An Information Management Framework for Multi-Use Case Building and District Digital Twins

Abstract: Digital twins are increasingly being adopted in the built environment to support data-driven operations, optimisation, and lifecycle decision-making. However, most current implementations remain limited to single use cases and centralised architectures, constraining scalability and interoperability at building and district scales. This paper proposes a use-case-driven information management framework for multi-use case building and district digital twins. The framework combines a layered architecture with a dual semantic modelling strategy that separates stable, standards-aligned core models from flexible, use-case-specific extensions. The applicability of the framework is demonstrated through a real pilot, illustrating semantic alignment to support multi-use case integration.
