I blog about all things eco-architecture, from materials and structure to philosophy and design, with a focus on the Passivhaus standard. Passivhaus offers clearly defined energy and comfort standards that produce excellent results. The technical criteria result in buildings that are healthy for both the people and the planet. The principles of Passivhaus are: build robustly, wrap it up warm, use the sun for heating and maintain good air quality. These simple criteria make the standard a sustainable solution for everyone - which is why Passivhaus is core to the ethos of my practice and the focus of my research.
