A net-zero building with passive heat recovery, waterless and composting toilets, automated external blinds, bike rack and repair station, smart controls, and an elevator that converts kinetic energy into electricity? It sounds too good to be true—but it's not. Seattle's Bullitt Center, designed by architecture firm Miller Hull and completed in 2013, is proof that self-sustaining, net positive buildings are a realistic option and can be financially achievable, comfortable for tenants and a beautiful addition to the community with essentially no environmental footprint.

Join us for a discussion with Miller Hull's Margaret Sprug about the Center—certified as the world’s largest commercial Living Building in 2015 and one of the most energy efficient commercial buildings in the world—including its potentially game-changing "Negawatt" energy investment system, designed to allow energy efficiency to be bought and sold as an investment, separating the efficiency investor from the building owner.
