As of the end of Q2 2015, Facebook's Prineville data center had a power usage effectiveness (PUE) of 1.078 and its Forest City data center had a PUE of 1.082. [15] In October 2015, Allied Control has a claimed PUE ratio of 1.02 [16] through the use of two-phase immersion cooling using 3M Novec 7100 fluid.
It is an addition to the power usage effectiveness (PUE) definition and was first proposed by Greenqloud. [1] The Green Grid has developed the Power Usage Effectiveness metric [2] or PUE to measure a data centers' effectiveness of getting power to IT equipment. What the PUE tells in simple terms is how much extra energy is needed for each ...
Data center infrastructure efficiency (DCIE), is a performance improvement metric used to calculate the energy efficiency of a data center. DCIE is the percentage value derived, by dividing information technology equipment power by total facility power. [1] [2] [3]
The best PUE a data center can have is 1: an ideal situation, with no extra energy use. When PUE was introduced, studies found that the industry-average PUE was between 2.5 and 3. In more recent studies, the average PUE fell to about 1.7 by using this framework. PUE began the shift of the data-center industry towards energy efficiency. [5]

The perfect efficiency would be a Power usage effectiveness (PUE) of 1.0. [ 11 ] The POD 240a has a refrigerant-based air cooled HVAC system with air-side economization [ 3 ] When the ambient air conditions are cool enough, the 240a uses economizer or free air mode—where outside air can be taken in and circulated inside the modular data ...

An energy efficiency analysis measures the energy use of data center IT and facilities equipment. A typical energy efficiency analysis measures factors such as a data center's Power Use Effectiveness (PUE) against industry standards, identifies mechanical and electrical sources of inefficiency, and identifies air-management metrics.
