Data Center Water Usage Effectiveness

How does it measure water usage effectiveness.

Data center water usage effectiveness.

The units of wue are liters kilowatt hour l kwh. Wue is simply defined as annual site water usage divided by it energy usage. 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. Water usage effectiveness wue the metric for water usage in the data center is defined at a high level as.

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. The wue is a metric that divides the annual water usage by the it power. 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. At most data centers there is a trade off between water and energy consumption.

Where no water is used for cooling the wue has a value of 0. It equipment energy annual water usage wue 1. 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 units are liters kwh.

To water use in processes due to site operations and source energy generation similar to scope 1 and scope 2 greenhouse gas ghg emissions2.
