You mean retrofitting a controlled residential ventilation system in an old building? In the case of a major renovation, it's basically no different than in a new building, if you disregard that you can't embed pipes in the concrete ceiling (which I don't support anyway). You should take enough time and ideally keep the system in mind from the very beginning when planning the future floor plan (just as the bathroom should ideally be planned close to the supply lines or the heating). In our case, on the ground floor we get by with a 40cm deep partition wall (in the lower third a distributor, in the upper 2/3 a bookshelf) and about 1.5m² of suspended ceiling in the hallway and guest bathroom (also used for lighting). On the upper floor, 2 shafts of about 25x25 in the room corners were necessary. We also complement these with a built-in shelf so they don’t stand out. Otherwise, in our case, 4 core drillings of 300mm through the exterior basement wall and ceiling and some chiseling work are needed. Apart from that, the installation is nothing special. Underfloor heating is identical to new construction. You just might have to remove old screed beforehand. But that’s absolutely no problem and is even fun with the right machine (Tim Taylor grunt).
