The GroundHeatExchanger:Vertical object in EnergyPlus has an input field where you define the ground conductivity, heat capacity, and far-field temperature. EnergyPlus uses these inputs to determine interactions between the ground heat exchanger and the working fluid. There are EnergyPlus objects for other ground heat exchanger models (slinky, pond, surface, and horizontal trench), which have similar input fields to define the ground.
You could also read the Engineering Reference documentation for EnergyPlus that describes G-factors and other parameters that are involved in the heat exchanger calculations.
