Digital Twin systems for building façade elements testing

Abstract: This research is part of the MetabuildingsLabs project on Open Innovation Test Beds, aimed at providing a platform for open source, open access and open data for technology providers, with a focus on building facades. Within this paper, we adapt the digital twin paradigm for a façade testing facility, using open tools. We formulate a conceptual system architecture based on previous research, with the key particularities of testing beds and the system end-users. We describe key software and IoT components and the role of semantic models. The approach is demonstrated on a scaled-down 3D-printed model of the planned building.
