• Features
  • Water Free Cooling (AKA Low Water All-Star, Water Conservation Hero, Drought-Friendly Cooling
  • Renewable Energy Used
  • Renewable Energy Available

• Reporting
  • Water risk (now, 2030, 2040)
  • Carbon intensity (trends over time)
  • Grid renewables (trends over time)

• 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 9.8 million gallons of water per month to cool them.

• Regional Water Risk: The Raleigh-Durham area faces a medium-to-high risk of water supply disruption, which is expected to become low to medium risk in the future.  Unlike many other data centers, CyrusOne’s Northern Virginia – Sterling V facility does not use water for cooling and is therefore insulated from regional water risk, both current and future.

This facility is a legacy site that doesn’t use CyrusOne’s Zero Water Consumption Cooling but it still consumes less water than most data centers.  We are examining opportunities for reducing water use at this facility.

• Regional Grid Greenhouse Gasses: How much greenhouse gas does this facility’s local electrical grid emit while generating electricity?  (Useful for Location-based greenhouse gas reporting)

The carbon-intensity of the grid has improved about 2.6% points per year over the last 12 years of published data.  Reported by the US EPA eGRID for the SERC Virginia/Carolina subregion (SRVC).

• Regional Grid Renewables: What percentage of this facility’s local electrical grid is from renewable sources (wind, solar, biomass, hydro, and geothermal)?

This has been increasing about 0.2% points per year over the last 12 years of published data.  Based on US EPA eGRID data for the SERC Virginia/Carolina subregion (SRVC).
