Datacenter Efficiency Metrics: NCPI Component Loss
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.
| metric category | item name | description | unit | value numeric (varies by item) |
|---|---|---|---|---|
| NCPI Component Loss | CRAC_Full_Load | CRAC unit – total loss at full load as percentage of IT load | percent | 9 |
| NCPI Component Loss | Chiller_Plant | Chiller plant – total loss at full load as percentage of IT load | percent | 32 |
| NCPI Component Loss | Generator_Standby | Generator (standby) – fixed no-load loss as percentage of IT load | percent | 0.3 |
