General Motors

General Motors is a leading global auto manufacturer. It sells vehicles under the brands Buick, Cadillac, Chevrolet, GMC among others.


GM hired Worthington Energy Innovations to design energy system retrofits at their Rochester, NY plant, the Livonia, MI plant and the Drayton Plains, MI plants. At the Rochester, NY facility Worthington’s engineering team shut down steam systems and converted them into gas fired closed hotwater loops. The Livonia, MI project involved retrofitting a plant already using gas fired boilers by redesigning its energy system. The Drayton Plains Plant was converted to Worthington’s innovative ductless building pressurization system.


GM realized more than $7,000,000 in annual savings from these projects with an average ROI between 2.5 and 3.5 years. Worthington Energy Innovations' work at GM’s Rochester plant showcased the newly patented “Bigfoot” air-handling unit that forms the backbone of Worthington’s ductless heating and cooling strategy.
