Energy Efficiency & Smart Lighting
Enhancing Building Energy Efficiency with a Modular AI-based Smart Lighting System
This study proposes a modular, AI-based smart lighting system to enhance building energy efficiency, particularly for retrofits. Unlike conventional closed-loop systems, it uses a distributed architecture with a Master LED Luminaire (MLL) coordinating Slave LED Luminaires (SLLs). The MLL incorporates an SVR-based daylight prediction model to estimate indoor daylight availability using fixed architectural parameters and real-time outdoor irradiance. The system was validated in a public building and showed clear advantages in scalability, ease of installation, and reduced infrastructure costs compared to traditional on-off and sensor-based closed-loop controls, despite a slightly higher artificial lighting demand than closed-loop. Its IoT-enabled communication allows real-time parameter updates and adaptive dimming. This approach offers a cost-effective retrofit solution, addressing installation, maintenance, and adaptability challenges of conventional lighting control systems.

Real-World Deployment Success
The system was implemented and validated in a public building, an office measuring 600 × 700 cm (42 m²) with two windows totaling 2.38 m² of glazing. Comparative evaluation against traditional on-off and sensor-based closed-loop controls demonstrated clear advantages in scalability, ease of installation, and reduced infrastructure costs. It maintained target illuminance with a daily artificial lighting demand of 66.4% compared to the on-off baseline.
Future Enhancements: Hybrid Feedback-Prediction
Future research will explore hybrid feedback-prediction strategies, integrating selective low-cost sensors in high-variability zones to further close the performance gap with closed-loop systems, while maintaining the economic advantages of the open-loop approach. This includes advanced AI models like deep learning with temporal attention or hybrid models combining weather forecasts and real-time sensor inputs to enhance prediction accuracy and potentially reduce energy consumption.
