Abstract

In this white paper, the specific requirements for the application and approaches of the BIM method in existing buildings, which were determined in the workshop “BIM in existing buildings - challenges in renovation” as part of the scientific accompanying research on energy transition construction (digitalization module), are presented and discussed. In addition to the results of a thesis discussion, which was supplemented by statements from the literature and from the lectures, important technologies for building inventory are briefly presented in the introduction. In the discussion, the participants clearly agreed (\> 75\%) with the following theses: • 1st Thesis - With the help of the BIM method, renovation tasks can be carried out more efficiently. • 2nd thesis - BIM in existing buildings is not the state of the art. • 4th Thesis - Standardized restructuring processes are possible. • 5th Thesis - Machine learning (ML) and artificial intelligence (AI) are important technologies for the automated creation of BIM models. or rejected: • 6th thesis - Obtaining information for the creation of a BIM model is possible for almost all buildings without mechanical intervention (non-destructive testing). The third thesis, “The use of the BIM method in existing construction is more important than in new construction,” revealed a more differentiated opinion. The evaluation of affirmative or negative arguments for the theses revealed a chicken-and-egg problem in a similar way to the application of the BIM method in new buildings. Due to the low distribution, there is little accessible knowledge for application, few proven success stories and there is a lack of necessary data and experience, which makes getting started difficult and motivation low. In addition to the challenges for the application of the BIM method in general or in new buildings, there is a need for an inventory when applying the BIM method in existing buildings. Machine learning or artificial intelligence methods can have great potential for automated data merging to create or enrich a BIM model. However, there is a lack of trained staff (including teachers) and training data. As with the use of the BIM method in general or in new buildings, the BIM method is seen as a communication tool that leads to more transparency and better results due to the broader data basis.
