Dallas – Allen Data Center

• Cooling Plant type and size – Closed loop, air cooled chilled water system (N = 4.5 MW)
• Cooling capacity per cabinet – 150 to 180 watts p/SF (average density)

• Fire Detection – Three stage detection system and data halls and UPS enclosure spaces

• Fire Suppression – Combination wet type sprinkler system in offices and pre-action type sprinkler system in critical and critical support spaces

• VESDA (Very Early Smoke Detection Apparatus)

• Utility capacity – 50 MW
• Utility Voltage – 24,900 (25 kV)
• # of Utility Feeders – 2 each (non-redundant)
• # of transformers on site – 26 Transformers (
  24 each @ 2.5 MW, 1 each @ 1 MW, 1 each at 2 MW)
• UPS configuration & capacity – Distributed redundant, with 4,500 kVA blocks (6 MW)
• Generator Power – 24 each 2.25 MW Diesel (Critical), 1 each 1.25 MW Diesel (House)
• Electrical capacity allowed per cabinet – 150 to 180 watts p/SF (average density)

• Physical – 8′ high perimeter steel ornamental exterior fencing
• Anti-tailgating system with raising and lowering arms at vehicle entrance
• Guards – Onsite guards man a dedicated Security Office at the main entrance (lobby) to the building
• Electronic – A security system consists of various devices (card readers, badge readers, bio-readers, etc.) either permitting or denying access to various parts of the building
• Access parameters are controlled through local onsite guards
• Standards Compliance and Certifications – All local codes and standards are adhered to. CyrusOne standards and regulations are also in place for both safety and fire protection

• Construction Type – Concrete Tilt-Panels with slab on grade. Steel truss overhead structure with modified built-up roofing membrane to meet specific wind up-lift parameters.
• Building Type – Critical Services
• Floor Load Capacity –
  • Data hall white floor space is 320lbs p/SF
  • CRAH gallery floor capacity is 2,000lbs p/SF

• 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.  An average US data center of the same size typically consumes over 1 million gallons of water per month for cooling.
• Regional Water Stress: The Allen area currently faces high water stress, which is projected to remain high in the future.  Unlike many other data centers, CyrusOne’s Dallas – Allen facility does not use water for cooling and is therefore insulated from this 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	0.644	0.568	0.518	0.458	0.423

• The carbon-intensity of the grid has improved about 2.3% points per year over the last 14 years of published data. Reported by the US EPA eGRID for the ERCOT subregion (ERCT).
• 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	1.3%	2.7%	8.6%	14.5%	18.2%

  This has been increasing about 1.2% points per year over the last 14 years of published data.  Based on US EPA eGRID data for the ERCOT subregion (ERCT).
