Aren't today's houses significantly over-dimensioned?

Yes, standing with a particle board against or with the wind at 16m/s is not done without consequences, unless you are very strong But imagine then sending up 150 m2 of sail on a sailboat in that wind. Then, my friends, we are talking about an adrenaline rush, I can tell you. On one occasion, on a slightly smaller boat that didn't have quite so much sail, we pulled away from a RIB Yihaa

The difference with the boat is that it doesn't stay fixed but takes off ahead of the wind. If you then subtract the apparent wind which comes from ahead from the wind that comes from behind, you get a relative wind that is much weaker. d^_^b

However, if you "fix" a boat in the waves and no longer surf, both the sail and the mast risk being damaged quite quickly in such wind speeds.

There you go
Unfortunately, it's not part of the standard solutions. Where did you find the image? One of the insulation manufacturers?

That's right. But instead of building load-bearing frameworks in 220x45 with thermal bridges, you should be able to build smarter with an external load-bearing structure of 95x45 or 120x45 and an internal wall of 95x45 with an unbroken insulation layer of about 70-95mm thick between the two walls.

That's exactly what I thought too, so I built my latest house that way. However, it was quite cumbersome.

I thought it was a standard solution for passive houses to handle insulation without thermal bridges? (http://www.granback.se/ in this case.) I've also seen it built as a demo wall at the university in Växjö. There was a small array of different wall constructions there.

Otherwise, the method is old for additional insulation on the inside of a wall. You frame up a new wall a bit out from the old one and then get 45-70 mm insulation between the old and the new wall with full insulation coverage.

I thought the 300 m2 in the first post was oversized.

Otherwise, one should also consider that a structure should be able to withstand fire for a while before it collapses, and also some rot in case of leakage. Therefore, it might be appropriate to oversize a little.

The difference with the boat is that it is not fixed but moves ahead of the wind. If you subtract the apparent wind coming from ahead from the wind coming from behind, you get a relative wind that is much weaker. d^_^b

However, if you "fasten" a boat in the waves and no longer surf, both the sail and mast risk being damaged fairly quickly in such wind conditions.

You are not fixed when you hold a board either, but a house is, of course. The forces on a boat in the 6-ton class with that amount of sail should not be underestimated, and that’s exactly why it moves, significantly

You only surf down the waves if there are any to speak of, and definitely not on every one, and not with just any boat unless you're out on the North Sea with 5-meter waves. We surfed with an 8-ton boat from the early 80s once; the roar of the wave that broke around us and foamed around the entire boat up to the deck was so deafening that it wasn't even worth shouting to the others in the cockpit. The mast usually holds; it's the sails that give way if you're unlucky. This usually happens because they start flapping in the wind and tear apart due to the fluttering movements, rather than the wind simply tearing them apart, and this can happen even in lighter winds. Yes, that was a bit off-topic, back to the subject perhaps.

Did you place the load-bearing part of the wall on the inside or outside?

Perhaps you can answer here:

Since this is actually a bit off-topic here.

 

[andersmc]

The answer is there.

How did you think now? My old wall was hardly oversized...

I mostly read environmental forums and thought the thread would be about the houses being oversized, not the construction.

Quite right. If you only read the headline.
