  • CyrusOne Zero Water Consumption Cooling: No water is consumed to cool this facility (such as water towers or evaporative cooling).  Minimal amounts of water are used for humidification and facility maintenance. This facility uses highly efficiency chillers, variable frequency drives, and energy-efficient CRAH units to achieve high-efficiency air-cooled chilling.  An average US data center of the same size typically consumes over 300 thousand gallons of water per month for cooling.
  • Regional Water Stress: While the Norwalk area currently faces low water stress, this is projected to increase dramatically in the next decade.  Unlike many other data centers, CyrusOne’s Norwalk facility does not use water for cooling and is therefore insulated from this regional water risk, both current and future.
