Fewer openable windows with controlled residential ventilation

Hello,

Would you partially do without openable windows in a new building with controlled residential ventilation? More fixed elements or only tilt-and-turn instead of tilt? Manual ventilation is not desired anymore then.

The thought never really occurred to me during construction. We have all windows that can be opened. I still want to be able to open the window according to my preference. I would consider that completely separate from the [Kontrollierte-Wohnraumlüftung]. It doesn't really care if a window is open somewhere.

Once the aspects of cleaning/accessibility from the outside and ventilation during summer heat are clarified, you can safely do without a few window handles.

My thought on whether a window should be openable or not did not depend on the controlled residential ventilation, but rather on whether I needed a window to open there (e.g., simply to clean it) or not. Therefore, all the windows in our bathroom (upstairs) are openable because otherwise we wouldn’t be able to clean them – for ventilation or to have fresh air in the bathroom in summer, only two or three would have sufficed. Our kitchen window is fixed – but can be easily cleaned from the outside, and since I know I would never have opened it, we could use fixed glazing. etc.pp.

We also made almost all the windows openable because we hadn't really thought about it and didn't necessarily trust the [Kontrollierte-Wohnraumlüftung] that much. On the ground floor, we could have really saved some handles because you can reach them from outside for cleaning. Even after more than 2 years, we've never opened some windows.

Lol, luckily not even my husband thought of something like that... In summer we would probably have died at night without tilt windows. Top open, bottom open, let it blow through once... that doesn’t create any ventilation.
