Scheduled Activities

Morning: Lectures & Discussion / Afternoon: Visit to Binckhorst in den Haag

Day 1 is dedicated to getting to know Binckhorst. The area will provide the canvas for our reasoning about scales as it aspires to become an exemplary circular redevelopment for South Holland with mixed residential and industrial commercial uses. But how does the increasing need for more housing affect planning in terms of circularity? Our guests on that day will introduce participants to the notion of circularity and will discuss what its current limitations are. An organized visit to Binckhorst will take place in the afternoon after the lunch break. 

Morning: Lectures & Discussion/ Afternoon: Workshop

CBE Hub research considers circularity to cross all scales: from materials; to components and to buildings and from neighborhoods; to cities and to regions and situated in the entanglement of each scale with the six aspects of technology, management, design, economy, resource flows and the dynamic relations of all stakeholders involved. DAY 2 sessions aspire to steer attention to the interdependence of scales. A number of selected guests will discuss all scales from materials all the way to regions. During the afternoon workshop, participants will contextualize this input specifically for Binckhorst .  

Morning: Lectures & Discussion/ Afternoon: Workshop 

Day 3 is dedicated to examining models of cooperation within the circular built environment. How does the systemic character of circularity manifest amongst stakeholders? Can there be new types of collaboration and what are the requirements for such collaborations to succeed? Our guest lecturers will showcase examples of synergistic alliances at neighborhood and at city scale. A second workshop will follow in the afternoon: participants will engage in identifying circular scenarios for the future development of Binckhorst.
