Abstract: Detailed construction and building component models, including hygrothermal porous material transport models, can be used to model a large variaty of modern energy transfer and storage systems. These include heated concrete slabs, shallow soil heat collectors, heated wall layers, combined photovoltaic and construction panels etc. The interaction with connected HVAC systems/energy distribution systems and/or control models is, however, often limited in such tools. With the use of the FMI runtime tool coupling standard, it is possible to connect detailed component models with other simulation tools. This is illustrated in the article using the hygrothermal transport model DELPHIN. The article first describes the FMI co-simulation interface of the tool. Then, the generation of control model FMUs is shown using open-source technology for FMI generation (OpenModelica, FMICodeGenerator). Using MASTERSIM as co-simulation master, the setup of an application case (heated concrete slab) is illustrated, including two ways of manually generating control model FMUs.
