Digi-HBV - Topology-optimised reinforced concrete slabs with digital formwork and reinforcement

Digi-HBV delivers a reusable, material-efficient floor system that combines ecological impact with industrial feasibility. Core innovations include interlocking, CNC-milled timber dowels for the timber–concrete interface, demountable joints to ensure in-plane (diaphragm) action, and a generative, LCA-coupled file-to-factory workflow. Full-scale load tests verify load-bearing capacity, durability, and demountability. The outcome: at least 50% lower manufacturing emissions, significantly shorter construction times, and a scalable product for climate-neutral, circular construction.
