Verifying Our Design

We compared our design with 12 other existing geothermal or net-zero sites. The sites match and verify our design closely.

We are not surprised because of the simple law of thermodynamics at play here. That the rate of energy transfer is proportional to the temperature difference, thermal conductivity, and the length of the geothermal wells.

Q=kl(Tf-Tg)

In each operating geothermal site, we can determine the required length of the geothermal wells (l) in terms of the temperature of the ground (Tg), the temperature of the fluid from the building (Tf), the ground thermal conductivity (k), and the amount of heating and cooling (Q). This last term is proportional to the size of the building.

Summary: A greater heating and cooling load requires a greater geothermal capacity.
