Fewer openable windows with controlled residential ventilation

I would use fixed glazing for the light strips (if you have any). Otherwise, everything should be openable, yes, if only for cleaning purposes.

We made the mistake of installing 2 fixed floor-to-ceiling elements in the living/dining room.

All our glass surfaces (except the fixed element next to the front door in the north) have roller shutters.

And the two fixed elements are really dirty because of all the construction dust in the new development area. And on one of them, a few insects once sat on it when the shutter was rolled up. And now they are stuck on the inside. That means you sit at the dining table in the evening and can comfortably look at the crushed insect carcasses...

Fixed element without roller shutter: yes
with roller shutter: never again...

You could take the roller shutter slats out of the box at the top and clean them. Just a tip.

A controlled residential ventilation system does not replace airing, especially not in the first year after moving in. I would always design all windows to be openable.

I have one single window permanently glazed (for safety reasons). I would no longer want it that way; something that can be opened is easier to handle.

We made the mistake of installing 2 floor-to-ceiling fixed panes in the living/dining room.

All our glass surfaces (except the fixed pane next to the front door in the north) have roller shutters.

And the two fixed panes are really dirty because of all the construction dirt in the new development area. And on one of them a few insects once sat on it when it was rolled up. And now they are stuck on the inside. That means you sit at the dining table during dinner and can comfortably look at the crushed insect carcasses...

Fixed pane without roller shutter: yes
with roller shutter: never again...

There are aids with magnets that allow you to clean the roller shutters from both inside and outside at the same time
