Data Center Water Usage Effectiveness

Striking a balance with resource consumption in your data center facility could prove to be a herculean task.

Data center water usage effectiveness.

The units of wue are liters kilowatt hour l kwh. At most data centers there is a trade off between water and energy consumption. So an effective water conservation plan should be adopted in data center facilities to ensure fair usage of this natural resource which is more precious than electricity. The wue is a metric that divides the annual water usage by the it power.

To water use in processes due to site operations and source energy generation similar to scope 1 and scope 2 greenhouse gas ghg emissions2. Where no water is used for cooling the wue has a value of 0. Water usage effectiveness wue the metric for water usage in the data center is defined at a high level as. Wue water usage effectiveness is a metric developed by the green grid to help data centers measure how much water a facility uses for cooling and other building needs.

Wue is still a fairly new sustainability metric a natural extension of pue power usage effectiveness the most used metric related to data center energy efficiency. How does it measure water usage effectiveness. Traditionally data centers have focused on power usage effectiveness pue to cool facilities however we re seeing water usage effectiveness wue become a critically important metric as. The most frequent example of this happens when operators seeking to reduce power consumption switch from computer room air conditioning crac systems to evaporative cooling systems.

Wue is simply defined as annual site water usage divided by it energy usage.
