Bullitt Center & the Living Building Challenge

The Bullitt Center is a 6-story, 50,000 sq. ft. office building being constructed in downtown Seattle. When complete project owners say it "will be the greenest, most energy efficient commercial building in the world." The two case studies featured here highlight some of the elements which are helping them meet this goal.

The Bullitt Center will be the greenest most energy efficient office building in the world

The Bullitt Center is a 6-story, 50,000 sq. ft. office building being constructed in downtown Seattle.  When complete project owners say it "will be the greenest, most energy efficient commercial building in the world."  To meet this ambitious goal, they embraced the Living Building Challenge, the worlds most strenuous benchmark for sustainability.  This meant the building had to be "net-zero" energy and "net-zero" water, so it was designed with a solar array that will generate as much electricity as the building uses and rainwater harvesting system which will supply as much water as the building needs, with all wastewater treated onsite.  The two case studies featured here highlight some of the elements which are helping them meet this benchmark, and which also posed the most significant permitting challenges in order to be approved.  Fortunately, Seattle recently passed a Living Building Challenge Ordinance, which helped clear some hurdles.  Read the case studies to learn how!
