The 'Footprint at the Bridge' building in Seattle is noteworthy for a number of reasons, but most important is its rain-catching strategy. Each year, the entire structure uses over 100,000 gallons less water than a standard-code building of commensurate size.
The residents of 'Footprint at the Bridge' accomplish this amazing feat by collecting rainwater from the rooftop and from courtyard areas. This water is then deposited in a large holding cistern underneath the building and then used as needed. In addition to the 'Footprint at the Bridge' building's various other eco-friendly design features, this system has put the structure up for candidacy as an LEED Platinum status recipient -- one of the highest honors eco-friendly institutions can achieve.
