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 is expected to use 40% less energy and is free of ozone-depleting chlorofluorocarbons. Energy savings of 20 million kWh and a demand reduction of about 2.5 megawatts are expected, resulting in estimated cost savings of $900,000 per year.

The use of dessicant materials for cooling and dehumidification is an effective, economical, environmentally safe method for meeting indoor air quality standards established by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). To maximize the technology's potential for reducing energy consumption and improving indoor air quality, DOE established the Advanced Desiccant Cooling and Dehumidification Program. The National Renewable Energy Laboratory partners with industry to support and educate industry users, as well as to support technology transfer and benchmark current performance.
