. The facility evaluated is one of the most modern and the lighting design is considered its best feature. The age of residents occupying the facility ranges from 60 to 85 years. The lighting evaluation included administering a lighting adequacy/inadequacy questionnaire and measurement of actual light levels in the various parts of the facility during the day and after dark hours. The results indicated that lighting in approximately half the areas surveyed was substandard. An attempt to develop recommendations for the lighting needs of the elderly was unsuccessful. It was concluded that realistic illumination level recommendations need to be developed for the elderly.
