Abstract: This paper presents a methodology aimed at facilitating the deployment of model-based predictive control (MPC) in buildings. MPC has shown promise as an effective way to reduce utility costs associated with peak demand, and to better manage the interaction between “smart buildings” and the “smart grid”. However, steps are needed to streamline the implementation of MPC in buildings and thus encourage its adoption in building operation. The proposed architecture intends to contribute to this goal by enabling a “compartmentalized”, distributed, hierarchical approach to building modelling and controls. The proposed multi-level methodology allows formulating control problems so that the planning time horizon fits the scale of the system. A model of a commercial building, including thermal energy storage devices at different control levels, is used to demonstrate the methodology. Low-order resistive-capacitance models for the thermal spaces are obtained from a detailed model created in EnergyPlus.
