We are defining a LEED boundary for our 2009-NC project. This is an arena project on a campus with major additions at the perimeter of the arena. The arena and the new addtions define construction for the certificaiton. It is a (3) story facility. There is an existing 2-story building (separate address and building name) connected that is not included as part of the certification. The LEED boundary would be simple as we can use the disturbed area of the site excluding the existing connected building. My question is that on the third level, part of the new addition to the Arena extends over the existing building that is not part of the certification. How do we document the LEED boundary. Can we provide a floor by floor LEED boundary or explanation that excludes the existing building and then a separate LEED boundary that includes the third floor construction over that existing building?

Julie, based on the LEED Minimum Program Requirements supplemental guidance document and the requirements about including a building in its entirety, I don't see how you can exclude the existing arena. However, GBCI has become more accommodating about these situations in the last year, so I may be missing something there.On the boundary question, I would envision the boundary as being in three dimensions, going over the existing building, and make sure that you explain what's going on when possible.

Thanks Tristan - I am not sure my inital explanation was clear. We are including the existing Arena as part of the LEED boundary - it is the separate 2-story building adjacent that we are not including. This existing building is named separately, does not share any HVAC services, is metered completely separate and only connects via a single tunnel. I have contacted GBCI on this question as well - I will post once we have an answer. I plan to show the boundary via a building seciton as well as a site plan.
