The document announces the International Passive House Days from November 9-11, 2012. During this event, residents of Passive House buildings around the world will open their homes to demonstrate the comfort and energy efficiency of the Passive House standard. Passive House buildings require just one tenth the heating energy of a conventional building while providing a comfortable, draft-free indoor environment with even temperatures year round. The Passive House Days will give potential builders and owners a chance to directly learn about the standard from owners and architects and experience the comfortable ambience of Passive House buildings firsthand.
