energy usage effectiveness (data center) (EUE)
Energy Usage Effectiveness (EUE) is a key figure used to evaluate the energy requirements of data centers, comparable to Power Usage Effectiveness( PUE).
With the Power Usage Effectiveness (PUE), the total consumed energy of a data center is put in relation to the power consumption of the IT systems. Since the PUE parameter is often calculated for relatively short periods, seasonal temperature fluctuations are not included in the calculation. For this purpose, the Energy Usage Effectiveness (EUE) parameter was developed, which maps the ratio over a year and thus eliminates seasonal fluctuations.
