Title: From BIM representation to functional simulation and real time advanced control.

Residential Building Digital Twin functional representation requires a new professional role (BDT Simulation Manager). This functional aspect of the building digital twin covers all phases of the building, from design and concept to commissioning and real time management. It must be well coordinated with BIM and other services of the BDT.

Mathematical simulation can reproduce unctionalities of the different systems: passive building, ventilation networks, heating and cooling devices, meteorology and occupancy. Advanced Software in the Loop embedded in supervision and control devices can improve drastically the visibility of health, comfort and energy parameters. Performance contracts (as one economic implication) can make use of dynamic energy evaluations. Maintenance can be carried out effectively thanks to extra parameters derived from simulation, affecting not only equipment but networks and sensors.
