ICF is also airtight - you actually need fresh air intakes designed in, mostly you use a heat exchanger so you don't lose your cold/heat. But in a TEOTWAWKI situation, you could shut that down and isolate the house from zombie virus or clouds of CS tear gas.

Another thing to think about when choosing a building method that I hadn't mentioned is transportation costs. For an earthbagged building, most of the transport costs associated would be if you had soil mix trucked in. About 2.50$/ton delivered in a 15 ton truckload is a figure I've seen mentioned.
Good point, the work you're willing to do, the more you going to save.
One thing you should consider, this being Montana, is straw bale. Lots of those here and if you have a truck you can rent a trailer and transport it yourself, saving you alot of money in the process. Some farmers will sell the straw bales for what it cost them to bale it, making it a cheap method if you transport it yourself. Also, strawbale has excellent insulating properties and you can build a shelter I"d think much quicker because of the size of the building blocks.

The tree supports look great, but wood rots rather quickly in damp
environments, and i want something that is going to last.
so i'm planing on modifying it a bit, its not as environmentally friendly, but
should last a lot longer.
I was also thinking on top of the straw bails, spray
a layer of insulation, then use the hardener that many movie prop's use for foam and
create a rock hard structure, could paint it to look like a big rock, or still cover it with
dirt, but this would add a water proof layer, heck if you wanted you could also spray over
the rock hard cover with a layer of the spray in bed liner, like for pickup trucks and further
improve the water proof.
Although i've had the idea of not such a big hole at top, use a funnel type structure over
the fire in the center so you end up with a 8" or so size hole for the smoke to go out and the
roof is fully waterproof, use a sheet of steel and cut out a circle with a hole in the middle to weld
the funnel to and cover the hole.
One could also use the pipe going up to heat water, thus giving you much cheaper and many times
such as winter free hot water, would have to do some rigging, as well as have a holding tank, and a
pump to circulate it, but there are many solar powered pumps on the market.
If one spent time and thought it out this could be a totally off grid home, with all the comforts we
are use to.
