Circularity strategies and best practices

This WG will work on developing innovative methods to apply circularity strategies in design and construction activities and identify best practices.

Furthermore, this WG aims to create integrated design and engineering solutions for dynamic and circular buildings which by design provide an answer to circularity challenges of resource efficiency and waste prevention through embedding concepts of DfA, DfD, DfC and reversibility among others for new and existing buildings.

  • T1.1. Review and analysis of state-of-the-art;
  • T1.2. Identification of existing applications of circularity strategies and circular materials for both new and existing buildings as well as the national and regional level of relevant regulations and governmental support and action plans in COST partner countries;
  • T1.3. Identification of technical barriers for the uptake of circular strategies application by analysing building configurations and interdependences between systems, components and layers, considering local specifics (architecture and construction techniques). Also, review of the methods dealing with the allocation of environmental burdens or benefits in the case of reuse of building components;
  • T1.4. Development of an e-learning section within the Action’s website for circular application by mapping existing concepts, strategies, best practices, case studies, projects and success stories worldwide (a joint task with WG4);
  • T1.5. Development of novel design strategies and solutions that enable the implementation and evaluation of circularity principles (close, slow and narrow the loop) and concepts throughout the whole lifecycle of a building, including design for disassembly, reversibility, adaptability, reconfiguration and spatial transformability;
  • T1.6. Development of guidelines for the initial design phase to steer the thinking towards circularity implementation since the project conceptual stages;
  • T1.7. Development of adapted strategies and concepts for circular re-design of existing buildings aiming at prolonging their functionality and usability and therefore increasing their circularity;
  • T1.8. Development of simulation models through BIM with circularity options to predict future scenarios and identify potential trade-off possibilities;
  • T1.9. Assessing the environmental benefits of different circularity strategies using LCA tools for several scenarios and identifying best practices based on the lowest potential environmental impact.
