ᐅ Decentralized ventilation system with minimal visibility on the exterior facade

Hello dear building forum,
We are constructing a 210 sqm (2,260 sq ft) single-family house to KfW 55 standard and want a decentralized ventilation system. (We have deliberately decided against a central ventilation system, but this is not the topic here.)
I am looking for a system that is discreet on the exterior of the house, for example, integrated into the window reveals. We do not want to have fans visible on the facade in every room.
Who has experience and can recommend something? I look forward to the exchange. Best regards

Quieter, but not by much.
You can almost invisibly install it into the window reveal. Outside noise is only an issue in very loud environments.
Same goes for decentralized systems.
The ventilation capacity is calculated correctly for both options and is identical.
... over 90% for decentralized systems.
Nonsense!Of course, a central system is 100 times quieter than a decentralized one. Why do you think that is nonsense???N

Isokrates17 Apr 2021 10:10I currently live in a KFW 55 condominium built in 2016/2017 with a decentralized ventilation system from Aereco, which the company installs as standard. I hardly notice the system in terms of noise, and in my experience, the air quality is always very good.
Therefore, for my new build, I decided without much hesitation to use the same system again, since I am working with the same company that constructed the apartments.
Visually, I hardly notice the units, but of course, that is always subjective.
In my case, I saw no reason to upgrade to a central system, as, like I mentioned above, I have not experienced any negative aspects so far.

askforafriend17 Apr 2021 10:14What I always find missing in such comparisons is that the equipment plays a crucial role. In show homes, I was clearly able to hear both the central and decentralized ventilation systems, and vice versa.
What I mean is: there is definitely a difference in the quality and performance of the devices.

I can imagine the hole becoming a design feature with appropriate decoration. Thinking of the gargoyles on late medieval manor houses that spout water from the roof, I already have an idea: Each hole could have its own individually crafted dragon head made of tinplate, copper, or ceramic. Maybe it would even make a wonderful puffing sound in cold weather.

From a purely technical perspective, it is obviously much smarter to house the mechanics and fan(s) in an enclosed space and decouple them using silencers, rather than installing a small, annoying buzzing fan directly into an open wall opening in a decentralized manner. It’s also not rocket science that this approach is more efficient and powerful than having eight individual small fans due to limited installation space.
Since a single-family house usually does not require a full ventilation system, a compromise would be to equip the bathrooms with one decentralized unit each, and if you find a very quiet unit, also the bedroom. These are the rooms where users benefit the most.
If you have the budget, install a central system and enjoy the many advantages 🙂. Everything said.
