QTS Irving DC3 Data Center

Microsoft occupies one certified building inside QTS's Irving campus. QTS publishes both building figures and larger current campus figures, which makes it possible to keep the certified building distinct from the site around it.

What changes the reading

  • The building area, data center footprint and redesign area measure different things. The first describes the building, the second describes technical space, and the third describes the area touched by one construction filing.[3][4]
  • The current power and acreage figures cover QTS's full Irving campus. They are not assigned to the Microsoft building alone.[2][3]
  • QTS labels the building's critical power as planned. This page does not treat that figure as delivered load.[3]

Still not public

  • Microsoft's contracted or active load is not public.
  • The building's current occupancy date is not public.
  • Water use attributable to this building is not public.
  • The registry does not identify which parts of the building Microsoft occupies.

The registry entry for this facility comes from the Texas Comptroller's certified list of data centers holding a sales tax exemption. Owner, occupant and operator are roles in that filing rather than descriptions of who runs the building.
