I would like to conduct a non-representative survey, just out of curiosity, to see what has been built in recent years and what is planned for construction soon.
Thank you very much for participating.

Brick > Sand-lime block I have to admit, I wasn’t familiar with the term "brick" beyond a generic sense. It seems to refer to what is called Poroton here.
None of the general contractors we evaluated in the North used that. So it was basically excluded without further consideration.
Since we are building with a facing brick facade, we had the choice between aerated concrete and sand-lime blocks. That made the decision clear.
And no, we are not building near a highway.
Bricks, Poroton, yes, hardly anyone uses those in Schleswig-Holstein. It's either sand-lime brick or aerated concrete products like Ytong and similar brands such as Hebel, Porit, Hansapor, etc.
I don’t understand why sand-lime brick would be better than Ytong, unless it's about soundproofing. Both contain lime. But Ytong already provides thermal insulation, whereas with sand-lime brick, I still have to apply insulation on the outside. That saves an entire work step and a lot of polystyrene or something similar.

Certifiable, but we just didn’t get it certified. The certification process is quite expensive—so what's the point?
There are several factors involved. We no longer have a passive house.
The general contractor rarely builds KFW 55 standard houses.
The shell of the passive house was more expensive, but we don’t have underfloor heating. It’s not necessary and not possible with the installed pilot system (heat pump, controlled ventilation).
Because of the solid wood construction, the retaining wall on the slope can be used as an exterior wall.
All timber frame constructions had the house placed 1 meter (3 feet) in front of the wall (so one more wall).
House with lintel wall, foundation slab, attic within the thermal envelope but unfinished, good features (roller shutters, lift-and-slide door, parquet floors, low-emission building materials—no foam sealants, formaldehyde-free, etc.) costs 2,400 euros/sqm (223 USD/sqft).
Without retaining wall, foundation slab costs 2,000 euros/sqm (186 USD/sqft).
It would have been interesting to compare this with a traditional brick-and-mortar builder. But when they heard “passive house” in our region, they just declined.
