Diagnosis of Energy Efficiency in Public Lighting: Luminotechnical Study

Objective: The aim of this article is to evaluate and optimize the public lighting system at the Federal Rural University of the Semi-Arid (UFERSA), Angicos Campus, in order to promote a more efficient and sustainable management of the energy consumed on site. Theoretical Framework: The theoretical framework is based on concepts of energy efficiency applied to urban infrastructure, with an emphasis on the public lighting standards established by NBR 5101:2024. Method: The methodology adopted includes data collection on the existing lighting points on campus, such as the number of light points, types of lamps, power, and luminous characteristics. The evaluation follows the guidelines of the NBR 5101:2024 public lighting standard. Results and Discussion: The initial analysis highlights the potential for energy consumption reduction through system modernization. Implementing more efficient technologies, such as LED lamps, can significantly reduce energy consumption, generating considerable savings for the university and the local community. The discussion suggests that adopting innovative solutions, such as motion sensors and automated systems, is essential for energy sustainability in educational institutions. Research Implications: The research on optimizing public lighting at UFERSA Angicos Campus highlights the positive impact of system modernization with the adoption of efficient technologies like LED lamps. This can reduce energy consumption and operational costs, serving as a model for other institutions and urban areas. The research emphasizes the importance of sustainable solutions and efficient electricity management, promoting replicable practices for sector transformation. Originality/Value: The originality of this study lies in the practical application of the NBR 5101:2024 guidelines in the specific context of a university campus, providing a replicable model for efficient public lighting management.
