Abstract

This research investigates the critical role of lighting design in hospitals environments, focusing on its impact on patient outcomes and environmental sustainability. By integrating energy-efficient LEDs and natural light, the study aims to enhance patient well-being and staff performance. To achieve this, the research explores aligning artificial lighting with circadian rhythms to improve both patient outcomes and staff performance. Using mixed-methods approach, the research includes a literature review, case studies, and analysis using DIALux simulation software. The literature review achieves a framework for sustainable, human-centric lighting, while case studies provide practical insights into effective designs in patient rooms. DIALux simulations assess lighting for energy efficiency, comfort, and visual quality. Findings reveal a significant 60% improvement in lighting quality at the One-Day Surgery Hospital case study, highlighting the benefits of adopting advanced lighting technologies. This study offers guidelines for optimizing hospital lighting, promoting patient well-being and environmental stewardship. Future research could explore quantifiable measures of patient recovery and staff performance to further validate the impact of lighting design in healthcare settings.
