  • 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 efficient chillers, variable frequency drives, and energy-efficient CRAH units to achieve high efficiency air-cooled chilling.
  • Regional Water Stress: The London area currently faces high water stress, which is projected to continue in the 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 2008 2014 2018
MTCO2/MWh 0.497 0.497 0.412 0.278

The carbon-intensity of United Kingdom’s grid has improved about 3.1% points per year over the last 14 years of published data. (2004-1014 data from European Environment Agency, 2018 data from “The European Power Sector in 2018“)

  • 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 2008 2012 2016
Percent from renewable sources 3.6% 5.6% 11.3% 24.5%

This has been increasing about 1.7% points per year over the last 12 years of published data. (Data from the European Environment Agency.)
