Passive House: The Idea of the Airtight Home Takes Hold Among Green-Building Experts. By Ruth Mullen, The Oregonian, February 4, 2009. "The 'super-insulated' house got its start in Canada in 1977. The Germans followed up in 1991 with an improved version by eliminating the furnace altogether. They called it a 'passive house,' which quickly caught on in their chilly climate. This revolutionary concept has only recently spread to the United States, where it is gaining devoted followers among green building enthusiasts... The key to indoor comfort in passive homes is a central ventilation system that is widely used in Europe but still relatively unknown in the United States. As warm, stagnant air is expelled through the heat recovery ventilator, it passes by incoming streams of fresh, cooler air, allowing the heat to transfer without mixing the two streams of air." No Furnaces but Heat Aplenty in 'Passive Houses'. NYTimes, December 26, 2008.
