« While building with reused components has become one of the most widely noted phenomena in the European architectural discourse in recent years, it is only slowly finding its way into the everyday practice of architects. Whenever components that can last for decades are not destroyed but reused for new buildings, this not only saves resources. It also drastically reduces energy consumption and greenhouse gas emissions during the construction phase. Circular construction brings with it a whole range of questions, howeverranging from technical and energy-related to legal ones. This applies even more so today, although the practice itself can look back on a long tradition across history. This book is a comprehensive compendium on the topic of reuse in construction that, in addition to the theoretical discourse, also looks at the various practical questions by using a concrete example: the head-end building K.118 on the Sulzer Areal in Winterthur, which is the largest building in Switzerland built primarily with reused components to date. Since 2018, an interdisciplinary research project has evaluated this pilot project with regard to the architectural-constructive, energy-related, economic, procedural and legal aspects involved in its construction. The texts and graphic materials collected in this book present the findings of this study in a highly informative and visually striking way. »--Page 4 de la couverture.
