DFT ACC7 Technology Center Wins Brill Award for Data Center Design


DuPont Fabros Technology's ACC7 has been chosen as one of Uptime Institute's 2015 winners of the Brill Awards for Data Center Design. DuPont Fabros Technology, Inc. (DFT) is a leading owner, developer, operator and manager of enterprise-class, carrier-neutral, large multi-tenant wholesale data centers.

The Brill Awards recognizes IT efficiency in five major categories - IT Systems Efficiency, Data Center Facilities Management, Data Center Design, Operational Data Center Upgrade and Product Solutions. The Data Center Design category focuses on data center capital projects that demonstrate the ability to deliver significant energy and resource efficiency and acknowledges the newest, most innovative data center designs.

One of the largest data centers in North America, ACC7 boasts 446,000 gross square feet with a total critical power capacity of 41.6 megawatts when fully developed. Each of the 28 computer rooms are equipped to deliver an average critical load of 1.486 megawatts with the ability to increase density to offer up to 2.0 megawatts based on a customer's requirement. Ultimately, the design achieved an industry-leading PUE of 1.15, as calculated on an annualized basis.

CCG served as the Prime Contractor for the data center Basis of Design and Electrical Engineer of Record for this project. Features of the electrical design include:

  • The design utilizes Underground Medium Voltage Distribution throughout the building, including to the substations for essential power and Power Distribution Units for critical power. 
  • The indoor Medium Voltage Switchgear are designed to be UL listed arc-proof switchgear, reducing the Arc Flash Hazard in the UPS Rooms. 
  • The input and output to the UPS Modules at 5kV, reduces the number of conduits and wire to the PDUs. 
  • The PDUs include less-flammable liquid filled transformers and IT power distribution at 415Y240 volts, reduces the installed cost of the distribution within the Computer Rooms. 
  • The essential transformers are also less-flammable liquid filled transformers, installed in the UPS Rooms. 
  • The essential power is distributed at 480 volts.
