Summary
With the optimization of the planning, commissioning and operation of buildings to save energy and resources, the digitization of these processes takes on enormous significance. The use of analysis models is the central task here. The widespread use contrasts with very complex processes for model development. These models are individually adapted to the object under consideration at great expense, and their reusability is severely limited. FMI4BIM will investigate and standardize the use of existing models and processes in order to significantly increase the degree of their reuse in different planning stages. At the same time, the development of future models is to be simplified and made technically widely applicable. As a solution approach, the project pursues the research and development of both a semantic-physical and a software-technological model interface for analysis models, so that models from different suppliers can interact with each other and be aggregated into building models. Standards will be created for the design of the interface. On the software-technological side, the FMI standard will be used. The intellectual property of the model developer is protected, which promotes the model exchange including the establishment of adequate business models. In addition, the interfaces from the physical side are to be made more uniform, which will allow the use of different models in the form of interchangeable components to perform analysis tasks within BIM processes. Standardization of the approach as a separate BIM process is envisaged. The use of uniform test and verification environments for standardized models also guarantees a significant increase in model quality. FMI4BIM makes an important contribution to the implementation of digitization in the construction and building industry.
