I think that this has mostly been addressed via this topic:
@edpmay and @MaxMarschall ,
That’s a good suggestion and I just implemented it:
I was originally thinking that it was only hospitals and labs that needed to make use of the ACH property but, with the passive house use case, I think there’s enough to justify adding it. I also added the absolute flow_per_zone property (in m3/s) on the “HB Apply Absolute Loads” component and I implemented it in a manner that overrides all of the other ventilation inputs (vent_per_floor, vent_per_person, vent_ach)…
The only thing that wasn’t really addressed there is the ability to get net volume instead of gross volume. I think this is something that I would add if I addressed this issue:

This should be pretty straightforward given that all of the opaque construction … objects have a thickness property. So all that we would have to do is compute the Room floor area, then take each floor segment that is adjacent to a wall and:
- If it's a segment next to an exterior wall, subtract the `segment_length * construction_thickness`
- If its a segment next to an interior walls, subtract the `segment_length * (construction_thickness / 2)`
It would probably be faster/easier to compute this in dragonfly where we know all rooms are extruded floor plates but I think we can still do it in honeybee with some extra checking of adjacent vertices across a Room.
So, if this is something that you think you’ll want sooner than later, than

that issue and I’ll prioritize it.
