Water Usage at AI Scale: Insights from a 100 MW Comparative Analysis
Compute and display WUE (L/kWh IT) next to PUE for every cooling design.
- Dallas WUE falls from 0.42 to 0.22 L/kWh; Paris from 0.12 to 0.06 L/kWh.

Schneider Electric 2026
Compute and display WUE (L/kWh IT) next to PUE for every cooling design.
Open Compute Project Foundation 2026
Fix the ESS architecture (DC or AC coupled, distributed or centralised, backup-only or grid-interactive), write the applicable NFPA 70, NFPA 855 and IEC 62933 parts into the design basis, and consult the authority having jurisdiction (AHJ) early.
Schneider Electric 2023
Keep a jurisdiction rules table, for example Germany with PUE_max 1.2 for new builds and heat_reuse_min rising from 10% to 20%.
The Green Grid 2010
Take annual reused kWh from heat-recovery equipment (heat pumps, liquid-cooling return loops) and compute ERF and ERE.
The Green Grid 2010
Compute CUE as grid emission factor (kgCO2e/kWh, per region and hour) x PUE.
The Green Grid 2011
In the water module, compute WUE_site = annual make-up + humidification water (L) / IT kWh from the hourly cooling model (evaporation ~ heat rejected, cycles of concentration for blowdown).
The Green Grid 2011
Build a self-assessment questionnaire that scores a design or operation 0-5 per area and links each gap to a concrete design option.
The Green Grid 2025
Add a water-stress index from a public water-risk atlas to the site catalogue and use it to weight WUE.
The Green Grid 2025
Put a water-stress rating beside WUE on the site-selection screen.
