    I have an uncle that built an ICF house into the side of a hill and uses a low pressure wood pellet boiler to heat the basement slab. The house could almost stay warm most of the winter with just a couple of candles lit upstairs. I helped put in the foundation with him and would certainly go the same route if I built in a rural area.

    That dude is not really a good example of how an ICF home would normally be built. He's closer to what @eblend is doing, hand-built, or self-built home with a lot of unique features.

    Cool bump though. I still think ICF is a really smart construction technology, very well suited to harsh climates.
    Is cost for ICF still 2-3x than normal build (from ur 2014 post). I don’t know much ICF for industrial builds tho… (usually tilt up or precast)… that’s what I was search for, for a future build. But of course nothing beats (cheapest) for steel structure for industrial

    I feel ICF is a waste oi 6" of concrete. Concrete is a poor insulator, but a good thermal mass, but on a ICF house, you essentially have the concrete in the middle, negating this benefit with only 2.75" of foam in and out. If you lived somewhere with tornado's and hurricanes, sure, go for it. It will be the only house standing afterwards lol.

    I think in terms of efficiency, SIPS is the way to go, there are many variations around, but in terms of heating and cooling, you get more insulation. Some builders are doing sips panels, then a more traditional timber frame, you can get R38 from a 8.25" XPS SIPS panel and my parents went with 10.25 with EPS foam (R35), and 12.25" EPS panels for the roof (R42).

    You do need dehumidifier for both, along with a good HRV.

    I had a 2012ish bungalow build with ICF in Alberta and I can attest to this. I set the basement (8ft ceiling) slab heat to 20 deg and the furnace rarely kicked in for the first floor. Since I was the second owner I can't attest to initial building costs.

    I've got a friend who runs a structural engineering firm in Regina that does work all over Canada and they big big proponents of ICF construction when financially feasible to do so. it seems like every post on the firm's social media is either some crazy unique feature or an ICF build. I don't know much about them but I know she raves about them

    As far as I know concrete is still more expensive than wood, so yes. Keep in mind the additional costs for using a pumper truck for all of it; a couple of Neanderthals on wheelbarrows doesn't work for ICF pours.

    Once we start paying carbon tax on everything, and we switch to carbicrete, should be cheaper?

    Or foamcrete. Literally a giant foam machine aerating a cement mortar mix. Not as strong, but much better insulating values.

    There are people making "foam concrete". It's interesting stuff. Basically a giant bubble machine foaming a cement or mortar mix. Some are fiber reinforcing it with chopped strands of various fibers. Yes, fiberglass, but also stuff like Hemp. It is not as strong as concrete, but now acts as an insulator and you use much less material.

    I worked at lumino down by chinook mall. We used a pump truck for our icf pours, up until like the 7'th or 8'th floors. After that it was all bucket and crane. And let me tell ya some of the blow outs we had were wicked. Im afan of icfin the sense that its super easy to work with but uh... other than that hard no.

    If you had blow outs, it wasn’t done right. It takes a shitload of work to brace it properly, even for small residential pours (e.g., an addition to a house), and that’s a great place to cut corners… which is something pretty popular with lots of builders.

    I dunno. We got a 25X25 raised (3ft) deck poured for less than what it would have cost to build a wooden one.

    Hell 85ft of fence was $14K with 4x4 posts. Told them to fuck off. 6x6 posts was another $2K. Told them to fuck off again.

    That's pretty outrageous. TIL $wood >= $concrete. Either that, or your fence/deck builder is trying to raw dog you.

    Curious what beyond thinks of this idea. Maybe bundled with some solar panels direct attached to some heating elements (no battery) but of course with fan running on battery. For ultra-remote locations, instead of or supplementary propane.
