Core offering

BDTA is a membership-based non-profit association that develops and disseminates frameworks, ontologies, and standards for Building Digital Twin Environments. Its core offerings include the BDTA Ontology Catalogue web platform, the annual Building Digital Twin International Congress (BDTIC) and Scientific Conference (BDTSC), a portfolio of research assets and certifications produced across four working areas, and leadership of European standardization efforts such as EN 18162:2026 and the Kaunas Declaration.

Product overview

Building Digital Twin Association (BDTA) is a membership-based international association (ASBL, Belgium) that shapes the future of the Building Digital Twin industry rather than offering a single unified software product. Its primary offerings include: the BDTA Ontology Catalogue — a public web platform for discovering and accessing building digital twin ontologies; the annual Building Digital Twin International Congress (BDTIC) as its flagship conference series; the Building Digital Twin Scientific Conference (BDTSC) as an academic counterpart; and a portfolio of working-area research assets, certifications, and publications across BDTE definitions, open technology frameworks, vertical aggregation, and simulation across the building lifecycle. BDTA also coordinates standardization efforts (e.g., CEN/TC 442/WG 9) and initiatives like the Kaunas Declaration for Digital Building Permits.

Products and services

• BDTA Ontology Catalogue The BDTA Ontology Catalogue is a public web-based catalog platform that enables discovery, exploration, and access to ontologies relevant to the Building Digital Twin domain. Developed by BDTA Working Group 2, it serves as a centralized hub for collaboration, reuse, and knowledge exchange across the building digital twin industry.
• Building Digital Twin International Congress (BDTIC) BDTA's flagship annual international congress convening researchers, industry leaders, public authorities, and technology innovators to discuss Digital Twin trends, challenges, and innovations in the built environment. Editions have been held in Barcelona, Antwerp, Kaunas, and Brussels.
• Building Digital Twin Scientific Conference (BDTSC) An inaugural scientific conference launched in 2025 alongside BDTIC, focused on academic research and early-career researchers in urban digital twin technology, with a PhD Spring School held in conjunction with the event.
• BDTA Working Areas & Research Assets A portfolio of BDTA research, certifications, and specific assets developed across four working areas: BDTE Definitions & Roles, Open Technology Framework, Vertical Aggregation, and Simulation Across Building Lifecycle, driving development of the Building Digital Twin sector.
• Kaunas Declaration on Digital Permitting Standards The Kaunas Declaration provides a consensus framework for digital permitting standards in Europe, addressing processes, technology interoperability, safety, social inclusion, fairness, and training across BIM-GIS integration and public participation processes for building permits.

Broad incumbents

• Bentley Systems: Major infrastructure engineering software provider supporting BDTA's Kaunas Declaration and KGSWC conference. Their iTwin platform is a direct commercial digital twin ecosystem overlapping with BDTA's interoperability mission.
• Autodesk: Global provider of BIM, CAD, and digital twin software (Revit, Tandem) widely used across the built environment. Autodesk's commercial platforms compete in the same digital twin ecosystem that BDTA seeks to standardize.
• Digital Twin Consortium: Object Management Group-hosted global consortium that sets digital twin definitions, taxonomy, and interoperability frameworks across multiple industries. BDTA references it as a partner for bridging European and global digital twin initiatives.
• European Committee for Standardization (CEN): Official EU standards body that published EN 18162:2026 under technical committee CEN/TC 442, with BDTA's President serving as Convenor of WG 9. CEN is the meta-organization whose standards confer regulatory standing across the EU.

Direct peers

• buildingSMART International: Global non-profit standards body for openBIM, working on interoperability standards (IFC, bSDD) that directly intersect with BDTA's building digital twin and ontology work. They are a primary collaborator through the CEN/TC 442 ecosystem.
• Open Geospatial Consortium (OGC): International standards consortium for geospatial and location standards, actively collaborating with BDTA on BIM-GIS integration and semantic web standards for digital twins. Their API and data standards underpin building digital twin interoperability.
• REHVA (Federation of European Heating, Ventilation and Air Conditioning Associations): European federation of HVAC engineers with 120,000+ members across 25 countries. BDTA was incorporated into its BICEM group in 2024, and both bodies collaborate on building energy modelling certifications and digital twin simulation.
• Metabuilding: European innovation network for the construction and built environment sector. BDTA signed a collaboration agreement at SCEWC 2025, and both organizations address adoption of digital tools across the construction value chain.
• European Construction Technology Platform (ECTP): European Commission-recognized research and innovation platform for the construction sector. BDTA co-organizes BDTIC 2026 with ECTP, and both bodies coordinate research priorities and standardization across the European built environment value chain.
• Industrial Digital Twin Association (IDTA): European association focused on the Asset Administration Shell for industrial digital twins, with which BDTA signed a strategic MoU in 2025. They share a structural mission — domain-specific digital twin standardization — and BDTA extends AAS into the built environment.
