Dear all,
I'm wondering what certification approach I can propose for a poduction site consisting of 3 construction phases (like building extensions over different period of time):
phase 1 was built about 10 years ago and got LEED silver v2.2;
phase 2 was built about 5 years ago and the application for LEED silver v3 was stopped (because of lack of Fundamental Commissioning / assigned Commissioner Authority, lack of proper design documentation, lack of finalized energy model, undocumented design changes on site and lack of LEED construction recordings on site);
phase 3: going to be build, and it's again aiming LEED, but this certification would need to be for all phases.
So what is a approperiate approach, leed system and scheme for this situation? Phase 1&2 are together 55000 sqm and phase 3 will be 25000 sqm. All to be working as one single building with warehoises, storage and offices in it. I appreciate your quick feedback on this many thanks in advance.

My understanding for the narrative above:
The addition could pursue a New Construction certication. If this entire project (both existing and addition) would like to pursue certification then Existing Building may be the most applicable since the new construction floor area is less tha 40% of the total floor area.

link to the rating system selection guidance above that may also help.
Good Luck!
