In his doctoral dissertation, Mario Kolkwitz studied how construction and demolition have transformed the building stocks of Tampere and Vantaa between 2000 and 2018, and how these changes affect urban form and material flows. This work shows how urban development strategies—such as greenfield development in Vantaa and replacement-oriented growth in Tampere—create distinct patterns in the cities’ building and material stock profiles. These insights are crucial for designing circular economy strategies and resource-conscious urban planning, helping cities reduce environmental impacts and adapt to future needs. The findings benefit urban planners, policymakers, and the construction sector to make cities more sustainable and resilient.
The doctoral dissertation of MSc (architecture) Mario Kolkwitz in the field of urban sustainability and circular economy titled Cities of Flows - How construction and demolition shape building stocks, urban form, and material flows will be publicly examined at the Faculty of Built Environment at Tampere University on 16 January 2026.
The Opponent will be Associate professor Tomer Fishman from the Leiden University, Netherlands. The Custos will be Professor Satu Huuhka from the Faculty of Built Environment at Tampere University.
