Data centre PUE, WUE and CUE
Measure data centre energy, water and carbon efficiency.
Sustainability & ESGHow it's worked out
- PUE = facility energy ÷ IT energy. WUE = water ÷ IT energy. CUE = CO₂e ÷ IT energy
- Annual totals, IT energy measured at the UPS output or better
NotePUE says nothing about how efficiently IT uses its energy; pair it with utilisation.
