Minimizing the energy consumption of residential buildings while providing maximal thermal comfort is a current challenge. In this paper a smart home management system is proposed which is able to globally optimize the thermal and electrical systems of a modern smart home, instead of locally optimizing each subsystem alone. The used controller consists of a mixed-integer quadratic program (MIQP) used in a model predictive controller (MPC) scheme. The MIQP-MPC is capable of handling multiple energy sources, respecting external grid-based constraints, as well as handling the electrical heating systems. Furthermore, extensive dis-turbance prediction methods for the most influencing external and internal disturbances of a smart home are presented. Those disturbances are ambient temperature, solar irradiation and occupancy. With the predictions of the future occupancy, the MIQP-MPC is also able to heat the building only when needed. The MIQP-MPC can help future smart grids to reduce the peak loads and can act as an energy storage, if grid-side energy production is high. An-other feature of the proposed controller is a simple-to-use interface for the end-user. This interface enables the end-users to tune the controller in an intuitive way to their individual demands. Therefore, the end-user is able to balance the partially conflicting goals of the MIQP-MPC. Those goals are the reduction of running costs, the maximal usage of renewable energy sources, and the minimisation of the temperature deviation from the set point.
