The Bullitt Center opened its doors to the public for the first time after a ceremony that included speeches by government and community leaders.

Its innovative use of rainwater for most of its water needs, a solar roof that produces more energy than the building consumes and all kinds of other technological breakthroughs have many calling it the greenest building on earth.

Bullitt Foundation CEO Denis Hayes was honored for his involvement in this project and a lifetime of environmental activism.

Seattle Mayor Mike McGinn proclaimed Earth Day 3013 as Denis Hayes day. Hayes helped create the first Earth Day in 1970.

The building has already spawned new technology from companies trying to produce building products to meet its rigid standards; no toxic materials anywhere on the campus.
