Regarding MPR2, the "Supplemental Guidance to the Minimum Program Requirements (Revision 2)", on page17 Article III.1) is titled "VERTICALLY ATTACHED, LEED-EB: O&M, AND MAJOR RENOVATION PROJECTS". My reading of Article III.1) is that it does NOT apply to LEED NC projects. Is this correct? My client is considering certification of a horizontal addition to an existing non-LEED certified building and it's not clear to me whether this Article III.1) applies. The client will own and manage both the original building and the addition.

Brian,
I've seen Article III. 1) applied to an EB: O&M project where the lower floors were a commercial office building seeking certification and the upper floors were residential condo apartments. The lower floors (the office building) had separate elevators, separate ground floor lobby, a different name and address, and separate mechanical systems & meters from the condo apartments and thus was really two separate "buildings" stacked on top of each other, aka "vertically separated." The condo HOA was also separate ownership from the office building. These conditions allowed the floors of commercial office to pursue LEED EB as it's own "building" and ignore all the condo areas and systems.
I've seen the USGBC rule that NC was not appropriate for a project that was a fairly large renovation of and addition (below grade) to an academic building. They required the addition to follow LEED-CI even though the bulk of the space being certified was "new construction." I believe the main issues were that the addition shared some of the main building systems, ownership was the same, and the addition was less than 60% of the building entirety.
However, I have seen NC allowed for a building addition to a museum in which the main building was not LEED certified. The wing had it's own name; it's own HVAC systems, and distinct access point where the plaque for the new wing was displayed. This was also a pre-2009 project, so that may have made it simpler...
For your project, if it's horizontally attached it sounds as though CI may be a better fit. Make sense?

Thank you David. Actually my project sounds more like the museum you describe in your third paragraph.
