Hi!

What areas/rooms should we consider inside an appartment for the calculation of naturally ventilated spaces? For example, the master bedroom has a dressing room and a bathroom, should we consider all these spaces?
What about circulation? Usually, it doesn't have any openings to the exterior, but doors to the other rooms. What about the kitchen, laundry rooms and the other bathrooms?
And the doors between two rooms can be considered as an "unobstructed opening"?

Thanks!
