The district heating and cooling system will replace coal boilers, cutting the university's carbon footprint in half and saving $2 million a year. It's also a learning opportunity for students.
With 3,600 bore holes, a massive new ground-source heat pump system at Ball State University is going to become the largest system of its kind in the U.S. when it is fully operational in 2014. It is already cooling 47 campus buildings and heating 20, and it will eventually heat and cool all of them, according to the university.
It's part of Ball State's long-standing leadership on green campus issues, including the interdisciplinary Greening of the Campus conference series, in its ninth year, where the new ground-source system was recently dedicated.
