in the practice vignette I did the max duct coming out of the mech room is 32x24. so I assume I would leave 24" clear for the ducts and place them within that space even if they were smaller in the section cut, say 12x8 (I aligned the bottom of the ducts to the bottom of the clear space)
or should I consider that the max size of a duct coming into the room is 16x16 and only leave enough clear space for that?
hope this question makes sense!
basically: do I look for the largest duct size on a floor and then leave the clear space for a duct to accommodate that size? or do I base it off of the largest duct size coming into a room. are all the ceiling heights on a single floor level?
