    The Dresden Nexus Conference (DNC) is an international conference series dedicated to advancing research and the implementation of a Nexus Approach to resource management.

    With the topic “Circular Value Creation for Building Stocks – Towards a Pioneering Role for Dresden and Saxony”, this interim workshop (DNCi2021) is designed to extend the DNC2020 theme “Circular Economy in a Sustainable Society” and move it to the local level.

    The workshop aims to exchange new research findings and support a discussion on strategies for action. Organised by UNU-FLORES, Technische Universität Dresden and IOER, the organisers conduct panel discussions with pointed presentations and forward-looking discussions. The format is a ‘pressure cooker’: contributions are short, prepared together and based on shared goals and key questions.

    During the panel discussions “Systems thinking and technical innovations for decarbonisation and circular building” (Panel I) and “Relevant information and modelling of building stocks to support a circular construction industry” (Panel II) representatives from academia, politics and industry stakeholders discuss questions about the transformation of building stock.

    This is an invitation-only workshop conducted in German.


    The building stock is facing a transformation: Buildings should meet the requirements of climate and environmental protection and resource conservation; at the same time, they should be socially affordable and offer investment incentives. Therefore, fundamental questions arise: What new opportunities emerge against the background of current social discussions on resource and climate protection from technical innovations and their systemic merging to decisively improve circular value creation in existing buildings? Which tools and information are required to achieve circular value creation in the building stock, and how can the transition to business models succeed? Which innovation alliances between companies, politics and research can be forged in Dresden and Saxony, and how can existing initiatives be bundled?

    The topic of circular value creation in existing buildings is an interdisciplinary research direction with increasing relevance. According to estimates by the International Resource Council (UNEP IRP), at least 80% of building-related life-cycle greenhouse gas emissions can be reduced by 2050 if better design and reusability of building materials and resource-efficient building renovation are favoured. At the same time, this serves to avoid waste and conserve raw materials. The key questions for research, housing industry and policy are shifting from solar installation and new passive houses to systematic thinking in existing buildings and circular value creation. Which new building materials offer advantages in the development of existing buildings? Which holistic and life-cycle approaches exist for building renovations? Which tools can research use for action strategies?
