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


Two Madison-area data centers operated by American Family Insurance are cooled by chilled water loops with redundant cooling units to eliminate single points of failure. American Family has worked with Vertiv to develop a plan to upgrade its cooling systems for energy efficiency and to estimate the attainable savings. The goal was to find ways to reduce energy use without introducing new points of failure or taking down the facility during the upgrade.


  • This upgrade improved American Family’s data center efficiency, freed up stranded capacity and improved the manageability and visibility of equipment.
