How to design a circular building? - Hans Hammink

“Constructing with circular materials is not only good for the planet, but also helps to make the architecture more interesting.” says Hans Hammink, architect and associate at de Architekten Cie. and my today podcast guest. Hans Hammink is an expert in integration the circularity in the architectural process. He was involved in the projects such as CIRCL Pavilion (Amsterdam Zuid), Edge Olympic, bicycle parking facility in Eindhoven, EDGE Amsterdam West. He is also one of the creators of the Building Passport: a digital twin of a building, a 3D model linked to circular data. Hans is also a teacher at the Academy of Architecture in Amsterdam. In 2021 he published a book: Lessons In Circularity. Construction industry consumes around 60% of the world’s materials. It is responsible for around 53% of the world’s greenhouse gas emissions, a big part of which is attributed to buildings. The building sector must limit the energy consumption, stop using sources of fossil fuels, limit the CO2 footprint and stop over-exploitation of raw materials. How? The construction industry should shift towards the circular economy. By closing cycles and reusing materials, we could tremendously limit the waste in the building sector and be more responsible about the climatic consequences. What does circularity in architecture mean? What are the design guidelines for a circular design? Is it possible to design a 100% circular building? Is there a lot of greenwashing regarding circular design? How do you balance aesthetic and functional considerations with circular design principles? How do you address the resistance or scepticism from the clients or stakeholders when proposing a circular design? Can circularity fit the business model?
