System Simulation

The BuildingSystems library supports a detailed modelling of real building energy systems. The structure, the physical behavior and the functionality of a real system can be reflected by a so called "Digital Twin" (The used method is described in NytKauKha2018).

Features

  • Good understanding of complex building energy systems by using sub models on multiple hierarchy levels.
  • Use of virtual sensors for comparisons with the real technical system.
