    • Regional Water Stress: While the Chicago area currently faces low water stress, this is projected to increase dramatically in the next decade.
    Water Risk and Use Now 2030 Projection 2040 Projection
    Regional Water Stress Low Extremely High Extremely High
    CyrusOne Water Use WUE: 2.10 L/kWh    

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

    • 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 0.706 0.704 0.626 0.564 0.529

    The carbon-intensity of the grid has improved about 1.8% points per year over the last 14 years of published data.  Reported by the US EPA eGRID for the RFC West subregion (RFCW).

    • 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 1.1% 1.0% 3.2% 4.8% 5.2%

    This has been increasing about 0.3% points per year over the last 14 years of published data.  Based on US EPA eGRID data for the RFC West subregion (RFCW).

    • Other Efficiency Measures: The facility has a reflective roof to minimize heat gain from sunlight. It also utilizes efficient Variable Frequency Drives (VFDs) in CRAH units, pumps, air handlers, and Energy Recovery Ventilation (ERV) units.  These VFDs allow the fans and pumps to blow at the minimum speed needed (as opposed to traditional on-or-off units).  The ERVs use exhausted outgoing cool air to pre-chill the incoming warm air, saving energy.
