Achieving higher building performance is pretty simple if you're retrofitting from a fossil fuel to a geothermal system. At best a fossil fuel system is 80-98 percent efficient, but a geothermal system is 400-500 percent efficient depending on the design of the system.
Proper design is the key to answering this question. Here is where the contractor can shine.
