Digital Realty 44521 Hastings Drive (ACC5)
44521 Hastings Drive, Ashburn, VA, 20147, US
ACC5 at 44521 Hastings Drive in Ashburn was described by its developer as the prototype for its ground-up projects, on the strength of its power capacity and flexible design. It carries 36.4 MW of critical load within a total electrical load of 59.6 MW, fed at 34.5 kV from two separate points into sixteen 5 MVA pad-mount transformers, across 176,000 sq ft of raised floor in a 360,000 sq ft building. The cooling plant is built for scale: sixteen chillers, sixteen cooling towers, 480 CRAH units and half a million gallons of chilled-water thermal storage across two cross-connected plants. The LINX NoVA internet exchange node was built in this building, and the site holds Open-IX certification alongside LEED Gold.
