Abstract: Success and quality of thermal building simulations strongly depend on consistency, correctness, and completeness of BIM data. Therefore, it is necessary to check in this context the content of openBIM data before transferring it into a respective simulation tool. With the buildingSMART standard Model View Definition XML (mvdXML), exchange scenarios can be formalized which are testable with software tools. In the present paper, the current capabilities of mvdXML rules are analyzed and a first approach of Model View Definition (MVD) rule sets to cover exchange requirements for thermal building simulations is introduced, including formalizing the MVD rule sets as mvdXML. Using an additional module of the software application FZKViewer, the defined rule sets are validated and tested in an openBIM workflow for thermal building simulation.
