Symposium sustain.build.repeat. - 3. Symposium on Sustainable Construction 2022 (Podcast)
The symposium sustain.build.repeat. is dedicated to the resource of the 21st century: our building stock. With growing waste volumes and ever scarcer raw materials, careless building demolitions and replacements must be avoided. Instead, existing buildings should be converted and rebuilt, components removed, reused and reused again. The linear system geared towards the demolition of buildings corresponds neither to an economic nor to an ecological handling of the resources at our disposal. The grey energy stored in the materials used, in transport and in construction, as well as the cultural and social value of architecture are lost. It is therefore important to think in cycles and to preserve as much of the existing building stock as possible on the premise of resource- and climate-friendly architecture: on the one hand as a changeable space in which various usage scenarios are possible, and on the other hand as a material depot, secondary raw material supplier and building material store. The material, economic and social value of the building stock can be preserved through the cycle-compatible conversion and recurring transformation of the building stock. The creative re-use, re-utilisation and co-utilisation of existing spaces of opportunity creates new social and architectural challenges. Thus, the spatial complexity, the appropriation of architecture by society and its adaptability to future needs can become unique design tools. In this symposium, representatives from science and industry, research and practice will present ideas, strategies and impulses on how the ecological necessity of reconstruction and transformation of the existing can become an enriching element of a caring, needs-oriented and value-preserving architecture in ecological balance. It offers the opportunity for joint discussion and exchange on the significance and value of the existing for the architecture of today and tomorrow.
