| dc.description.abstract | Artificial lighting powered from non-renewable energy sources is a major contributor to energy consumption, greenhouse gas emissions, and environmental pollutions. In buildings, lighting systems account for a significant share of total energy use. The demand for energy is rising daily due to population growth, lifestyle changes, and technological advancements. This surge in demand has triggered an energy crisis, particularly alarming for developing countries like Ethiopia. This crisis has profoundly affected daily life, business operations, and building construction. Therefore, it is crucial to optimize the use of available electric energy sources by adopting new, highly efficient lighting control systems to bridge the gap between gross power production and the nation’s energy demand. This research study work examines the use and functionality of presence-based intelligent lighting control and daylight harvesting systems installed in the tallest structure in East Africa, the Commercial Bank of Ethiopia Headquarters (CBE-HQ). To evaluate system effectiveness, actual lighting energy consumption measurements and comparisons with other traditional lighting control approaches were carried out. According to the results, the CBE-HQ daylight harvesting system saved 79.88% more energy than fluorescent lighting systems and 59.76% more than conventional Light Emitting Diode (LED) systems. Similarly, compared to conventional LED and fluorescent systems, the presence-based lighting management system reduced energy consumption by 44% and 72%, respectively. Beyond substantial energy savings, the study reveals that the intelligent lighting control systems also considerably decreased the building's potential carbon footprint, reducing annual CO₂ emissions by about 50 tons when compared to ordinary LED systems and 138 tons when compared to fluorescent-based lighting systems. The study recommends design reconsiderations, policy interventions, public awareness and education, regulatory measures, research and development support, and international collaborations to advance the adoption of state-of-the-art lighting technologies and enhance national energy efficiency efforts. | |
