An energy efficient approach to minimize energy consumption for exterior lighting in Egypt

Lighting systems are crucial in enhancing architectural aesthetics while promoting energy efficiency in both building facades and outdoor areas, particularly in regions with high energy demands like Egypt. This research examines the applicability of different lighting solutions like LED lighting systems, intelligent “IoT-based” lighting systems, and solar-integrated lighting in the Egyptian context. The study compares each system’s performance, cost-effectiveness, and compatibility with architectural needs. LED lighting, with its high energy efficiency and adaptability to various architectural designs, emerges as a practical choice due to its low energy consumption comparable to other building loads, especially when integrated with intelligent lighting control systems, which utilize IoT and sensor-based controls, aligning with Egypt’s smart city initiatives and offering significant energy savings by adapting to real-time environmental conditions. Solar-integrated lighting, though promising as a renewable solution, faces challenges in dense urban settings due to spatial constraints and higher initial costs. The analysis concludes that Solar powered LED and intelligent lighting systems are the most applicable technologies for lighting in Egypt, supporting sustainability and urban development goals. Future research can work on the application framework and guidelines that can be used as a reference for efficient lighting design in Egypt.
