Planning single-family house with ventilation or without

Hello,

the construction of my single-family house is supposed to start in March. Now I have a question. The architect says central ventilation is too expensive, better to just open the window from time to time. My carpool partner used to be a heating engineer and says definitely to install it in a new building. What do you say about that, install ventilation or not? A buddy tells me that if I install ventilation, I should have the intake pipes laid under the floor slab right away. What do you say about that?

With. Whether central, decentralized, in the attic or under the floor slab is probably a matter of personal preference. Without it, it is stuffy - window ventilation no longer really works even in buildings from 1995.

The architect exceeds the mentioned limit with ventilation? Also a method to stay within the limit... Simply remove [zeitgemäße Technik] ;)

How much do the ventilation pipes and stuff cost me? Would you put the intake under the slab?

It depends ...

There are many posts on the topic of controlled residential ventilation pros/cons in the forum; just read up on it. Not every user has the desire and patience to answer the same questions over and over; that's why we archive the threads for newbies ;)

Happy New Year!

Matze, I know you :-)
