A six-storey commercial office building designed and certified as a Living Building, meaning it produces all its own energy from rooftop solar, collects and treats all rainwater on-site, and uses no Red List toxic materials. It is frequently cited as the greenest commercial building in the world.

Innovation highlights

• net-zero energy via 575 rooftop solar panels generating 100% of building electricity
• composting toilets and rainwater harvesting meeting 100% of water demand
• full Living Building Challenge certification — one of few commercial buildings globally
• 242-year design life with fully documented material transparency
• operable windows only — no mechanical cooling despite Seattle climate
