Data Center Case Study Before United

United Airlines

When United Airlines needed a new data center, it sought one that could withstand severe weather conditions while maintaining the integrity and security of the cooling requirement. It found the solution in the KyotoCooling® System. The system’s design gives the airline — the world’s largest in terms of scheduled passenger-miles flown — a design that supports its commitment to act in a manner that is both fiscally and socially responsible.


“The new installation, combined with an existing underground data center on United property, will handle all airline operations worldwide,” said Michael Landers, United’s director of design and construction. “It is a very secure data facility that will handle all of our computer operations and our airline operations, globally.”


  • 10-year lifecycle KWh saved: 420 million KWh
  • 10-year lifecycle operational savings: 38 million-plus
  • 10-year lifecycle water conserved: 119 million gallons
  • 10-year lifecycle CO2 reduction: 253,545 tons  Equivalent to 47,839 cars

The new data center on the outskirts of Chicago will be based on N+2 1000Kw KyotoCooling® Units, and the first phase of the capacity provides 4Mw of redundant capacity. “At United, we are committed to leading commercial aviation as an environmentally responsible company by taking actions today that shape an environmentally sustainable future, while continuing to comply with applicable laws and regulations,” said Landers. The facility is the largest enterprise data center implementation of KyotoCooling® in North America.
