iBECOME both anticipates and augments the digitalization, decarbonization and decentralization of the energy system. By utilizing engineering fundamentals tools and sophisticated data analytics techniques it processes and transforms building and operational data into commodities that can be monetized through the offering of energy services in the framework of innovative business models. Particularly, iBECOME will demonstrate the functionality and viability (technical and economical) of a virtual BMS platform deployed as a SaaS solution that can optimise the energy performance, comfort conditions and flexibility potential of buildings and facilities while allowing 3rd parties to interconnect for providing other energy or non-energy related services. The vBMS will utilise a calibrated physics-based simulation model to allow accurate predictive control for energy and comfort optimisation, flexibility maximisation and precise M&V for both implemented Energy Conservation Measures (ECMs) and Demand Response (DR)
