Abstract: This paper presents a methodological framework and workflow for the simulation of the visual and non-visual lighting performance of a nursing home. A recentlydeveloped software tool, ALFA (Adaptive Lighting for Alertness), was used to estimate the adequacy of the lighting strategy to provide proper luminous conditions and circadian stimulation to the residents. Where required thresholds could not be met, improvement strategies were proposed and tested. This study provides evidence that robust methodologies and tools can support the design of spaces to comprehensively respond to the needs of visual comfort, task performance, and luminous satisfaction, while enhancing the circadian well-being of occupants.
