Radical recycling
LUMI, Uppsala (SE)
In Uppsala (SE), the Lumi project shows how the future can be built without demolishing the past. “Reuse” is the magic word: almost everything is recycled, from the foundation to the toilet bowls.
A former administrative complex built in the 1970s is slated for demolition. But thanks to a radical rethink, this problem case is transformed into a showcase project for sustainability.
105 tonnes of plasterboard, roof sheets, bricks, doors, cupboards and toilets – everything is dismantled, processed and reused whenever possible. Three previously separate building sections are joined together by a shared inner courtyard to form a new whole. Photovoltaic panels on the roof and solar cells in the facade provide green energy, and rainwater is used for flushing the toilets.
Geberit FlowFit is used as a supply system, for example for the toilet flushes. The flow-optimised press fittings allow for the use of smaller pipe dimensions – this reduces the demand for raw materials in the building.
No compromise on quality
«Statt abzureissen konnten wir 80 Prozent der Struktur erhalten und drei zusätzliche Holzgeschosse aufsetzen», sagt Jonas Wahlström, Projektleiter bei der Immobiliengesellschaft Vasakronan, die Lumi entwickelt hat. Doch bedeutet Wiederverwertung Abstriche in der Qualität? «Ich kenne Beispiele, bei denen altes Material hochwertiger ist als neues. Wenn man die richtigen Dinge wiederverwendet, ist das Ergebnis genauso gut.»
