EBOM-2009 EAc2.3: Existing Building Commissioning—Ongoing Commissioning
From reading these comments, it seems like any work done EAc2.1 MAY NOT count toward this credit. Activities that were done for EAc2.1 would have to be repeated, making EAc2.1 a baseline case...am I understading this correctly?
Thanks so much for your input!

I am confused by your question... Can you elaborate on what you are thinking. There is a difference between Option 1 and 2 in EAc2.1 that is referenced in a comment lower down on this page - is that what you are referring to?

Hi Matthew,
Sorry for any confusion...our team chose Cx in 2.1, and we were concerned that the work done for that credit (initial commissioning) would not count toward the 50% by cost threshold to earn EAc2.3...do have any thoughts on this?

ok i think i've got it now. From what i understand the point is to almost work backwards with these credits and definitely think of them holistically. Let me see if I can explain: if you choose this credit, then you agree to a plan and the implementation of at least half of that plan before you hit the submit button. If you perform the entire process (2.1), make changes as a result (2.2), and then commission those changes then you are demonstrating compliance with all 3. Since this credit requires the planning for these Cx activities as an ongoing process, you'll want to use that process in when proving compliance with 2.1 - if you don't however and for instance have an outside agency simply write up a report for 2.1, you may have trouble proving that 50% threshold. hopefully that helps!

Thanks so much for your reply, Matt - We have hired an outside Cx firm, and they will be providing a report for EAc2.1 and the plan for EAc2.3...if you have any examples of a filled-out plan or any tips for documenting EAc2.3, we would be so grateful! So glad to hear that our work for EAc2.1 will count toward compliance with this credit - good news! Thanks again -

EAc2.3 (Existing Building Commissioning - Ongoing Commissioning) requires at least half the scope of the first ongoing commissioning cycle to be completed prior to the LEED application submission date. If Option 1, Commissioning Process compliance path is pursued under EAc2.1, the retrocommissioning work completed under EAc2.1 and its associated costs may be used to account for a percentage of this ongoing commissioning cost when considering this initial retrocommissioning as part of the first two-year ongoing commissioning cycle. However, the team must complete 100% of the retrocommissioning activities in order to achieve EAc2.1. The 50% threshold is based on the entire ongoing commissioning cycle cost (max. two years).
