ASHBURN, Va. — For a decade, U.S. data centers were air-conditioned warehouses with expensive electricity. The 2026 AI hall is a plumbing project. Operators said new builds assume rear-door heat exchangers at minimum and direct-to-chip loops for the densest racks.
That rewrite hits every subcontractor. Chillers, CDUs, and leak-detection vendors that used to live on the edge of a data-center bill are now on the critical path.
Landlords who cannot offer liquid will not merely lose a tenant. They will lose the only tenant class still paying 2021-style rents.
