Energy Management


O'Hare International Airport

The CDA monitors the electricity and natural gas usage for the airport and strives to be more energy efficient.

  • Utility meter inventory allows for energy tracking: 700+ electricity meters, 100+ natural gas meters
  • CDA facilities have a documented 2010 energy baseline
  • Energy usage reports are sent to the CDA facilities staff to actively manage building systems and equipment
  • Metric: percent reduction of energy usage per passenger (2016 result from 2010 baseline)
       - 14.8% electricity reduction
       - 4.6% natural gas reduction

The CDA was awarded a $2,300,000 two-year energy efficiency grant from the State of Illinois Department of Commerce and Economic Opportunity. This grant supported several energy efficiency projects: roadway lighting, both interior and exterior terminal lighting, office lighting, parking garage lighting, chiller upgrades, and the installation of variable frequency drives (VFDs). These projects are anticipated to save over $1,500,000 in electricity costs annually.


Midway International Airport

The CDA monitors the electricity and natural gas usage for the airport and strives to be more energy efficient.

  • Utility meter inventory allows for energy tracking: 150+ electricity meters, 40+ natural gas meters
  • CDA facilities have a documented 2010 energy baseline
  • Energy usage reports are sent to the CDA facilities staff to actively manage building systems and equipment
  • Metric: percent reduction of energy usage per passenger (2016 result from 2010 baseline)
       - 23.4% electricity reduction
       - 42.3% natural gas reduction

The CDA completed construction of the Consolidated Rental Car Facility achieving U.S. Green Building Council LEED Silver Certification and installed 24 roof-mounted 1-kilowatt wind turbines atop the Midway Economy Parking Structure. The wind turbines are anticipated to save over $9,000 in electricity costs annually.
