industry Slow Motion San Francisco—In order to accommodate a 22 percent growth in passenger traffic and the additional of several new air carriers, Gensler is set for a major expansion and renovation of San Francisco International Airport’s old international terminal. The rebuild will have a Slow Food© focus. Slow Food is a non-profit organization founded to counteract fast food and its effects on daily quality of life. rendering courtesy of Gensler The 587,000-sq.-ft., $383-million terminal will also feature exhibits by local and world-renowned artists, and it will be designed as an extension of the Bay Area’s culture and aesthetic. It will also have a strong emphasis on comfort and service, with the addition of a post-security re-composure zone, a “meeters-and-greeters” lounge, and hotelinspired seating areas. The new terminal is aiming for LEED silver certification and will support the airport’s goals of zero waste and a reduced carbon footprint. All the sustainable elements will reduce the facility’s greenhouse gas emissions by an estimated 1,667 tons per year. A substantial portion of the infrastructure from the existing building will also be used in the renovation, reducing the impact of the new terminal by a one-time amount of about 12,300 tons of carbon dioxide emissions. The original building will be stripped down to its structural steel skeleton and receive a new metal and glass building envelope, promoting an abundant use of natural light. It will also become a teaching tool, as signage will engage travelers and educate visitors on the terminal’s sustainable features. The new terminal is expected to be completed by fall 2011. Ahead of the Game directions. They then built a large-scale physical model of the building to test it. The Southwest Windpower horizontal axis turbines are 12 ft. in diameter and feature a passive yaw or rotation system that orients the turbine blades to the wind, and the downwind blade design eliminates the need for a tail or other orienting device. The turbine array is predicted to generate about 10,000 kwh per year. Local and state agencies funded the entire system’s cost through renewable energy grants. Other sustainable features include a 6,000-sq.-ft. terrace and “eco-roof,” which serves to mitigate stormwater and reduce the building’s heat island effect. Office ventilation is mostly achieved through a combination of an Underfloor Air Distribution System (UFAD) and natural ventilation. The system provides individual control through adjustable diffusers at each workstation. Passive chilled beams will aid in cooling on particularly hot days. Passive chilled beams are perforated metal panels mounted near the ceiling and chilled with cold water tubing. Twelve West is on track to achieve LEED-NC Platinum and LEED-CI Platinum for the ZGF offices. photo courtesy of ZGF Architects Portland —Twelve West—a new mixed-use building designed by Zimmer Gunsul Frasca and housing the design firm’s Portland offices on four floors with street-level retail and 17 floors of residential space—can also boast the first U.S. installation of a wind turbine array on a high-rise. The four turbines are 270 ft. above ground, which places them well above the major turbulence caused by the irregularities in the built environment below. An extensive body of research went into their placement and development, as the design team took into account urban topography, weather data, and seasonable variability of wind contract october 2009 www.contractmagazine.com http://www.contractmagazine.com
