Wall against soil: Perimeter insulation and sealing
Maximilien Ast | 12.10.201611
Construction example
Status Quo: Cradle to Cradle® Alternative:
Problem:
insoluble material compound
no recycling possible
toxic materials
no access
Approach:
Waterproof concrete vs. concrete + bitumen
Wallbag with foam glass gravel vs. XPS (material
made from scrap glass, 100% recyclable)

Solutions FacadeModular building and separation of functions
Quelle: V. Brenner, Universität Stuttgart, 2010
Problem:
up to 20 unseparable material layers
non recyclable toxic waste
high pollution
Approach:
Demountable construction
Separable material composites
Separation of functions = flexibility in adaptation
f.ex. Curtain facade, Element facade,…
