Energy Efficiency: Measuring A Facility’s Power Use
While there continues to be a bit of difficulty in trying to quantify the energy efficiency of a data center’s IT systems, the efficiency measurement of the data center facility infrastructure is now is a well-defined metric. It is known as Power Usage Effectiveness (PUE), which was introduced by The Green Grid in 2008. The Green Grid is a global consortium of companies, government agencies, and educational institutions dedicated to advancing energy efficiency in data centers and business computing ecosystems.
