Problem
In the BoundaryConditions-package, different weather models exist. In the example models of the high order modelling approach of thermal zones, old weather models are used to calculate solar radiation on tilted surfaces. A comparison between the IBPSA weather models and the old weather models contained in AixLib shows a higher accuracy of the IBPSA weather models. As the old weather models use the interface model SolarRad_out and the HOM uses the interface model SolarRad_in, we have to find a solution for the connection of the IBPSA weather model (real outputs) with the HOM (SolarRad_in model).
Suggestion for solution
Replace the old weather models by the IBPSA weather models
replace the SolarRad_out and SolarRad_in models by heatPorts OR keep the SolarRad models and implement a model for real value to SolarRad_out, something like this:
Additional comments
As the results will probably change due to the change of the weather model, we have to update the result files for the room temperature of the validation models.
