Key results

Key lessons learned

1. We documented the collaboration and decision-making process during real construction projects with circular ambitions, capturing one case in detail. In doing so, we showed the importance of a cross-point figure between construction team and expert team. 
2. We have already drawn up diagrams and concepts of possible new chain collaborations within the construction sector based on practical experience. 
3. Within the supervised construction projects, we were able to identify a measurable improvement in environmental impact and reuse potential. 
4. We conducted a concrete cost-benefit analysis of the co-creation process, comparing the financial cost with the environmental benefits.

1. To vitalise the collaborative process and research around circular construction and avoid watered-down discussions, we need to take the conversations out of theory, and organise them around concrete practical cases. 
2. It is possible to significantly reduce the environmental impact of a construction project, but it takes time and knowledge. In the pilot project, we found that a 50% improvement o.w. environmental impact costs around €20,000. This is a rough estimate, but gives an idea of the possibilities and challenges. 
3. There is little learning space in the field and building issues are becoming increasingly complex. Architectural offices are overloaded and other stakeholders also have little time to learn or adjust. To avoid clogging up the system, a new, more social and open revenue model seems indispensable. 
4. Extensive preparation of a project application pays off in the long run. It is important to take sufficient time to write out a project proposal. Time should also be made for reflection and adjustment throughout the process.
