Heating energy consumption is about 1/10 of conventional in Germany, and holds true for similar US climates. Total consumption for all household uses is harder to quantify, and depends quite a bit on things that are out of the designer's hands, such as appliances and electronics. But I think the most essential point about the energy performance of Passive House is that it makes 100% renewable energy practical and cost-effective. Thanks for the post!</p> Wed, 07 Jan 2009 18:50:18 -0500 David White 1130239 at http://www.fastcompany.com
