Twelve West (stylized as twelve | west) is a 22-floor, mixed-use apartment and office building located in downtown Portland, Oregon, United States. The building is home to INDIGO @ twelve | west apartments and ZGF Architects LLP. During design and construction the building was known as “12W” and “ZGF Tower”,[1][2] but the name changed after a naming contest in July 2009.[3] Initial plans included a hotel and a total of 31 floors, but they were revised after the hotel company withdrew.[2]

Wind turbines

Four 45-foot-tall (14m) wind turbines are mounted on the roof for the purpose of research and generating electricity.[4] The turbines were expected to generate 9,000 kilowatt hours yearly and provide data on wind flows[5] and bird-strikes.[6] However, a study from the NREL indicated that the turbines are less productive; the system "generates approximately 5,500 kilowatt-hours (kWh)/year."[7]

Tenants

There are three distinct uses for twelve | west in separate parts of the building. Ground floor provides retail space, a building lobby, and garage access. Floors 2–5 are offices, currently the headquarters of ZGF Architects LLP, the architect of the building.[1]
