The Greenest Office Building in the World

A look at the innovations inside the Bullitt Center, a new office building in Seattle that produces its own water and electricity. The Bullitt Center, a 50,000-square-foot Seattle office space that opened in April, can generate its own water and electricity. Because of this and the building's other innovative features--sustainable materials, energy-efficient technology, and composting toilets--it has been dubbed the world's greenest office building. It took 16 months to construct the $30 million building, which was funded by the Bullitt Foundation, a local environmental organization. But the idea has been in the works since 2008.
