Geothermal Retrofit of Illinois National Guard's State headquarters Building
The goal of this project was to assess the feasibility of utilizing mine water as a heat sink for a geothermal heat pump system to heat and cool the 74,000 sq. ft. Illinois National Guard State Headquarters’ building in Springfield Illinois. If successful, this type of system would be less expensive to install than a traditional closed loop geothermal (ground source) heat pump system by significantly reducing the size of the well field, thus shortening or eliminate the payback period compared to a conventional system. In the end, a conventional ground loop was used for the project.
