The personalisation of lighting, to meet individual needs, is essential for human performance and well-being. According to the Commission Internationale de l’Éclairage (CIE), adaptive lighting responds to environmental conditions and individual requirements. In this study, adaptive lighting refers to the integration of natural light, diffuse electric lighting, and task lighting, automatically adjusting to optimise visual comfort and energy efficiency. Based on simulations of eight scenarios, the results demonstrated that adaptive lighting enhances visual comfort and ensures adequate illuminance levels under varying conditions. The integration of these sources significantly reduced energy consumption, with scenario 06 LD + LE (105 kWh/month) standing out in comparison to scenario 04 LE (369 kWh/month). However, the absence of appropriate luminous hierarchy generated excessive contrast, which may lead to eye strain. The study reinforces the relevance of adaptive lighting and suggests further validation in real-world environments.
