Positions on Circularity in the Built Environment

March 13 – 16, 2017.  Circularity concerns different scale levels of scale such as urban design, architecture, building technology and building management. Legal, economic, and data management as well as construction issues are of major importance. We observe a strong trend to approach circularity within Europe, while, at the same time, the field is still largely uncharted. The event brought together key expertise across the BauHow5 architecture faculties, TU Delft, UCL Bartlett, Chalmers, TU Munich and ETH Zürich, aiming at answering the following questions: Who is working in the area? Is there a common understanding about circularity? What are the national and international funding possibilities, and how can the cooperation of the BauHow5 universities be stimulated? A three-day program was designed. The first day was open to the public and featured position lectures of professors of BauHow5. Room was given for interaction with the visitors. On the second day, 16 doctoral candidates presented their work, and the event was concluded with a group working session on day three. Here an approach was made to come to a common definition of Circularity in the Built Environment and further steps for cooperation were defined.
