It's not obvious to me why this doesn't make sense.

What "Replacing the air fully" equates to in terms of volume is already a factor of the size of the room/house.

You might want to know what volume of air that actually was to understand energy usage, but gp was talking about air quality, not energy efficiency.

Exactly. If one person lives in a castle, do we need to replace all the air every hour? Certainly not. If we are talking about a person in a 5sqm room (for sleeping) then replacing all air every hour won't be sufficient.

There are more factors besides the number of people and the air volume, but I really didn't want to go into so much detail.
