ZGF designed Port of Portland headquarters aims for LEED Gold
The Port of Portland’s commitment to sustainable practices is showcased in its new Headquarters Building and Parking Garage 2 (HQP2), designed by ZGF Architects. Sustainable design was a critical driver, with LEED Gold Certification serving as a project goal. In addition, the building allows the Port to consolidate its workforce into one building, save operational costs and increase parking capacity at the Portland International Airport.
The new 205,000 GSF building consists of three floors of office space atop seven floors of parking. ZGF worked closely with the Port to develop new standards for an open office space plan in an effort to increase collaboration and foster a team environment. Cost-effective solutions were a primary concern, as well as telling the Port of Portland story through environmental graphics and artwork.
The metal and glass exterior of the building relates to the palate of materials used throughout the rest of the airport, as well as to materials common to aviation and marine vessels. The exterior of the new parking structure not covered by curtain wall is screened by vertical pieces of channel glass, maximising daylighting of the garage while unifying the office building and parking garage with glass elements that will glow with light at night.
The office floors make use of high-performance glazing on the north and south sides with appropriate external shading on the south to maximise daylighting and views for all the work spaces. Solar control on the south is provided by automatically controlled perforated horizontal blinds. The building also features a green roof, ground source and active radiant ceiling panel heating and cooling, an organic wastewater treatment system, water-efficient fixtures, low-VOC paints and materials, recycled content and regionally manufactured materials. The combined effect of the multitude of sustainable building practices and operations translates into a CO2 savings of 868 Metric Tons per year.
