Geothermal Projects in University of Illinois at Chicago


Renovation of Grant Hall on UIC campus on September 19, 2007 by instituting a geothermal energy system with vertically configured pipes.  Since its inception, a temperature of 70-72 has been maintained at Grant Hall which has a floor area of 15,000 ft2, and energy consumption has been cut by 50%. The Grant Hall geothermal system consists of 28 bores drilled to a depth of 500 ft. Each bore is 4 inches in diameter, while the pipes have a diameter of 1.25 inches. The piping system conveys water via a conventional pumping system.

Due to the success at Grant Hall, there are now plans to extend this geothermal project to two additional buildings Lincoln Hall and Douglas Hall.

Geothermal Heat Pump

A heat pump is a machine which causes the heat to flow in a direction opposite to its natural tendency or "uphill" in terms of temperature. Because work must be done (energy consumed) to accomplish this, the name heat "pump" is used to describe the device.

Geothermal heat pumps (GHPs) can use the almost constant temperatures (45F to 70F) of soil and water beneath the frost line as an energy source to provide efficient heating and cooling all year long.

A typical heat pump system:
