"Green Building is energy conservation in new clothes. If you look at the environmental impact of all the stuff in the green building program, the impact of energy conservation is huge.  Compared to that the impact of the materials you choose is small."

-Steve Loken, Keynote Speaker,

Seattle Washington,  March 2005
