PRESS RELEASE – GRAND FORKS, ND – October 29, 2013
The U.S. Green Building Council (USGBC) has awarded LEED Silver certification to the Byron L. Dorgan Terminal at the Grand Forks International Airport. Designed by JLG Architects, it is one of only five international airport terminals in the United States to achieve LEED certification, and one of the first in the Midwest. As such, the Grand Forks Byron L. Dorgan Terminal will become a featured case study on the Department of Energy’s website.
Even more impressively, the building is out-performing its own projections. Designed to lower energy use by 14.2% compared to other relative buildings, energy was actually reduced by 15.7%, or $14,000 a year. This was primarily made possible through the installation of a geothermal system – the most energy-efficient, environmentally clean, and cost-effective system for temperature control – which was installed under the parking lot and uses the Earth’s constant temperatures to heat and cool. Inside, a Building Management System monitors and adjusts space temperatures, and the ground floor lobby uses floor heat to keep the space warm from the ground up.
Water use at the Terminal was decreased by 43.1%, or 83,061 gallons a year, which is the equivalent of the usage by 213 homes a day for a family of four. The sinks save a gallon of water per minute, urinals save just under one gallon per minute, and the lavatories save two gallons per minute. Additionally, the landscaping includes native and adaptive plantings that rely on standard rainfall and require no permanent irrigation.
Additionally, studies have shown that superior air quality and comfortable thermal conditions can have a 41% improvement on health and a 15% increase on productivity. At the Terminal, humidity is controlled by two dedicated outdoor air systems that deliver fresh air, and temperatures are regulated to stay between 68-72 degrees for all seasons via automated controls in ten zones.
This is not the first honor bestowed upon the Terminal; it received a 2012 Merit Award for design excellence from the American Institute of Architects North Dakota Chapter.
