Overview
This existing four-story 50,000 SF building has withstood many renovations over the years. This latest effort consisted of approximately 7,500 SF for the conversion of an existing raised floor data center into a new state-of-the-art Regional Operations Center (ROC), complete with two mission rooms (each with a 12' long video wall), tiered seating, Surge Support, a common Watch Room, and a SCIF. Support space for the ROC included various administrative / work areas, a centralized LAN Room, and 15-person video-conferencing center.
Despite having ample heating and cooling capacity within the building, the project scope mandated that the ROC and it support spaces be supported with its own m/e/p infrastructure, independent form the remainder of the building. To accomplish this directive, heating and cooling was provided via new water-source heat pumps for the occupied spaces, while water-cooled Computer Room Air Conditioners (CRAC) were provided for the 1,500 SF LAN Room. Two new closed circuit coolers were provided on grade, immediately adjacent to the building, while office space was converted into a Mechanical Room to house the pumps, small boiler, chemical treatment, and a 100% outside air AHU complete with energy recovery.
As described above, the electrical system for this renovated program space was to be completely independent of the existing power system distribution. Normal power was provided from the existing and extended to a new automatic transfer switch, which in turn feeds a new switchboard. A new 1,000 kW diesel generator (complete with sub-base fuel tank and sound enclosure) was provided on grade within the same enclosure as the new closed circuit coolers. A new UPS system was also provided, consisting of multiple units operating in parallel in an N+1 arrangement. Power distribution for the LAN Room and the ROC occurs beneath the raised access flooring, terminating with flush mounted pre-wired floor boxes.
