Or onto the raw floor and into the walls. There are various possibilities. Suspending the ceiling is not necessarily the cheapest but relatively simple to execute.
We are also getting a controlled residential ventilation system in our townhouse. And we also have a cold roof...
I’m curious to see how it will be solved for us...
That would go into the intermediate ceiling – so into the filigree ceiling – and then the concrete goes on top or something like that.. in detail, others here can probably explain that better.
Today we visited a company that installs Zehnder systems at a reasonable price. They would now install it with flat ducts in the floor at our place... now we just have to make sure that the general contractor and the company coordinate with each other, and then we will still get our desired ventilation system...
Since we are facing similar decisions, a fundamental question. Why do you decide against a decentralized ventilation system? According to the paper, these are now so efficient (85-95% heat recovery) and very quiet 20-25db.
We would therefore have to increase the ceiling height
I seem to recall that the lintels were too "high" for you - from this necessity a virtue could be made and the ducts discreetly boxed in drywall as done in commercial kitchen construction.
