Datacenter Efficiency Metrics: Power Density Parameter
Data center efficiency metrics and benchmarks from Green Grid and Schneider Electric whitepapers. Covers PUE measurement levels (L1/L2/L3), source energy weighting factors (global and US), PUE reporting classifications (Unrecognized/Reported/Registered), NCPI component loss percentages (UPS, PDU, CRAC, chiller, wiring), energy reduction strategy savings ranges, power density parameters by data center type (small enterprise, large enterprise, colocation, cloud, HPC), heat output conversion factors and formulas, and DLC (direct liquid cooling) industry documentation references.
