We are building a considerable extension with new production lines to an existing manufacturing plant built in 1984, that has no LEED certification. The client wants to apply for a LEED certification for the entire plant, the existing building, as well as the extension, which is directly attached to the existing plant.
No major renovation is planned for the existing building and production will be ongoing during construction of the new extension.
GFA area ratio for existing/new construction around 55/45 Please advise on the following:
1) Is it possible to apply for one certification for the plant (new building & extension)?
1.1) If the GFA percentage of new construction is just around 40% are we still allowed to go for LEED NC by including the existing building?
1.2) If we are free to choose between EB and NC: I am not familiar with LEED EB: can you give me a direction what is your experience which rating system will be more appropriate to follow in this case?
1.3) Is it possible to submit the application for LEED EB for the entire building at the end of extension construction?
2) Or do we have to apply for 2 separate certifications (LEED EB for existing) and (LEED NC for extension)?
Can anybody give a recommendation on that, please?

NC and EBOM are whole building systems, so if your facility is one whole building, then one of those systems should be used (or potentially, do NC for the whole building, and then follow a couple years later with EBOM for the whole building).Because of the percentages involved here you have some discretion between NC and EBOM, in my opinion. There is no right answer. If you read through the EBOM guidance on this website you'll get some sense for what's involved. Ultimately I think buildings should be using EBOM to track and improve ongoing performance, as that's what really matters. But if NC is a good fit to guide the major work that's happening here, then start with NC and consider EBOM in the future.

Another test you can do is review MPR 2 from the NC program. It may answer your question on the addition.
