The purpose of this Course Unit is to be able to design an energy management system for a building. This requires: to understand the physical phenomena and be able to model the static and dynamic behaviour of a building system for its energy management to be able to model the internal inflows and solar gains to be able to model the impact of the occupation and the comfort felt by customers to ba able to reset the parameters of a building model based on a measurement campaign to know the technology Building Management to be able to design a heuristic energy management system to be able to design an approach based on optimization to discover software tools for building energy management
