【 摘 要 】

The growing elimination of resources calls for a paradigm shift from linear material consumption to circular economy - especially in the construction industry. The residential and research unit Urban Mining and Recycling (UMAR) in the modular experimental building NEST of Swiss research institute Empa consequently implements this claim: The design by Werner Sobek with Dirk E. Hebel and Felix Heisel is constructed from separable, ingrade material resources that are completely reusable, recyclable or compostable. The concept of cycles therefore plays a central role: Utilized materials are not consumed and then disposed of; instead, they are borrowed from their technical or biological cycle for a certain period of time and later returned to these material cycles. Considering its many reclaimed material resources, the apartment is a built example of urban mining. Designed for disassembly at the end of its service time, UMAR also represents a material depot for future projects: Instead of connecting elements and components irreversibly through wet connections such as chemical glues, UMAR uses screws, clamps or interlocking systems in order to recover all used substances ingrade and sorted. UMAR is both temporary material depot and material laboratory - while proving the claim that it is possible already today to build within a circular system.
