Survey: Which building material/construction method have you chosen?

Real passive houses or just called that? I actually can't imagine that.

Brick > Sand-lime

I have to admit, the term "Ziegel" was not familiar to me at all, or only as a generic term. That seems to be what is called Poroton here.

None of the general contractors we evaluated in the north used that. So it was basically ruled out without prior examination.

Since we are building with a facing brick facade, we had the choice between aerated concrete and sand-lime brick. The choice was clear.

And no, we are not building next to a highway

Poroton is a building material brand. The building material is a perforated brick. filled and unfilled.

Bricks, Poroton, yes, hardly anyone processes stuff like that in SH. Either sand-lime brick or Ytong and the like, such as Hebel, Porit, Hansapor, or similar. I don't understand why sand-lime brick is better than Ytong if it's not about soundproofing. Both contain lime. Only Ytong already provides the thermal insulation, which I still have to glue on with sand-lime brick. Saves an entire step and a bunch of polystyrene or something.

Certifiable. They just didn't have it certified. The certificate costs quite a lot and for what?

There are also several factors involved. We no longer have a passive house.

The general contractor hardly builds KFW 55 houses.

The shell of the passive house was more expensive, but we have no underfloor heating. It is not necessary and not feasible with the installed field trial system (heat pump, controlled residential ventilation).

Due to the solid wood, the retaining wall can be used as a house wall.
Wood stud walls all placed the house 1 meter away from the wall (so one additional wall).

House with lintel wall, ground slab, attic not finished within the thermal envelope, good equipment (roller shutters, lift-and-slide door, parquet floors, low-emission building materials (no construction foams, formaldehyde-free, etc.) 2,400 euros/sqm

Without retaining wall, ground slab 2,000 euros/sqm.

A comparison with a brick-on-brick provider would have been interesting. But when they heard about passive houses in our region, they declined.

You answered your question yourself, it’s about soundproofing and polystyrene on the wall bothers the least, if you look at the new development areas.

The thread should also be about the entire D and not just the north.
