Dr. Stephan Brenneisen: Living Roofs - Biodiversity and Water Retention by Design Measures

Dr. Stephan Brenneisen from the Zurich University of Applied Sciences has been researching urban biodiversity and roofs for over 25 years. In a video presentation, he talks about his findings. We asked him specifically to speak about what to keep in mind when designing biodiverse roofs. What can landscape architects learn from his extensive experience, how to design performative and biodiverse roofs in a simple and more nature-based way?
