Durable Data Models for Circular Building Practices in Bio-based Construction – the History Stack

Circular building practice involves creation, maintenance, repair, and reuse of components. This positioning paper highlights the lack of digital models for such practices and proposes the History Stack framework for sustainable bio-based building economy. It advocates avoiding monolithic data models in favor of flexible structures reflecting dynamic changes. Key elements include access to foundational data like material sources, fabrication methods, and design logics, ensuring adaptability throughout a building's lifecycle. The History Stack links diverse digital models, supporting the evolution of practices and heterogeneous data types aligned with EU intentions for the Building Logbook and next-generation BIM-like systems.
