Living Building Challenge

One of the most ambitious aspects of the Bullitt Center will be achieving the goals of the Living Building Challenge (version 2.0), as described by the International Living Building Institute.

To be certified as a Living Building, a structure is required to be self-sufficient for energy and water for at least 12 continuous months and to meet rigorous standards for green materials and for the quality of its indoor environment.

The Living Building Challenge requires a project to meet 20 specific imperatives within seven performance areas (or “Petals”). For the Bullitt Center, meeting the imperatives will include the following:

• Site: The location will support a pedestrian-, bicycle-, and transit-friendly lifestyle.

• Water: Rainwater will be collected on the roof, stored in an underground cistern and used throughout the building.

• Energy: A solar array will generate as much electricity as the building uses.

• Health: The building will promote health for its occupants, with inviting stairways, operable windows and features to promote walking and resource sharing.

• Materials: The building will not contain any “Red List” hazardous materials, including PVC, cadmium, lead, mercury and hormone-mimicking substances, all of which are commonly found in building components.

• Equity: Unlike many office buildings, large operable windows will offer fresh air and daylight to all the people who work in the Bullitt Center. The goals of Seattle’s Community High Road Agreement will guide selection of the construction team.

• Beauty: Stunning architecture, an innovative photovoltaic array, a green roof and other native plantings, large structural timbers and a revitalized neighboring pocket park will help beautify the surrounding streetscape.
