This spring, water heated by the Earth will flow through Ball State’s new district heating and cooling system. Ball State will officially commission the nation’s largest ground source, closed loop district geothermal heating and cooling system.

The geothermal conversion will allow Ball State to eliminate its four aging coal-fired boilers. By its completion, the project will provide several hundred contractors and suppliers employment and an opportunity for an estimated 2,300 direct and indirect jobs, according to a study conducted by Ball State’s Center for Business and Economic Research. When the system is fully operational, the university will be able to shut down the boilers, thereby cutting the campus carbon footprint nearly in half. The system will heat and cool 47 buildings and result in $2 million in annual savings. Switching to geothermal will allow us to have a 650 percent increase in system efficiency.
