Transient building and system simulation - hardware in the loop

Technology development through the coupling of reality and simulation.

In addition to evaluating applications through scientific measurements, depending on the task we also use different simulation tools. Our services encompass

  • Multi-zone models
  • Different types of buildings for residential and administrative building applications
  • A wide range of plant components, storage systems and transfer systems
  • Extensive models for usage scenarios
  • Metrological validation of (component) models if desired
  • Real tests coupled with simulations in a hardware-in-the-loop environment

Thanks to powerful simulation tools, we can transfer measurement results from our detailed experiments on test rigs to entire buildings or to other climatic locations, for example. In addition, they are helpful when it comes to evaluating the influence of different usage scenarios or make it possible to assess different variants and boundary conditions, which would require far too much time and money in real-life tests.

Using the measurement data from our tests, the simulation models can be validated and optimized. Reliable simulation results are ensured by a high quality of the models and thus the ability to accurately replicate the real behavior in the simulation.


By coupling real experiments with simulations in a hardware-in-the-loop environment, we can further extend the range of investigations. For example, a real heat pump in a test rig can be coupled with different types of buildings, different primary sources (earth probe, ice storage) or variable usage scenarios from a simulation running synchronously in time, in order to efficiently evaluate their influence on the system.
