We are currently planning the controlled residential ventilation. On the upper floor, our builder is only installing wall outlets for the controlled residential ventilation and is somewhat reluctant to place openings in the ceiling. He justifies this by saying that each ceiling opening would mean piercing the vapor barrier twice, and that each angle in the ceiling is supposed to cause higher noise levels. Is that true? We actually prefer ceiling outlets since the wall inlets would otherwise have to be placed on the only wall where a wardrobe could be set up. The attic is being converted for us, meaning the ceiling is not part of the thermal envelope to the outside. Is the vapor barrier still important in that case?
Furthermore, the wall inlets are generally planned quite close to the door (partly behind the door). Is that reasonable? When the bathroom is ventilated by extraction, fresh air seems to immediately leave the room towards the bathroom.
