"Calibration and validation of a solar thermal system model in Modelica";
Recent advancements in the domain of modeling physical processes offer opportunities to use
equation based modeling environments, such as Modelica, for the simulation of building heating,
ventilation, and air-conditioning (HVAC) systems. The current work demonstrates Modelica
capabilities in a case study of real building solar thermal system simulation. The simulated system
is part of an innovative ENERGYbase building, designed according to the so called Passivhaus
standard. Model calibration and validation procedure is developed to include optimization based
parametric adjustments of component models using the monitoring data during a single week.
The calibrated system adequately reproduces half a year of real system operation. Future work will
concentrate on application of the developed calibration and validation methodology in the whole
year overall building energy simulation.
