Emission figures are based on UK Carbon Trust calculations: 544 grams of CO2 produced per kWh consumed.

PUEs shown are aggregated figures for a Tier 3 data centre, operating for a year under typical annual weather conditions (data: ASHRAE/CIBSE).

BladeRoom PUE data has been obtained from an independently witnessed live climate testing process. Calculated electrical losses have been added based on N+1 UPS system, N+1 standby generators, 2N transformers, plant ventilation systems and lighting.
