| Fact | Value | As of | Basis | Source |
|---|---|---|---|---|
| Cooling | Lake Lugano water drawn at 45 m depth at about 6 C via a 2.8 km pipe; 460 l/s reaches CSCS; first circuit sized for 14 MW of computers, second mid-temperature circuit for a further 7 MW CSCS fact sheet dated 2015-06-25; return water to the lake capped at 25 C. | 2015-06 | Operator stated | cscs.ch |
| IT power | 11 MW Power supply at the time allowed about 11 MW of computers, extendable to up to 25 MW (fact sheet, 2015-06). | 2015-06 | Operator stated | cscs.ch |
| Machine-room floor area | 2,000 m2 Machine room area; the separate five-storey office block adds 2600 m2. | 2015-06 | Operator stated | cscs.ch |
| PUE | 1.25 Design target ceiling (below 1.25), not a measured value; fact sheet says cooling would otherwise be about a third of electricity use. | 2015-06 | Operator stated | cscs.ch |
