Abstract: Model parameterization is a time-consuming and potentially error-prone task, in particular for large simulation models. While still many parameterizations are executed manually, we present a uniform method to minimize the parameterization effort and apply it to building energy systems. Using heat and temperature demands as input, we quantify the remaining parameters with physics-based relationships. Input parameters are either scalable or known by experts. Applying the presented method, the number of parameters decreases by 86 %. This decrease essentially reduces the implementation effort and the number of potentially incorrect parameters. Thus, we provide parameterizations of building energy systems with minimal effort.
