A passive house takes an active stand for the environment


The heating and cooling of homes accounts for some of the greatest energy consumption in the United States, and contributes significantly to the release of CO2 into the atmosphere. A movement of "passive housing" is cropping up in response - the building of small, low-impact houses that are energy efficient and eco-conscious. One in Boulder, CO - built by an amateur architect - has received international certification and may serve as a model for future housing construction.
