Geothermal: Major Louisville projects at UofL and elsewhere are tapping into the Earth for heating & cooling
"On a rainy spring day, a drill rig punched hundreds of feet into the earth, spilling muddy water out onto a dirt lot at the University of Louisville, where a new engineering school will soon stand.
Aric Andrew, managing the project for Luckett and Farley, trudged through the mud in a hard hat and hi-vis vest, raising his voice over the drill’s rumbling.
Beneath his feet, a construction crew was drilling 160 boreholes, he said, each one running hundreds of feet deep. The loop embraces the relatively constant temperatures found underground, typically between 50 and 60 degrees.
This steady warmth, tapped by a network of looping underground pipes and a ground-source heat pump at the surface, will ultimately manage 99% of the building’s heating needs and a majority of its cooling, reducing energy costs and emissions in the process."
