The Passive House movement (Passivhaus) started in Germany 15 years ago and recently spread to the United States. It is a group of builders, architects, engineers, manufacturers and others focused on reducing the energy use of buildings, large and small, including houses. They’ve developed a rigorous standard that results in a building using up to 90% less energy for heating and cooling. Over 20,000 buildings in Europe have been certified to meet this standard. So far only a handful of homes in the U.S. have been certified, but many new projects, aimed at meeting the standard, where presented in Urbana. And by the end of 2009, there will be over 200 people in this country certified as Passive House Consultants, so the movement should continue to grow exponentially.
