GBP report on the launch of a new website for PassivHaus in the UK. Features which make a house a PassivHaus include:

Super-insulation: opaque fabric U-values must be less than 0.15 W/m2K, with U-values for windows and doors generally needing to be less than 0.8 W/m2K (for both the frame and glazing). Thermal bridges are also eliminated. Airtightness: 1 m3/(h.m2) at 50 Pa test pressure or less Whole house mechanical ventilation with heat recovery (75% efficient or better).

This exceeds current building regulations (2006 Part L1A) and the site cites that 4000 examples have been built.
