FAQs about MRc1.1 :

What building elements get included in this calculation and what can be excluded?

Should I base my calculations on plan or elevation?

How do you calculate the existing building structure reuse?

How do exterior elements, such as a covered dock, get counted? Would that be considered a slab or exterior hardscape and not part of the building?

NC-2009 MRc1.1:Building Reuse—Maintain Existing Walls, Floors and Roof

Reused area of column and beam

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?

Stanley, are you pursuing this credit under 2009 or v4? if you refer to the building reuse calculator for 2009, (click on "documentation toolkit" above) it says: "Exclude surface areas of structural supports like columns and beams from all the calculations, existing or reused."
