Modelica has been used extensively within the Thermal System Simulation (The SySi) research group at KU Leuven to simulate and optimize the control and design of building energy systems. Within this scope, the open source Modelica library IDEAS has been developed and papers have been published that explain how IDEAS can be used to develop fast simulation models and MPC. This paper presents an open-source simulation model of a terraced house for which these earlier presented guidelines are applied and for which MPC results are made available. A full-year simulation of the nine-zones model takes four minutes and energy savings of 12.8 % are reported compared to a current-practice rule-based controller, although MPC has thermal comfort violations of up to 0.4 K.
