Application of Different Circadian Lighting Metrics in a Health Residence

During the last three decades, various scientific researchers analysed the connection between natural elements and human life, both as far as well-being and productivity. This study simulates circadian lighting metrics on elderly occupants in a healthcare residence, with different types of metrics. It presents an application of some metrics that try to quantify the effects of natural light on the human being. Circadian Action Factor, Circadian Stimulus, and Equivalent Melanopic Lux are considered. Starting from the spectral power distribution parameter, the three metrics are compared. The final aim is to build up a standard technique to represent the effect of key design choices on the accomplishment of endorsed circadian framework boost for healthcare residences occupied by elderly people.
