In this study; the possibility to interface a commercial building simulation tool with Modelica models is investigated. In this application; the zonal model VEPZO – modeled in Modelica – is coupled to the software TRNSYS – mainly programmed in Fortran – to be able to perform a dynamic co-simulation. The objective of this coupling is to obtain refined airflow and air temperature prediction; while retaining com-putation effort low enough to allow for transient computation. In a first attempt; a coupling using FMI was tested without success due to a lack of adequate solvers for FMI export. Therefore; a script coupling was implemented. Further steps include a validation and evaluation of the programmed interface and the results of the coupled system in respect to computation time; quality of results; usability and further development.
