A pre-retrofit report card helped this major Chicago health care facility chart a smart course of treatment for its HVAC. After improvements for chillers, cooling towers, refrigerants, pumps, and more, the hospital’s central plant upgrade now looks forward to long-term savings, cleaner operations with streamlined maintenance, and better reliability.
