Abstract

This study analyzes the economic feasibility of an energy efficiency project at the Federal University of ABC (UFABC), using a traditional engineering economics indicator, the discounted payback period. Energy consumption and costs from electricity bills were analyzed for the period from 2018 to 2023, covering both pre- and post-intervention scenarios. The results showed a 24.30% reduction in energy consumption and a 28.35% cost savings. The discounted payback was calculated under three scenarios, with discount rates of 5%, 10%, and 12%, resulting in payback periods of 5.19, 6.06, and 6.5 years, respectively. Additionally, further scenarios were projected, considering variations in energy tariffs and consumption, demonstrating the project's robustness even under less favorable conditions. The analysis suggests that the project is economically viable, with significant benefits for the institution and the environment. However, it is recommended that future studies incorporate a more detailed assessment of operational and maintenance costs, as well as long-term impacts, for a more comprehensive understanding of the project's feasibility.
