ACC7 at 21625 Gresham Drive is the largest building on the Ashburn Corporate Campus and the point where its design changed. It carries 41.6 MW of critical load across 238,000 sq ft of raised floor within 446,000 sq ft, divided into twenty-eight computer rooms of roughly 8,500 sq ft, each provisioned between 1.0 and 2.0 MW and holding about 378 cabinets. It was the first building here to abandon the raised floor entirely in favour of mandatory hot-aisle containment, and the first to distribute power at 4,160 volts through oil-filled medium-voltage PDUs of 1.5 MW, which run at 99.6 per cent efficiency against 97.5 for the dry units they replaced. Annualised PUE is 1.15.
