Lesson 1: Circularity and adaptive reuse (M. Rinke & F. Van De Voorde)
- consumption:
-> model 1972 – how long planet can maintain various existing systems
- annual global CO² emissions: 47% construction (27% building operations; 10% materials &
construction; 10% other construction industry)
- circularity as a principle: what circulates: 3 layers
1. materials – minimizing/ changing material use
- what material used -> different effect – emissions
- Recycled concrete -> issues:
- constricted, not as strong
1) uncertainty composition
2) uses ++energy – crushing, new cement…
-> used in foundations, basements
- recycling on site: reuse of raw materials and components
-> Prefab concrete elements
-> Hempcrete with locks
-> timber skeleton construction
- less flexible, not v durable (reuse)
- ex. Hotel Jakarta, amsterdam: prefab rooms timber -> ++ fast
- issue: building cannot change plan (all walls are bearing)
- not durable
- changing material use: slabs – most energy intensive-> reduce slabs = -- energy
- general types of concrete-timber hybrid floors:
- concrete-timber-steel floor sys: concr often necessary (fire, accoustics)
- insulation: - cork: rot-resistant
- sheep wool: sound insulation in dry walls
1
, 2. components – reuse of components
- reuse within the construction value chain (circularity)
- ROTOR DC, Bru: material collection – buildings as material banks
- get few weeks to claim all valuable items b4 demolition
- Ephemeral Permanence June ’22 – M. Rinke, UA & 2 others
- ex. Head Building of hall 118 – Winterthur ( CH) baubüro in situ
- on top of existing building – adaptive + material use
- consideration – condition materials (how usable) – research how open
ended reuse (how materials stay reusable future) – permanent temporary
- some parts – less reusable future -> concrete - fire prot & acoust
- design for deconstruction (DfD): theoretical concept – open ended reuse
- easily repair – less ‘throw away culture’ -> ex. Cars
- translate to building logic -> how do with high energy materials
- principles:
- reversible connections: allow simple maintanance & deconstr
-> neg: takes ++ time, ++ know-how needed
- extra elements -> ++ energy
-> pos: ++ durable (reuse)
- Structurez: knopen, Japans: hang timber beams on
collums and lock
- wikihouse: timber clicksystems (w bolts) ->
- bolts – often used – temporary
- ex. Temporary courthouse Amsterdam, cepezed
- no on-site pour, all components can be taken apart
- dismountable
- peikko: systems inside concrete
