Harnessing The Power of Healthy Rhythmic Daylight: A Simulation-based Approach in Healthcare Environments

Abstract

This research aims to examine and evaluate the presence and quality of rhythmic daylight in healthcare facilities, particularly in patients' rooms. The study evaluates whether the natural lighting design within these rooms simulates and mimics rhythmic patterns found in natural daylight. Using computer simulation tools, such as VELUX Daylight Visualizer and Rhino with ALFA, this research evaluates key daylight performance metrics, including daylight illuminance, color temperature, daylight factor, daylight availability, and the melanopic/photopic ratio in selected patient rooms at King Abdullah University Hospital (KAUH) in Irbid City. Results indicate that current daylight conditions fail to provide adequate exposure to rhythmic daylight cycles, potentially disrupting patients’ circadian regulation. This study emphasizes the need for evidence-based daylighting strategies that integrate circadian-supportive design principles into healthcare architecture. These strategies aim to create environments that promote better health outcomes and well-being in healthcare settings.
