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

When I think of the gargoyles on late medieval manor houses that spout water from the roof, I immediately get an idea: Each downspout could have its own custom-made gargoyle head made of tinplate, copper, or ceramic. Maybe it even breathes steam in cold weather.
That could really be something...

But definitely add the stone front garden in Asian style... 😉

I am also considering a decentralized system. A central ventilation system is definitely not an option for us either. What do you think about the corner zero units? Their Xenon fans are definitely high-tech, but could serious issues arise with insulation and plastering if they are installed in the window reveal?

Where does this fundamental rejection of central ventilation systems come from, which apparently many homeowners share? I would really be interested in the objective reasons behind it.

Therefore, when building the new house, I decided without much hesitation to use the same system again, since I am working with the same company that constructed the apartments.

Someone really understood my stone mantra 🙂

I’m curious about that as well. I know some general contractors avoid it because it’s somewhat more complex during the construction phase, especially regarding planning. It’s also a bit more expensive, which doesn’t help budget providers when price is compared. Fortunately, the old myth about dirty ducts is now rarely heard anymore, thankfully relegated to the past.

Objectively, I don’t know of any disadvantages or arguments against it.

Apart from the price argument, I feel the same—I don’t know of any drawbacks. Our system has been running completely trouble-free and absolutely silently since 10/2018. Only inside the utility room itself can you hear the controlled ventilation system, and if you listen closely in the guest bathroom directly above the utility room, which is the shortest path to the ventilation unit, you might just barely hear a very faint noise when the device is running. Visually, the central solution is unbeatable anyway.
