Here is an overview of some stuff. If you have something specific you are wanting to know or figure out let me know. If you are 100% offgrid, Heat pump water heaters, Heat pump dryers (miele makes some), mitsubishi minisplits can be great (do single units, not multihead units) , basically look for the most energy efficient solutions. In the USA windows are pretty terrible, so look to upgrade those to european style / high energy efficiency windows (You'll pay a lot for them) Typical wall can be R-20, but the windows are usually like R-3.
Another interesting tidbit, without insulation over the studs to prevent thermal bridging you will only get like r20-30 no matter what you do in the wall. So try to insulation on the outside of your house somehow outside of the studs/structure.
