A New York Times December 26 2008 article No Furnaces but Heat Aplenty in ‘Passive Houses’ gives some welcome attention to this otherwise overlooked concept. While the article suffers from a poor description of how the heat exchanger functions and makes no mention of the existence of the smaller North American-style heat recovery ventilators, it does end with a great quote about keeping the house size to 500 square feet of floor area per person. Ultimately size is the key to sustainable housing.
