Vestas Headquarters in North America

Tetra Tech’s High Performance Buildings Group provided mechanical, electrical, and plumbing design, as well as lighting, fire alarm, telecom, and security systems design for Vestas—one of the world’s largest manufacturers of wind turbines.

The manufacturer decided to move its North American headquarters into the historic Meier & Frank Delivery Depot in Portland, Oregon. They were challenged with sustainably modernizing a building that has stood for nearly a century and is listed on the National Register of Historic Places.

The result was a LEED Platinum designation, an Energy Star score of 99, and the International Living Future Institute’s (ILFI) energy efficiency REVEAL label, making this historic Portland landmark the most energy-efficient building on record in 2014, in the United States.

Tetra Tech also provided energy modeling services, computational fluid dynamics (CFD) analysis, LEED scoping, and sustainable planning sessions, including recommendations on sustainable design elements. A rainwater harvesting system was implemented to decrease water usage and waste. A central, multi-story atrium was constructed to reduce energy use by providing much of the interior with strong natural lighting. The building now also features the largest roof-mounted solar energy area in the city’s central business district.

With five floors of work space for some 400 employees and built-in flexibility to accommodate up to 200 more for future expansion, this is a place that Vestas, its employees, and co-tenants can call home for years to come.

With maintaining the building’s early-20th century look and feel as a critical goal, the new Vestas Americas headquarters stands out as an example of the real success in redeveloping and repurposing historic structures.
