US Department of Transportation
Washington, DC, United States, Vereinigte StaatenOpened in September of 2006, the new United States Department of Transportation headquarters in Washington D.C. consists of a shared underground parkade and two similar towers of 8 and 9 storeys. The complex is the first cabinet-level headquarters to be designed and constructed in the US capital in over 3 decades. Accommodating over 5,000 federal employees, the 11-acre site spans two city blocks near the Anacostia River.
To control the 2 million square feet of the US DOT headquarters, two large central plants serve 94 air handling units, 90 fan coil units, and over 2,000 variable air volume terminal units. In the event of an opposite-building failure, each central plant is sized to serve mission-critical equipment in both wings. The native BACnet® system was selected after an exhaustive procurement process based heavily on the capabilities of the Reliable Controls® MACH System and Pritchett Controls, the local Reliable Controls® Authorized Dealer. In addition to providing local control for the equipment listed above, the Reliable Controls® MACH System integrates packaged pump skids, variable frequency drives, lighting controls, and power monitoring via BACnet®.
