Twelve west, High-rise building in downtown Portland, Oregon, United States
The 22-story Twelve West combines retail spaces on ground level, office areas from second to fifth floors, and residential units in upper levels.
The construction of this $137 million structure started in 2007 and concluded in 2009, after modifications to initial plans that included a hotel.
The building connects multiple Portland districts, serving as a central point between the Pearl District and downtown business areas through retail and pedestrian links.
The structure incorporates rainwater recovery systems for office facilities and fire protection, while solar thermal panels supply 24 percent of water heating needs.
Four 45-foot wind turbines installed on the rooftop generate 5,500 kilowatt hours annually, contributing to the building's power requirements.
