Planning Tools Wanted: Simple ways to measure
data center energy consumption Estimating a data center’s efficiency today helps in current and future cost avoidance
Typical data centers use much more energy than they need to. Short-term opportunities exist to reduce energy use in data centers that are already built. Major energy consumption reduction opportunities exist for new data centers. Data center energy consumption is now a target for environmentally-minded government regulators and for business executives who seek additional ways to cut costs. Which variables have the biggest impact on data center energy consumption costs?
1st key variable: Location A geographical location which experiences extreme temperatures and humidity levels will consume more energy as the data center physical infrastructure systems (e.g., power and cooling systems) work harder to maintain consistent, moderate temperature, and humidity levels. Geographical location will also impact the type of energy that the data center receives from the local utility (is it mostly high CO2 emission coal or low CO2
emission nuclear?).
2nd key factor: IT load IT load reflects how much power the IT equipment in the data center consumes. The higher the load, the more power will be required and the higher the carbon footprint.
3rd key factor: Electrical efficiency Data center systems have traditionally been oversized in order to build in a fat margin for error in terms of estimating data center capacity. Oversizing results in underutilization of equipment which impacts overall data center efficiency.

Measurement tools Automated measurement tools, such as the APC by Schneider Electric Data Center Carbon Calculator, Efficiency Calculator, IT Carbon & Energy Allocation Calculator, and Power Sizing Calculator TradeOff Tools™ (
tools.apc.com) can be accessed at no cost and can help data center professionals understand how they use electricity, and to recognize how changes in efficiency can impact carbon footprint. Although not precise, these tools do provide sufficient accuracy to allow for meaningful analysis of various “what if” scenarios.
