Objective: Through a literature analysis and a case study at a university, this study seeks to examine the efficacy of energy management systems (EMS) applications in the context of green buildings. Theoretical Framework: The “Renovation Wave” policy encourages energy-efficient renovations in public buildings. EMS are key tools for improving energy efficiency and supporting renewable energy use in buildings. Method: A systematic literature review of scientific articles from 2013 to 2024 was conducted using Scopus, Web of Science, IEEE Xplore, and ScienceDirect databases. Thematic content analysis was used to assess the technical capabilities, energy efficiency results, technological integration, and interaction with user behavior of EMS. Results and Discussion: Using EMS to control lighting and HVAC automation can result in CO2 reduction and energy savings of up to 25%. In the case study, lighting has been cut by 25%, HVAC systems by 22%, and overall electricity use by 18%, resulting in an annual reduction of 130 tons of CO₂ emissions. Additionally, the use of user-oriented display panels and the integration of photovoltaic panels have enhanced behavioral interaction and the renewable energy usage. Research Implications: Students' and staff's energy awareness has increased by 47% as a result of these panels' real-time energy data. The multifaceted contributions of EMS that reinforce the connection between energy efficiency, digital transformation, and environmental responsibility are revealed. Originality/Value: The research's unique contribution is the mixed methodology combining field data, systematic literature synthesis, and a sample EMS model that can be modified for use in educational settings.
