I'm trying to figure out the best LEED version to use for an extension of an existing manufacturing building. It has not yet been determined if it will be open to the existing building (no walls between existing and new) or separate.
It is new build so I'm thinking new construction, but I wanted to confirm it is ok to certify only part of the whole manufacturing building (even if not separated by a wall).
Thanks for any assistance.

Check this carefully. It has been a challenge in shopping malls that were new builds "connected" to existing, non-certified, parts of the mall. The "open" was difficult to model without completing it on the entire mall, which was very expensive to do. There is also a question of LEED project boundary and showing what is certified and what is not. GBCI staff is always a great resource in addition to being the certifiers.

I have been successful applying LEED for New Construction to ONLY the addition of an existing factory. The LEED Project Boundary included just the addition and associated site work of the addition. Existing chillers/boilers served the addition and the energy modeler treated this as "purchased energy".
GBCI did not make a comment that the addition must be separated by a wall, since this project's addition was not separated by a wall from the existing.
GBCI may request documentation that confirms the owner will not represent the entire building (existing + addition) as LEED certified.
Good Luck!
