The Passivhaus standard is probably the most stringent available standard for energy-efficient buildings. Passivhaus buildings have to meet a strict airtightness standard (0.6 air changes per hour at 50 Pascals), so they tend to be much tighter than homes that meet Energy Star or LEED for Homes requirements.
The standard was devised in the 1990s by Dr. Wolfgang Feist, a German physicist inspired by superinsulated houses built in Canada and the U.S. during the late 1970s. Thousands of superinsulated buildings in many countries — including a few dozen in the U.S. and Canada — have been certified as meeting the Passivhaus standard.
