Partial PUE (pPUE) is a variant of PUE that measures energy efficiency for a defined subsystem or zone within a data center rather than the whole facility, calculated as the total energy of that boundary divided by the IT energy within it. It is useful for comparing efficiency of specific areas such as a single hall, containment or cooling system.
