- Operator describes fan-coil wall cooling, hot-aisle containment and a dedicated chiller plant with a closed-loop water cooling system at CH1. This is a design statement, not measured water withdrawal/consumption, zero water use, a water right or a permit. Technical as-of date is unpublished.
Status context. The operator currently describes CH1 as the first named facility providing client IT and connectivity services at the Chicago campus. This supports current service operation, not measured IT draw or every planned phase complete. Generic 24/7 template text alone is not the stage basis; the planned 200+ MW campus is separate.
Published address reference, not a surveyed building or parcel. Published NTT DATA facility address matched to one Census street range within the existing record county. Calculated street reference, not a surveyed parcel, roof, suite, entire campus or property ownership finding.
