DGNB Discourse
"Built Positive: Together We Build What Is Next"

24 April 2017
DGNB Office, Stuttgart

Circular economy has the potential to become one of the guiding principles for the construction and real estate sectors. The DGNB Discourse event introduces into the concept of circular economy and kicks-off the Built Positive initiative in Germany which aims to enhance the value and quality of materials and products used in the built environment and in the circular economy. During the event selected best practice presentations highlight the various opportunities to create value.

About Built Positive:

Built Positive is a co-creative movement to increase the built environment's positive impact on people, planet, and economy by designing materials for circularity, innovating to improve these inputs, and quantifying their positive impact from the molecule through to the metropolis. Built Positive ensures that materials sustain their value and buildings become material banks that yield future value for their owners. Human health and productivity of occupants is improved through verified inputs with optimized chemistry. Sourcing and re-sourcing impacts are enhanced through better design and optimized for beneficial reuse.

Built Positive has been initiated by the Cradle to Cradle Products Innovation Institute.
DGNB is the official partner of the initiative in Germany.

Michel Weijers

                                             Michel Weijers is an urban planner by origin (Radboud university Nijmegen). After completing his study, he has continuously been active in the field of urban (physical) planning. He worked for the municipality of Helmond, the development-oriented Rotterdam and the municipality of Venlo. In these projects and jobs, he has worked in various roles: first he was an economic/urban planner and he subsequently worked as a project manager in urban planning projects.
In recent years, as a result of his own convictions and the C2C-orientedness of the municipality of Venlo, the focus has increasingly been shifted towards applying the C2C principles in urban and area development. As of 2015, he is working as a Managing director at the C2C ExpoLAB in Venlo for 3 days a week. The remaining 2 days he is still a project manager for the C2C-inspired city hall that is currently still under construction.
It is his personal belief that the C2C principle is the ideal means to truly add value to buildings and areas in urban planning and building projects. That will not just happen by itself, but especially by also providing insight in the economic benefits of investing in sustainability, a circular economy and C2C, more and more stakeholders will open up to new approaches to development projects. As a knowledge centre in the field of C2C, the C2C ExpoLAB, in combination with the actual work, is the ideal tool for this: it will connect theory with practice. This way, we can both literally and figuratively build on a positive future together, in a way that is also economically feasible.
