The new metrics for data center efficiency and sustainability

While long considered the gold standard for measuring data center efficiency, PUE is not without its faults. For one, it only takes into account the efficiency of power usage (i.e. the ratio of total facility power to IT power). It can be a good measure of cooling system and facility efficiency, however, is does not take into account a holistic perspective of the environmental impact of a data center. To truly understand a data center’s impact on a broader environmental level, it is critical to measure the water usage and carbon emissions for which that data center may be responsible – both directly and indirectly.

As always, our All You Need to Know About... series just scratches the surface of a different subject for each entry, and to dive deep into all the data and specifics you'll want to download our corresponding White Paper "A Paradigm Shift in Data Center Sustainability".

The Green Grid defines the following metrics for measuring the efficiency of a data center in terms of its water use and carbon emissions:

Water:
  • WUEsite = Annual Site Water Usage / IT Equipment Energy (in L/kWh)
  • WUEsource = Annual Energy Source Water Usage + Annual Site Water Usage / IT Equipment Energy (in L/kWh)
Carbon:
  • CUE = Total CO2 Emissions Caused by the Total Data Center Energy / IT Equipment Energy (kgCO2eq/ kWh)
