Energy Efficiency Upgrades for Fermilab Infrastructure: Federal Energy Management Program (FEMP) Utility Services Case Study (Fact sheet)

At the Fermi National Accelerator Laboratory (Fermilab), originally built in the 1960s, old process and comfort chillers, pumps, and other related central cooling-system equipment were replaced, and pumping configuration changes were made to accelerator heat rejection systems. The employee office space and a 'process system' for the equipment and accelerators. The new 4500-ton cooling system isexpected to use 40% less energy and is free of ozone-depleting chlorofluorocarbons. Energy savings of 20 million kWh and a deamnd reduction of about 2.5 megawatts are expected, resulting in estimated cost savings of $900,000 per year.
