Name or title of the innovative policy, practice, program, or outcome:
Pilot Geothermal Facility on North Campus

A brief description of the innovative policy, practice, program, or outcome that outlines how credit criteria are met and any positive measurable outcomes associated with the innovation:

This project will build a geothermal plant on Hayward Street adjacent to the Leinweber Computer Science and Information Building to supply its heating and cooling. Geothermal systems are considered renewable because of the earth’s constant temperature underground. The Leinweber Building is ideal for this demonstration project because there is sufficient land available for the system and we can learn the dynamics of a geothermal system in our climate. The project will include 100 borings spaced twenty feet apart with underground piping to a depth of 700 feet in an area approximately two-thirds the size of a football field. The system will be an enclosed loop meaning there will be no contact with groundwater or soils. There will be a 4,000 square feet heating and cooling auxiliary building located near the field. As we study comprehensive district geothermal systems for North Campus, we envision this relatively small system could be interconnected as future systems are built.
The geothermal system and the Leinweber Building will be all electric and the first large-scale university building that will not rely on natural gas for heating. Currently, the university is sourcing 200 million kilowatt hours per year from renewable energy. We anticipate the remaining purchased electricity on the Ann Arbor Campus will be from renewable energy sources prior to the completion of the Leinweber Building resulting in a carbon neutral operation.
