Twelve | West: Portland, OR

Urban Connections



Timothy Hursley

How do you foster vitality and development in an emerging urban neighborhood? The developers of Twelve | West, located in the West End area of Portland, Ore., sought to accomplish these goals with a sustainably focused mixed-use high-rise that offers shopping, dining, office space and apartments in one location. Major contributors to the project's sustainability include extensive daylighting, efficient underfloor air ventilation with perimeter baseboard heating and passive chilled beams, natural ventilation via operable windows and rainwater reuse. The double LEED Platinum building, which opened in 2009, recorded an annual energy use intensity of 44.9 kBtu/ft2 during its first year of operation.
