Prefab house - yes or no?

Why should a solid construction get an ETICS? Ours is not getting it, and the energy calculation report certifies that the house easily meets the standards. With ease. Wall structure Ytong plus plaster. Done.

Why should a solid construction get an ETICS?

Now please help me out, is ETICS therefore a rare exception in solid construction?

I think so, yes. At least in northern Germany. People here all build with Ytong, I think 7 out of 10 use facing bricks, the others plaster. I only see Styrofoam insulation in case of subsequent old building insulation.

That's how it is

You can't talk about advantages on one side when the other has the same advantage.
I wrote further above that each option has its own advantages, but it is up to the builder to decide individually.

By the way, I only provide neutral information; what one makes of it, the reader must find out for themselves

well, then we've cleared that up now.

so I suspect that there is also a lot of construction with ETICS, then the wall thickness can be thinner to achieve the same insulation value, if you build without it, i.e. monolithically, you need thicker stones to achieve the same values. however, I do not know in the end whether you have thinner or thicker wall thicknesses. I see it as many have already said: every construction method has its advantages and disadvantages, you have to consider for yourself what bothers you and what you find good

The wall thicknesses are probably very similar. We decided on calcium silicate brick because it is significantly more stable/compressive resistant, and there should be fewer settlement cracks (by the way, we have none after 3 years) and it has advantages in sound insulation as well as fastening options. The room temperature is also probably more constant, since a lot of mass can absorb some temperature or energy (in summer), but then also stores it. This can of course be a disadvantage during longer heat periods in summer, but so far it has never been uncomfortably warm. In winter, this is more of an advantage. Our heating once had a malfunction and we didn't notice it for a whole day; only when the shower water stayed cold did we realize it. The room temperature had fallen less than 2 degrees by then. In other words, if the heating fails, you don’t immediately "freeze." From what we were told, it is easier to meet KfW criteria with a prefabricated house, but if the heating fails, the house cools down very quickly (which can of course be an advantage in summer, as you can cool it down faster at night).
