Data Center Water Usage Effectiveness

Water usage effectiveness wue the metric for water usage in the data center is defined at a high level as.

Data center water usage effectiveness.

The new water usage effectiveness wue metric combined with the pue and carbon usage effectiveness cue metrics enables data center operators to quickly assess the water energy and carbon sustainability aspects of their data centers compare the results and determine if any energy efficiency and or sustainability improvements need. Striking a balance with resource consumption in your data center facility could prove to be a herculean task. 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. 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.

At most data centers there is a trade off between water and energy consumption. How does it measure water usage effectiveness. To water use in processes due to site operations and source energy generation similar to scope 1 and scope 2 greenhouse gas ghg emissions2. The units are liters kwh.

Where no water is used for cooling the wue has a value of 0. Wue is simply defined as annual site water usage divided by it energy usage. The units of wue are liters kilowatt hour l kwh. 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.
