Hello everyone,
we are finally living in our KFW40 house, which has really gone through ups and downs.
Basically, only "minor issues" remain, although almost all were unnecessary and already known.
DEKRA has inspected the house, and we’re still living in what is basically a 4/5 construction site.
Anyway, I recently happened to notice that the ventilation is missing in the dressing room in the attic.
Usually, we have ventilation in the ceiling, mostly near the edges of the rooms, in ALL nine rooms.
Even the basement has ventilation, except for a very small storage room on the upper floor.
I only noticed this because it was very warm and musty in the still unfurnished dressing room.
Today, the site manager and the "climate technician" (?) came by to have a look.
Of course, the blame is being shifted, and there’s no talk of "it was forgotten."
It was built as it was in the plan. Now the plan is being requested to see if it includes ventilation there.
If it is included, the matter is clear. If not, it should be clear as well, right?
I think this will definitely end in a dispute, but what is the real technical and legal situation?
Do I have to accept that ventilation is missing in such an important room where all our textiles are stored?
And how can this be "easily" solved? Suspended ceiling? Or a breakthrough to the next-door bathroom?
Thanks for your opinions and advice.

Of course, mistakes happen, but our small list of errors is getting longer day by day.
These aren’t even extreme issues. Basically, just “basic” things that every apprentice should know.
Anyway, that doesn’t really matter here, the fact is that the ventilation was obviously forgotten there. Over the past few years, especially through direct experience here, I’ve seen quite a bit. And 99% of the time, these basics are the things that get forgotten, which really upsets the builder/homeowner. Then there’s gossip about how this simply can’t happen and what a poor-quality company it must be. In my own job, it’s also unusual for so many things to go wrong, but somehow on construction sites it seems to be normal.

Even if you try to justify the clothing issue, what about meeting the KFW requirements?
I think for KFW40 it’s definitely important that every room is connected to the ventilation system. I don’t know the exact details either, but I wouldn’t expect one outlet to make such a big difference. If it does, then either corrections need to be made or the financial damage has to be covered by the builder/developer.

What could a decentralized ventilation system look like? That would involve drilling a hole in the wall and installing a suitable device. A quick search online shows plenty of examples... In the end, you usually just see a 15cm x 15cm (6 inches x 6 inches) plastic cover.

I don’t want to go into detail about how the house construction went and is still ongoing. Nobody asked for that.

Plans were often changed without informing us, and You must have the original plan...

I think for KFW40 standard it is quite important that every room is ventilated through a network. Not really. What exactly are you afraid might happen?
The bank will refuse your KFW loan and take the house and property,
or
You will suddenly use twice as much energy as planned,
or
You will suffocate because the mechanical ventilation system provides no fresh air, sorry, only exhaust air.

Even if you sugarcoat the clothing issue now, what about meeting the KFW requirements? What I can actually understand: it can get smelly. Not everything stored is freshly washed. But as I said before: decentralized ventilation. You can worry as much as you want now. There is a solution: decentralized ventilation.
From the overall picture of your description (almost identical house in the second construction phase and so on), I conclude that this is indeed about a property developer ...
... therefore, I suspect the expert organization is overseeing the construction as a quality inspector commissioned by the property developer – however, I don’t see how the terms “inspected” and “4/5 construction site” go together; they sound contradictory to me.
As the buyer, you decide WHAT the developer builds for you. Two contractual documents or attachments – namely the building and service description and the plans – should say the same thing or at least not contradict each other. If the service description specifies “central controlled residential ventilation, but only in living areas,” then the walk-in closet is excluded. If both the service description and the plans say “central controlled residential ventilation, including storage rooms,” it needs to be clarified whether the connection for that room was omitted or only the outlet on the duct – and in the first case, the proper solution would be to retrofit decentralized controlled ventilation in the walk-in closet (which is not a big issue; who really needs heat recovery in the closet). Also, is there no door under- or over-ventilation to the walk-in closet, and are the supply and exhaust outlets in the bedroom too far to serve the walk-in closet?
In general, when dealing with a property developer, even more than with a general contractor, the rule is: “what is not written down is at sea / in God’s hands.”

But who decides whether a ventilation system is installed there or not?

In the plan I approved, no ventilation systems are shown at all.
