ENERGY STAR Portfolio Manager

It is computed as the total annual source energy divided by the annual IT source energy. A typical PUE value is about 2.0, which indicates that for every kWh that is delivered to IT equipment, an additional kWh is required for cooling, power supply, and infrastructure. PUE is the basis of the ENERGY STAR performance scale for Data Centers.
