“…In this paper, a complete methodology of modeling/ controlling a multi-zone office building is proposed, the objective is to improve the hygrothermal comfort of the occupants while minimizing the energy consumed. The modeling step, which is essential for the design of a MPC, is based on a physical description of the building [6]. Knowing that each control action will be associated with a different descriptor state-space model of the system, the predictive control strategy will be of the hybrid type.…”

This article treats the problem of modeling and controlling a multi-zone office building to ensure its hygrothermal comfort through optimal and cost-effective management. An analysis of the hygrothermal behavior is carried out, which leads to a set of descriptor state-space models. Based on this modeling, an iterative optimization algorithm is proposed to solve the optimization problem associated to the model predictive control (MPC) design. By means of an original cost function based on peak/no peak energy consumption, significant energy savings can be envisaged in practice.
