That's pretty sweet. My cousin in-law is actually a builder in Marquette, MI, which is on Lake Superior on the Upper Peninsula.

He talks a lot about similar building concepts. I know he takes a lot of pride in building extremely efficient homes. I think I've listened to him talk about heat exchangers for several hours straight before.

He mentioned they can't do geothermal effectively up there because the bedrock is above the frost line. They have less than a few feet of soil in a lot of places before you get down to granite. I imagine geothermal has issues with permafrost that makes installation similarly difficult.

Thanks for the links, I'll definitely check them out.

That's where some of Chlupp's concepts -- building on top of a very large sand base, for example -- might come in handy. He doesn't make use of geothermal (ground-loop) heat pumps though.

These two in particular detail the design logic:

A fair bit of his technology comes from Germany, as does he ;-)

And there are some videos there that run less than an hour. Though I find the two listed to be well worth the time to watch -- information dense. You can skip through bits if necessary.
