Reducing Your Data Centre Carbon Footprint Best Practise No. 4

Track data centre sustainability metrics

Most data centre professionals are familiar with Power Usage Effectiveness (PUE), which is the ratio of total facility energy to total IT equipment energy. The closer to 1.0 your PUE is, the more efficient your data centre is.


PUE is certainly one of the most important KPIs to gauge your efficiency efforts, but there are other KPIs you should measure for the most complete picture of how sustainable your data centre is.


Here are a few of them:

  • Cabinets Compliant with ASHRAE Standards – measures how much progress has been made towards ideal environmental conditions calculated by Racks in ASHRAE Recommended Range / Total Racks.
  • Carbon Usage Effectiveness (CUE) – Measures the overall sustainability of your data centre from a carbon footprint perspective. The carbon footprint of a data centre is defined as the carbon emissions equivalent to the total amount of electricity a particular data centre consumes.
  • Data centre Space Efficiency (DCSE) – Measures how efficiently your data centre space is used.
  • Stranded Power Capacity Per Rack – Measures how much additional equipment can be deployed in existing cabinet resources
Digital Age

Measuring your data centre sustainability metrics enables you to capture the effect of changes and to determine if you are achieving improvements in your data centre sustainability. Currently, there are no efficiency requirements for data centres, unlike individual computer servers.


DC Metrics

“Carbon-neutral energy sources and energy-efficient digital technologies are available today, and it’s through appropriate methodologies, industry commitment and policy enforcement that broad adoption can be driven,” said Benoit Revaz, Swiss Federal Office of Energy. “We welcome projects such as the Swiss Data centre Efficiency Label, which can help to lessen the negative climate impact of one of the digital backbones of our society. We encourage and support organizations and nations worldwide to undertake similar efforts.”


Considering the exponential growth of data volumes and data traffic projected in the next few years, methodologies for measuring and managing data centre efficiency are needed to significantly reduce carbon emissions and energy consumption.


In the last decade, global internet traffi­c increased tenfold and data centre storage capacity increased by a factor of 25. To grow capacity sustainability, green data centres and cloud operators are making incredible advancements in energy effi­ciency. They are deploying state-of-the-art hyper-effic­ient equipment and cooling technology, generating renewable energy onsite, and pursuing other innovations like building data centres underground and underwater, developing artificial intelligence that can predict environmental conditions and optimize operations, and reusing waste heat to cool nearby homes and buildings.

Data Growth

Measuring data centre sustainability metrics and driving energy efficiency isn’t just for hyperscalers. All data centre managers need to improve efficiency, reduce operating costs, and comply with corporate and governmental sustainability initiatives.
