May 3, marked the first official day for Port of Portland staff from the downtown office headquarters and the airport terminal to consolidate into offices on three floors atop the new parking garage at Portland International Airport.

A showcase for sustainable practices, the building incorporates many state-of-the-art green technologies; its Leadership in Energy and Environmental Design, or LEED, gold rating is pending. Visitors to the new building’s lobby will see what looks like a large indoor garden but which is, in fact, a functioning indoor wetland. Called a Living Machine® system, it treats wastewater for reuse in the building’s toilets and cooling tower.

Underneath the building, more than 200 pipes provide ground source heating and cooling in a closed loop system, serving the passive radiant ceiling panel heating and cooling inside. Features like a 10,000 square-foot eco-roof, daylighting, window glazing, fixed exterior shading and water-efficient fixtures help save energy, water and money. Many items from the former building – furniture, art, equipment – were refurbished and used in the new headquarters. All combined, the building will use 75 percent less water and 36 percent less energy compared to a standard building of this size. Construction of the building was also a generator of jobs for minority-owned and small, local businesses.
