Uptime Institute’s reported DX-mode PUE example in its June 2016 water discussion
~1.40 (reported DX example)observed
| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | A reported DX-mode operating example. The article’s separate water-chiller comparison assumes 1.60; those two numbers do not define a legacy-air population range. |
| Caveat | This historical example is not a promised PUE for an air-cooled hall. |
