Table 2 Synthesised D5 Workflow from case studies and enabling technologies to upscale the reuse of building materials (as explained in “Methods”)
1. Detection | 2. Disassembly | 3. Distribution | 4. Design | 5. Deployment | |
|---|---|---|---|---|---|
To fully upscale reuse from the existing building stock, we need to: | Identify buildings pre-demolition | Invent materials for post-disassembly sorting | Give materials an identity for new construction sites | Design with the available stock of reused materials | Fabricate buildings with bespoke reused materials |
Methods | Data and image processing to identify material stock in cities | Geometry and material identification | Database management for tracking, tracing and trading | Human-machine interaction for creativity support | Connection fabrication and assembly |
Digital technology | • ML • CV | • Reality capture • Scan-to-BIM • CV • XR | • DPPs • Tracking and tracing technologies • Blockchain | • Generative AI • Computational design algorithms | • Additive & subtractive manufacturing • XR |
Case studies | • Zurich City | • Geneva warehouse • Zurich music pavilion • K118 | • Database of disassembled timber beams for reuse in domes | • Dome 5.1 • Dome 5.2 | • Dome 5.1 • Dome 5.2 • Dome 5.x |
