Carteret Colocation Data Center
This Colocation Data Center expansion project consisted of two sequential Additions of the three phased additions to an existing 85,000 square foot legacy data center. The first phase was a 28,000 square foot addition to the existing data center. The second was a 32,000 square foot addition built in sequence with the first addition. All the phases were master planned for expansion of the addition to almost 80,000 square feet and the last 30,000 square foot building addition is planned for a final expansion phase on the other side of the building.
The building structure is structural steel frame system with 40’ x 25’ column bays. The shell is fabricated from precast concrete, designed to withstand hurricane and tornado forces in excess of 150 mph.
Electrical Infrastructure systems have 2N system redundancy in Phase 1 and a 3N/2 configuration in Phase 2, with concurrent maintenance and monitoring of the entire electrical infrastructure. A rotary UPS diesel power generator system was utilized for Phase 2 with the Mechanical loads backed up on that system.
Mechanical cooling infrastructure is designed with the use of air cooled chillers and dry coolers for free cooling during low temperature periods. This system saves considerable energy whenever the air temperature is 60 deg F. or lower which occurs approximately 4,500 hours/year. Since it is a glycol closed loop system it saves water throughout the year. Phases 1 and 2 share the entire refrigeration plant and a common air plenum for ultimate redundancy and capacity. The AHUs are roof mounted, VAV controlled and they feed the raised floor via a common vertical plenum in the center of the building. All chillers, pumps, and AHUs are provided with variable speed drives; the entire system is configured as N+1 redundant and has a redundant glycol pipe loop.
