Buildings are significant contributors to global energy consumption and environmental impact, with the European Union reporting that buildings account for 40% of overall energy usage. To address this, energy management systems (EMS) in buildings have gained traction, aiming to optimize energy supply and demand while maintaining occupant comfort. This systematic literature review examines the current research landscape on energy efficiency in building EMS. It identifies key areas such as interdisciplinary integration, challenges like insulation optimization and energy standards for appliances, and the importance of thorough energy audits for reliable data collection. The review underscores the critical role of EMS in reducing energy consumption, optimizing comfort, and integrating renewable energy sources. It also stresses the need for raising awareness among occupants and constructing energy-efficient buildings. Overall, the review highlights the significance of EMS in enhancing energy efficiency and reducing energy consumption in buildings, emphasizing the imperative for further research and development in this field.
