Today I met with Adam Dadeby and had the opportunity to look over a Passivhaus in Dartington. Passivhaus originated in Germany in 1991 but now countries around the world are adopting the standard and adapting it to their local architecture and climate. Since 2009, it has been taking off rapidly in the UK too. A Passivhaus with ultra low energy building standard needs 90% less energy than a typical UK home, protecting owners or tenants from fuel poverty for ever. Designed and built with proper care and attention to detail, they stay very comfortable in summer and winter, without relying on lots of complex technology. A very interesting project.
