SZTAKI researchers participate in the development of a European scalable Building Information Model (BIM) based decentralized knowledge platform

80% of Europe's buildings will still be in use in 2050. Action is needed to preserve their integrity and value. Modern countries generate an incomparable amount of data and information about the building stock, such as 3D geometry data, operational information, measurements, etc., which are usually lost or unused, unstructured and not updated. The vision of the EU-funded BUILDCHAIN project is that this information and data have the potential to change the way we design, construct, and maintain our buildings.

BUILDCHAIN will create a scalable BIM-based decentralized knowledge platform to digitally identify, register, update, and analyze massive amounts of data related to the overall life-cycle of buildings based on Origin Trail Decentralized Knowledge Graph. The BUILDCHAIN project will design and develop its own Digital Building Logbook solution for the integration of building data and knowledge, and the inclusion of new applications and functionalities dealing with integrated information, efficiency, circularity and transparency to improve the building stock, facilitate informed decision making and its validation.

The role of SZTAKI in the project is to develop AI based solutions, data-driven models for different building-related problems mainly focusing on structural health and behavior. SZTAKI participates in developing a tool to update simulation models based on IoT sensor data using Bayesian techniques generating a digital twin of the structure. Furthermore, SZTAKI coordinates the first design phase of the highly multidisciplinary project.

The coordinator of the BUILDCHAIN project is University of Pisa, further consortium members are University of Granada,  ZAG (Slovenian national building and civil engineering institute), University of Ljubljana, Athens University of Economics and Business, Prospeh, Rina Consulting, Bexel Consulting, Protim Rzsisnik Perc, Clio and the Municipality of Florence.
