【 摘 要 】

The growing scarcity of resources calls for a paradigm shift from linear material consumption to circular economy - especially in the construction industry. This shift involves a complete rethinking of design principles, materials, construction technics and technologies, as well as the introduction of new business models evolving from these reconfigurations within the field. This paper will show on-going research on these themes with a focus on direct material re-use and recycling through the discussion of a prototypology - the recently concluded Mehr.WERT.Pavillon (MWP) at the BUGA 2019 in Heilbronn. The research specifically addresses a reversible, mono-material structure that is made from re-used structural steel and recycled glass. The concept of cycles therefor is significant: Utilized materials are not consumed and disposed of; instead, they are borrowed from their material cycle for a certain period of time and later returned there at equal value and utility. Sourced from recycled materials, the prototypology is a built example of urban mining; designed for disassembly at the end of its service time, it also represents a material banks for future projects - while proofing the claim, that it is possible already today to build within a circular system.
