In MR c1.1, how to calculate the column and beam area? I acknowledged that the reused area of supporting elements should be included into reused-wall area calculation, but how LEED actually decide the area of a column if all surface area of it is reused? e.g. the whole column area or only the area attached to the wall? Besides, in LEED V4, the reference guide says "Calculate the surface area of these supporting elements as equal to surface area of the wall.", do you think it is appropriate to count column area the same as wall area?
