Abstract: As global energy consumption continues to rise, it is essential to adopt measures that regulate electricity use while still meeting the demands of modern society. These efforts align with the United Nations Sustainable Development Goals and are supported by various organizations. This study applies a methodology that combines the implementation of a Level 2 Energy Audit with the evaluation of the Electricity Consumption Index (ECI) at the Department of English of the Multidisciplinary Academic Unit of the Altiplano Region, Universidad Autónoma de San Luis Potosí. The study identifies strategies to reduce electricity consumption related to lighting systems and equipment operation throughout the department. Additionally, it assesses the percentage of users who promote and practice energy-saving habits. Key recommendations include transitioning the lighting system to LED technology, expected to reduce electricity consumption by 15, and implementing power factor correction measures, projected to yield an additional 6.17% in energy and cost savings. Together, these strategies could result in an estimated annual electricity savings of 21.17%, making them attractive to institutional decision-makers. Furthermore, by comparing the department’s ECI with a reference index established for educational institutions in temperate climate regions of Mexico, the study determines whether the proposed strategies should be implemented immediately or planned for the medium to long term. This decision-making framework represents the main contribution of the case study.
