Electricity consumption at home, what is your consumption?

The main contractor only builds houses with Poroton bricks, and without controlled residential ventilation, he does not know of a mold problem and neither do we.

Possibly because he doesn't know how and doesn't feel like arguing afterwards about why she is loud and doesn't provide the expected effect.

I do not dispute your contribution and with the u-value calculator you can also calculate all that. But vapor diffusion does not mean "breathable" walls. You still need air after all.

So, and what are your electricity consumptions now? Preferably also broken down separately with [Kontrollierte-Wohnraumlüftung]. Then we can possibly save the discussion and everyone can compare with/without [Kontrollierte-Wohnraumlüftung].

I do not deny that at all, the [Kontrollierte-Wohnraumlüftung] brings fresh air in, but there is not automatically a mold problem without [Kontrollierte-Wohnraumlüftung], which some here praise as the only thing that makes you happy. We sleep with the window open all year round and are woken up by the bird song.

Us too. Window open, all good.
