Passivhaus is a design methodology for ultra low-energy buildings, promoted by the Passivhaus Institut in Darmstadt, Germany. There are about 12,500 Passivhaus buildings worldwide, the vast majority of them in Germany and Austria, and the approach is rapidly growing in popularity in the UK as developers and designers consider their options to meet the Government's zero carbon targets.
On this site you can follow the story of the project via our blog and through our photo record. Also, you can find out more about the organisations involved and the technical issues involved. For more information on Passivhaus please visit:
