Hello dear forum,

We are building a prefabricated house with a ventilation system. Today we had our blower door test, and the result was n50=1.13. The site manager said this is within the standard (max. 1.5). Regarding the conditions:
The building envelope is in place, but the skirt is still missing—that is, the material that is attached to the base slab.

What do you think about this value? As the homeowner, do I have the option to request an improvement in the result?

Thanks and best regards

I’m skeptical about these airtight houses sealed like Tupperware, which are then "opened up" again with ventilation systems or trickle vents in window frames. I wouldn’t be surprised if this building method ends up as just a passing trend in construction history.

Pure comedy.

The strange thing with these water closets probably won’t catch on either. Such a silly trend; a little walk outside in the yard has never harmed anyone. Just modern fancy nonsense.

At least the wood from the outdoor toilet felt nice and warm, unlike the ceramic with a plastic rim.

Unfortunately, I’ve already ordered it. A classic case of being persuaded by the sample advisor. :P

Now, everyone who has built without a controlled residential ventilation system is being crucified.

What a pity

No, it really solved one problem but created another.
Outdoor toilet removed – who still had one of those?
Water closet installed – too cold in winter without heating
So, added heating afterward

I believe that it is simply possible to achieve a comfortable indoor climate both with and without a mechanical ventilation system, without considering either option as extreme.

Ultimately, it depends on each individual's personal perception. That is what really matters when it comes to living, and as long as I feel comfortable with my own choice, I don't mind what others do for themselves. They are free to do whatever they feel is right for them, as long as they don’t try to impose their views on me.

This applies equally to all other areas of life.
