Geothermal at the Campus Instructional Facility (CIF) (Completed)

Description

 

The Campus Instructional Facility (CIF) building is a four-story building dedicated to academic and classroom use, located on campus, west of the Grainger Engineering Library and north of Talbot Laboratory. The geothermal exchange borefield is located in the northwest corner of the Bardeen Quad. The optimized geothermal exchange system will supply the CIF building with approximately 135 tons of heating and cooling capacity, equivalent to almost 65% of the total building energy demand. Based on the thermal properties and monitoring results from the temperature monitoring system, the geothermal exchange system was installed with 40 wells that are 6.1 m (20.0 ft) apart and drilled to a depth of 137.2 m (450.0 ft). The geothermal energy system was activated in January 2021.

The geothermal exchange system is designed to operate for more than 25 years, possibly more than 50 years. The geothermal exchange system will save $45,000 per year in operating the heating and cooling system at the CIF, and projected to be $1.35 million over 30 years of operation.  Performing the thermo-hydro-mechanical analyses and installing the temperature monitoring system, reduced the number of wells needed in the borefield from 60 to 40, which reduced the project payback period from 40 to 28 years (realized through savings in drilling and constructing a larger geothermal borefield). Without these savings, the geothermal exchange system would not have been feasible. 

Background

The Student Sustainability Committee provided approximately 13% of the cost of the geothermal system, and this building project is the first public-private partnership on campus. As the campus works towards being carbon neutral by 2050, this project will not only reduce UIUC’s reliance on fossil fuels, but pave the way for new construction projects to use geothermal systems on campus.
