Rising 23 stories above the intersection of Twelfth and Washington streets in Southwest Portland, Oregon, Twelve|West is a mixed-use building designed with sustainability and ongoing learning as integral goals. It is one of the first urban office buildings to feature four building-integrated wind turbines that are predicted to generate roughly 10,000 kWh per year, enough to power the elevators. The building includes street-level retail space, four floors of office space leased to a national architectural firm, 17 floors of apartments, and five levels of below-grade parking along with three roof-level terraces and gardens.
