Summary
This study investigates the use of biodynamic (dynamic, circadian-supportive) lighting in three senior care facilities, measuring melanopic light levels alongside other indoor environmental quality factors such as thermal comfort, air quality, and acoustics. The findings suggest that optimizing these IEQ components together — including lighting — can meaningfully improve living conditions for elderly residents who spend most of their time indoors.
Key Findings
- Optimal ranges for each IEQ component (lighting, air quality, thermal comfort, acoustics) were achieved, with average values reaching 72% of ideal benchmarks after the optimization algorithm converged.
- Strong correlations were found between IEQ components, suggesting that improving one factor (e.g., lighting) can positively influence others in elderly care environments.
- A Self-Adaptive Ensemble Differential Evolution Algorithm was proposed and validated for multi-objective IEQ optimization in institutional care settings.
