Graphic representation of a digital twin
Graphic representation of a digital twin connected to real-time metering data from a building. The digital twin runs in a cloud. With the so-called State Estimator, the simulation model is continuously adapted to the current measurement data from the building.

Time series with forcing terms
Time series of an experiment where the digital twin was adapted to the measurement data using forcing terms. At the beginning of the experiment, the measured and simulated temperatures do not yet match. After that, the differences between the two values are very small. See also other image showing the heat sources and sinks needed for this.

Calculated heat sources and sinks for the digital twin
Time series of an experiment where the digital twin was fitted to the measurement data using forcing terms. The graphic shows the required "Forcing Terms" = heat sources and sinks. See also the other graph with the associated measured and simulated temperatures during the experiment.
