Non-invasive sensors and sensor networks are key technologies for efficiently achieving this goal, since it is of utmost importance that existing hydraulic systems are not changed and the engineering effort for installation remains minimal. This paper presents a data-driven approach that should allow low-cost installation of sensors at arbitrary points of the building and then retrieve the structure of the hydraulic system from the recorded sensor values. The architecture as well as first preliminary results from field test buildings are presented.eninfo:eu-repo/semantics/closedAccessenergy monitoringbuilding analyticsnoninvasive sensorsclamp-on temperature/flow sensorinfo:eu-repo/semantics/conferenceObject10.1109/ISIE.2018.8433768
