American Family Insurance Increases Cooling Unit Energy Efficiency By More Than 70%

August 31, 2016


For more than 80 years, American Family Insurance has given its customers peace of mind by making their insurance experience easy and convenient. Located throughout 19 operating states, American Family’s independent contractor agents serve as local, expert and trusted advisors to their customers.


American Family Insurance’s leaders wanted to reduce energy usage in their two Madison, WI area data centers – in particular from the cooling systems. The data centers had Liebert Deluxe System/3 chilled water cooling units in operation, with redundant units for backup. All of the cooling units had single-speed fans that ran continuously. While physical space and uptime were not issues, the company wanted to find ways to reduce the energy used to cool these data centers without introducing new points of failure or taking down the data center during the upgrade.


  • Install Liebert VSDs (variable speed drives) for fans on Deluxe System/3 cooling units
  • Add Liebert iCOM™ controls with Liebert IntelliSlot for Deluxe System/3 cooling units

“This upgrade improved our data center efficiency, freed up stranded capacity and improved the manageability and visibility of our equipment”

- Sean Hyland, American Family Insurance, Facilities Program Administrator
