Buildings consume 40 percent of the world’s resources. Furthermore, 50 percent of the energy in this country goes directly or indirectly into buildings.

The construction of a typical home in this country consumes about an acre of clear cut forest and generates roughly four pounds of waste per square foot. Changing the way we build has become a priority.
