Summary
This study assessed a newly installed circadian lighting system in a neurology ward at Zealand University Hospital using CIE S026 standards and the Luox platform to calculate melanopic EDI and related metrics. The findings underscore that access to daylight is critical for both adequate illumination and circadian entrainment in hospital patients, and that the measurement framework combining spectrophotometry, Luox, and CIE S026 provides a reliable methodology for evaluating integrative lighting in clinical settings.
Key Findings
- Access to daylight was found to be essential for both sufficient illumination levels and circadian entrainment in hospital ward patient rooms.
- Lighting conditions were evaluated under both minimal and abundant daylight access scenarios, demonstrating significant differences in MEDI and circadian performance metrics.
- The combined use of the Luox platform, CIE S026 standard metrics (illuminance, CCT, MEDI, MLIT), and melatonin suppression models was validated as suitable for accurate assessment of integrative hospital lighting.
