The geothermal system will reduce the university's energy consumption dramatically during the life of the buildings, providing about 60 percent of the heating and 30 percent of the cooling needs of south campus residence halls.
Sustainability at Ohio State
There are more than 400 wells drilled to a depth of 550 ft. in the South Oval and Hale Green. The Ohio State University is a recognized leader in developing durable solutions to the pressing challenges of sustainability. In 2015, with input from faculty, staff and students, the university established strategic sustainability goals to support Ohio State's core mission of teaching and learning, research and innovation, outreach and engagement, and resource stewardship, thus instituting a concrete set of goals that the university will use going forward.
