Controlled residential ventilation planning/design, experiences

Don't be angry with me, but the points you demand (let's rather say address) have, in my opinion, nothing to do with my actually asked questions. I think my questions were clearly stated and all side issues do not help with problem solving either. If forum colleagues were here who could help me, a correspondingly fruitful dialogue would arise on its own.

What do you actually think, why someone, despite explicitly not having specific product knowledge of your question, makes the effort to share with you his 20k posts worth of experience with this forum? - because I would have no clue what is a side issue when and when there is a causal connection between basics and disappointed expectation of answers??? And I also don't understand whether the special experts happen to find their way into your thread? Netiquette six minus, sit down!
