The renovation of Airside 4 consisted of expanding the U.S. Customs and Border Patrol and Federal Inspection Service (CBP/FIS) area to support the conversion of four domestic gates to swing gates, which accommodates both domestic and international travelers. Restrooms were also renovated and a new central energy plant was designed and constructed.
The central energy plant includes four 700-ton chillers and three cooling towers. The CEP was designed to control the operation based on total power consumption. This alternate approach to plant control evaluates multiple schemes based on varying conditions to turn on / off equipment, thus conserving energy. The plant is operating in excess of 10% more efficiently than the existing chilled water plants at the airport, at .79 kW/ton.
