Hello everyone,
I’m writing here as a tenant, not as the property owner.
My wife and I will be moving into a passive house with a controlled ventilation system in September.
One of the supply air vents is located at foot level on a wall where I would like to place a cabinet.
My question: Is it possible to install a built-in cabinet in front of such an air outlet?
I would leave the part of the cabinet directly affected by the vent open at the back and top.
Would that be sufficient? The cabinet does not reach the ceiling. There is about 10 cm (4 inches) of space above it.
Thank you very much for your answers.
A brief note about the apartment: 160 m² (1,722 sq ft)
The living area where the cabinet is to be placed is 70 m² (753 sq ft).
Best regards,
Marko

And the heating season is all well and good, but for half the year there is no heating. Also, the blown-in air doesn’t warm up immediately and then rises.
By the way, I’m not referring to objects, but to liquids...
Every solution has its own quirks, but embedding in the concrete slab requires the least effort, and the outlets are definitely located where they make physical sense.
Additionally, you don’t block any walls – you remain completely free in your room layout.

So if you are quick enough, and with today’s precast concrete slabs, is it possible to lay round pipes inside?You need to coordinate this with the structural engineer beforehand and provide them with a precise installation plan.

Bieber08158 Sep 2016 11:08Whether the pipes are installed in or on the ceiling does not necessarily relate to the location of the outlets. These can be planned independently.
In our case — two levels — it is more advantageous to run the pipes on or inside the ceiling and then supply fresh air directly at floor level. If I wanted to bring it from the ceiling, I would first have to get there, which would involve significantly more effort. In other setups, the situation might be different ... Both solutions exist and are feasible, so it ultimately depends on the individual case to determine what works best and is preferred.

What type of screed insulation do you have here? It must be quite thick. I see some round pipes crossing other cables as well.
Is that insulation supposed to be 90mm (3.5 inches) thick?
By the way, what are those silver cables? Electrical wiring? Heating pipes?
Best regards,
Andreas

Bieber08158 Sep 2016 15:13What is the outer diameter of the green pipe? How high is the highest point in picture 2 (intersection of the ventilation pipe with the water pipe)? (And where is the electrical installation ?)
