The integration of Building Information Modeling (BIM) and Building Energy Modeling (BEM) approaches is highlighted as crucial for enhancing energy efficiency. The proposed workflow involves four steps: i) collection of building data through documental analysis and on-site surveys; ii) the construction of a BIM model and its production in Industry Foundation Classes (IFC) standards, including thermo-physical parameters; iii) the developing the BEM model; iv) the creation of a Virtual Reality (VR) interactive environment. The methodology is tested on an office building at the University of Rome Tor Vergata, built in the 1980s. Key outcomes include verifying data interoperability, optimizing energy simulation processes, and enabling interactive exploration of energy data through VR techniques. This integrated approach reduces errors, time, and costs, while also serving as a decision-making support tool for building managers and an educational tool for energy design awareness. The study presents a scalable workflow for energy building management and lays the groundwork for innovative digital twin development for buildings and structure. Pages: 141 - 148 Paper:
