This talk explores the Passivhaus Standard's potential to shape the low-carbon, energy-efficient and healthy buildings practices and policy agenda. We explore Passivhaus's positive contribution and negative implications for implementing the United Nations (UN) Sustainable Development Goals (SDGs). The discussions examine the Passivhaus principles and how it responds to SDGs responding to the UN's specific targets and indicators. The second sets the context for building Passivhaus using natural materials, particularly bio-based fibre materials building upon the response to the SDGs discussing these new approaches.
