Intelligent management strategies to optimize building energy consumption are considerably gaining attention due to the current climate challenges and the technological evolution of the automation solutions. To tackle the new energy efficiency standards, building energy management systems must be able to control energy consuming devices in order to minimize the costs and optimize the comfort of occupants. In this thesis, we study hybrid multitime scale model predictive control strategies to tackle building energy management problems. We proposed a two-layer hierarchical controller to jointly control the energy consumption and power demand of the system. The upper level implements a long term economic optimization that takes into account the...
