Worked on enhancing building energy modeling capabilities across the RWTH-EBC/AixLib and TEASER repositories, focusing on radiative heat exchange and interzonal heat transfer. Re-enabled radiative heat exchange modeling between indoor surfaces in AixLib by reintegrating thermal conductor components, improving the fidelity of thermal zone simulations. Implemented adjacent zone connections and interzonal heat flow in OpenModelica, refining parameter definitions and connections for more accurate building physics representation. Cleaned up obsolete code to streamline maintenance and data handling. Updated TEASER’s example scripting in Python and Modelica, aligning it with the development branch and improving data loading for construction and type elements.
