I'm going to furnish an attic that is only insulated. After reading on the forum and starting a few threads, I have a pretty good idea of how to set up interior walls, walls against the knee wall, screwing the ceiling, etc.
I realized that I haven't planned for any ventilation. I know nothing about that.
Do I need to create some kind of ventilation, or can I just screw up my walls upstairs without having to consider it?

Then it's an exhaust air heat pump. You should install supply air vents in the rooms and exhaust air vents in the bathroom and possibly in the closet or other similar space.
Hm ok. As I said, I don't know anything about this stuff. I will have an open ceiling up to the roof ridge, so I can't put anything in the ceiling; it has to be in the interior walls.Schlbuditz said:
Do you have any suggestions for what I should install? Would you kindly link to the products?
Is some sort of ventilation thing in the walls enough, or does it require a ventilation duct with pipes and the like?
Supply air can be managed with vents, for example, in/by windows/radiators that draw air from outside. The exhaust air is taken from the bathroom/kitchen and should normally be connected via spiral ducts to your exhaust air heat pump. These installations should then be adjusted to function well.
The idea with the ventilation in the house is to supply fresh/clean air to spaces where you spend time/sleep, like bedrooms/living rooms. Then remove dirty air from rooms where it becomes contaminated, like the kitchen/bathroom/laundry room. In this way, the air moves from clean areas to dirtier ones to prevent smells from spreading from the kitchen/toilet. The ventilation should also be balanced to create a certain underpressure in the house to prevent warm moist air from being pushed out into the building's roof and walls.
To meet certain requirements, the air in the house should be exchanged with a certain amount all the time. (I seem to recall that it's 0.35 liters per second per square meter).
Hope this provided some insight into house ventilation. There's quite a bit described online about how it works. Search for, for example, villa and ventilation.

Read texts www.svenskventilation.se or www.luftbutiken.se which have a ventskola to gain some basic knowledge about villa ventilation.
You probably need to plan a bit in advance.
Since the exhaust air heat pump is located on the lower floor, you need to figure out how the exhaust air from the upstairs bathroom will be routed to the heat pump.
For example, you may need to make a wall thicker/wider so that a ventilation duct can fit there. Alternatively, the duct might be routed through the attic space.
But, as mentioned, plan in advance. If you furnish the upper floor according to Hjältevadshus's suggestion, they probably have a ready-made solution. Check with them!
