It's apparently possible to do it to Passivhaus standards, but I don't know what you need to tweak to get there. It would be an interesting exercise to try, though.
It's the sort of thing that's got me thinking that the next time I need to build a garden shed I'll give it a go. Anything that doesn't need foundations, like a deck with a roof on an existing concrete pad, or similar, I'd give it a go to get some experience with it. Round here that wouldn't need planning permission so it's comparatively low-risk. Just need to make sure whatever I did to replace the ties into the foundation blocks was suitable, but that doesn't strike me as beyond the wit of man.
I looked at some similar ideas a while back. Screw piles are a good option for a stable base on uneven ground. Insulation requires coming up with a compatible design for the exterior walls to accommodate 4-6 inches of insulation and then rain screen on top of that. Top and bottom not so hard. Air sealing is quite a trick to do without compromising on disassembly-ready construction by using tape. Picture windows are a challenge, there's nothing really suitable available at least at US hardware stores. Not a problem for a shed but kind of in conflict with the motivation behind the system.
