Bullitt Center

The Bullitt Center, located at the intersection of the Central District and Capitol Hill in Seattle, is recognized as the greenest commercial building in the world. Officially opened on Earth Day in 2013, this six-story structure was designed by the Bullitt Foundation to achieve a 250-year lifespan and is certified as a 'Living Building.' It features a large solar panel array that produces more energy than it consumes, a rainwater collection system, and composting toilets. The building's innovative design includes geothermal wells for heating and cooling, and it promotes sustainable transportation with no parking spaces, only bike racks. Visitors can explore its cutting-edge ecological features and enjoy views from the prominent staircase that encourages stair use over elevators.
