Hello everyone,
we are currently planning our solid-built house without insulation. However, we are unsure whether to install a central ventilation system. The general opinion, for example in forums, is that such a system should definitely be included in a new build. Reasons given are comfort, continuous air circulation, and so on—well known points. It is also understood that it may not be energy-efficient.
BUT: I have already spoken to one or two architects who say: definitely build without it. Their reason is that everything works fine initially, but after 5 to 6 years hygienic problems can occur despite maintenance. Based on their experience, most installed systems are eventually turned off and no longer used. Some doctors also confirm this and would not install such systems themselves. Their argument is: for prefabricated houses, yes, because necessary. For solid-built houses without insulation, no.
I am torn. On one hand, I want to stay up to date with what makes sense; on the other hand, I don’t want to install something that will be switched off after a few years anyway.
I am completely unsure now whether to choose it or not and hope to get some opinions from you!
Thank you very much in advance!

This part appears to be a ventilation system with additional heating coils integrated into the supply air system, which is used to heat the house. Warm air is blown into the rooms.This system was also explained to us yesterday during a presentation, and I raised the issue regarding cleaning and the contamination mentioned earlier. Unfortunately, no clear statements could be made about this yet. The idea is good, but if cleaning cannot be guaranteed and the system might have to be shut down after 5-6 years, hmm...

Doc.Schnaggls12 Feb 2015 17:09Last week, we had the technical briefing for our heating system with controlled residential ventilation.
All supply and exhaust air vents are equipped with filter media. Likewise, there are filters at the outdoor intake tower and again inside the ventilation unit itself for both supply and exhaust air.
Therefore, it is not entirely clear to me how these well-protected, filtered ducts on all sides could develop into a hygiene problem if the filters are regularly replaced.
A good friend of mine, who services such systems in single-family homes as well as large commercial buildings, also dismisses this concern. According to him, as long as the filters are replaced regularly, no problems arise.
Otherwise, all ventilated office buildings from the past 20 years would have to be closed due to an acute "contagion risk"...

That is, of course, also a point of view. Opinions still vary quite a bit on this, as the saying goes.

Sebastian7913 Feb 2015 07:34Why do you have filters in the supply air vents? That is rather unusual...
Otherwise, it is definitely recommended to use an intake filter in addition to the device filters, as well as exhaust air filters.

Doc.Schnaggls13 Feb 2015 08:32@Lexmaul79: As a layperson, I don’t feel qualified to judge whether this is standard practice or not. At least in our development, the filters I described are always included as standard.
According to the technician, the filters in the supply air vents are mainly meant to trap fine dust.
The technician who gave us the briefing installed all the filters together with us, so we would know exactly where to access them when it’s time to replace the filter media.
Best regards,
Dirk
