Reliability: An imperative for all:

→ No design risks must be taken!
→ 99.99% availability (namely 52mn non-availability per year) becomes the norm
→ Centralized control of the operating parameters and critical alarms
→ Availability must be maintained over time
→ Availability must match the acceptable price to be extended to the majority of the rooms


Standards to be adapted to the context:

→ Standards (TIA 942, tiering, Ashrae…): defining the frames of reference
→ Adaptation imperative in the context to be compared with the experience of the operators

  • 99% refers to the fact that the service is unavailable less than 3.65 days per year
  • 99.9%, less than 8.75 hours per year
  • 99.99%, less than 52 minutes per year
  • 99.999%, less than 5.2 minutes per year
