Efficiency, engineered in from the first drawing.

PUE, WUE, and carbon intensity are measured for each project. The basis is published with the design. No single figure is stated here for every climate.

PUE

Drag to set PUE.

Example: 100 MW IT load.

PUE 1.30 · 130 MW from the grid · 30 MW to cooling and losses.

Measured per project. PUE is facility energy divided by IT energy. The target and its basis are set with the design. Supply air stays inside ASHRAE guidance. Free cooling runs where the site allows.

WUE

Sealed loop

Water use, measured per project. No portfolio figure is stated here.

  1. One-time fill

    Sealed circuit. Top-up only for maintenance.

  2. Free cooling first

    Ambient air carries the heat when the climate allows. Fans and pumps still run.

  3. Adiabatic pre-cooling

    Adiabatic pre-cooling, with minimal water, only on the hottest hours.

  4. Liquid to the rack

    Direct-to-chip liquid cooling, from 50 kW racks to the newest few-hundred-kW racks.

Carbon intensity

Firm capacity is generation by others and the grid. Carbon intensity is measured per project. No portfolio figure is stated here.
