UHE (Ultra High Efficient) Data Center

12 Months PUE = 1.179 (*)

(*) PUE Measurement Levels (Green Grid)

  • L3 Measurement Interval: Continuous
  • L3 Total Facility Energy: Utility Inputs
  • L1  IT Equipment Energy: UPS Outputs


12M PUE = 1,179  highly significant since:

  • DC located in Italy, at 45°N Lat. (45.100°N – 8.863°E), where Dry Bulb Temperature is ≤ 27°C for max 7000 hours per year;
  • 20 years max DBT = 38.9°C (ASHRAE Handbook);
  • Extreme Max WBT = 27.9°C (ASHRAE Handbook)
  • ASHRAE TC 9.9, Thermal and Contamination Guidelines compliancy
  • Uptime Institute Tier IV compliancy with redundant systems/components
  • Current IT load less than 20% of rated design IT load
  • High accuracy in energy measurements (global accuracy class TA + Instruments = 0,3)
  • Standard IT Equipments (no HW custom designed for energy saving purpose)
