Ceiling suddenly too small for controlled residential ventilation!

The height should actually be around 2.60, but if the ceiling has to be thicker because of the controlled residential ventilation... Let's see what the general contractor has to say tomorrow! The wardrobe fits perfectly in the bedroom!

I can't really imagine the floor now... Just a hole with a grid in the floor? A wall would be nicer there.

Do you think a controlled residential ventilation system makes sense there? Or rather a single-room ventilation and this window rebate ventilation? It really looks like the house isn't designed for a controlled residential ventilation system!

You have to decide for yourself. Personally, I would probably take a grid in the floor if necessary before having no controlled residential ventilation at all, or possibly ventilate the most important rooms decentrally (listen and choose yourself). It is possible without controlled residential ventilation. But then with gas you need solar thermal again, which brings no comfort, that would be annoying.

If necessary, there is also active ventilation via valves without heat recovery with central exhaust, but this is basically no longer installed nowadays - possibly still better than uncontrolled ventilation through window rebates.

Where? And what size? A 3-meter wardrobe has to fit in the bedroom, anything less won't do. Two meters for 2 people, one for the family laundry.

But you do know that with the floor construction you end up somewhere between 2.43m and 2.48m top edge of finished floor depending on the thickness of the insulation!?

So in our case, the [Kontrollierte-Wohnraumlüftung] is also mounted on the ceiling - above the heat pump. Works well! The room is packed full of technology but it works! Upstairs there are two rooms with floor grilles. Stylish, simple stainless steel grilles. The rooms where drywall partitions were installed have ventilation grilles in the walls again. Before I would do without a [Kontrollierte-Wohnraumlüftung], I would definitely solve it this way! I was a bit skeptical at first, but it is really a total gain in comfort!

Would the space be sufficient if you include the WC downstairs next to the technical room?



Or has the base slab already been poured and is everything too late?

You are all now trying to square the circle. It is tight. Think small and take a gas boiler and [Solar Thermie Warmwasser]. That is the smallest and works wonderfully. For the money saved, [Fensterffalzlüfter] and [Abluftwilly] in the bathrooms. If there is still something left, screw a nice awning onto the terrace.
