Sacramento International Airport’s new Terminal B received LEED Silver certification, airport officials announced Tuesday.

The terminal is the largest in the United States to receive the Leadership in Energy and Environmental Design certification from the U.S. Green Building Council, according to a press release.

“Achieving LEED Silver certification on two buildings this large, with such intense daily public use, speaks to the vision and collaboration of the airport and its partners,” said G. Hardy Acree, director of airports for the Sacramento County Airport System.

Nicknamed “The Big Build,” the $1.1 billion project was completed in October. Throughout the building process, officials stressed the importance of using sustainable materials and environmentally friendly designs, including glass ceilings and walls that allow for enough natural light that electric lighting use is minimized.

Other aspects of the design included a heat-reflecting roof and energy-efficient shade devices.”

Additionally, nine acres of asphalt were replaced with drought-tolerant landscaping.

“Green technology is a cornerstone of the next economy,” said Don Nottoli, chairman of the Sacramento County Board of Supervisors. “Terminal B is an outstanding example of what can be achieved when technology is combined with a beautiful, functional building which will serve and support our regional economy.”
