Sustainable Sustainability: Vedvarende Holdbarhed

The results of the Research Project (Vedvarende Holdbarhed), carried out in 2015 – 2018, by Søren Vadstrup, but still continuing, has shown, that buildings built before approx. 1960 – must be maintained and renovated with completely different materials than buildings built after approx. 1960. Namely the classic building materials, building constructions and craft methods. In this way, they can achieve a (largely) unlimited and continuous durability and lifespan – called sustainable sustainability (Vedvarende Holdbarhed).
