Symposium CIRCULAR STRATEGIES - Towards a sustainable built ennvironment

The climate crisis and scarcity of resources are forcing us to reduce the ecological footprint of architecture and urban development, but this obligation also opens up new opportunities for cultural expression. The principles of circular economy play an important role in approaches to sustainable architecture. The symposium will address this topic on different scales - from building components to the urban fabric - and under two aspects: How can existing materials, buildings and urban areas be adapted and reused, and how can components, architectural objects and cities be designed for future reuse and transformation? International experts from architecture and social ecology will present various concepts and discuss them with the audience.
