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

 

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

  • Regional Grid Greenhouse Gases: How much greenhouse gas does this facility’s local electrical grid emit while generating electricity?  (Useful for Location-based greenhouse gas reporting)
Greenhouse Gases 2004 2007 2012 2016 2018
MTCO2/MWh 0.520 0.507 0.423 0.365 0.337

The carbon-intensity of the grid has improved about 2.7% points per year over the last 14 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)?
Grid Renewables 2004 2007 2012 2016 2018
Percent from renewable sources 3.7% 2.7% 3.4% 5.6% 7.7%

This has been increasing about 0.6% points per year over the last 14 years of published data.  Based on US EPA eGRID data for the SERC Virginia/Carolina subregion (SRVC).
