NC-v4 EAc2:Optimize energy performance

CS Alternative Compliance Path

Will the LEED CS 2009 Alternative Compliance Path continue through to LEED version 4? There is a 2009 calculator that CS projects use to determine revised points thresholds based on Owner-Influenced energy percentage (dated August 30, 2011). Will there be an updated calculator for LEED version 4?

I would think so as the primary concept remains the same. The thresholds have changed so a new one needs to be prepared. I have not yet seen a new one posted on USGBC's web site. I would contact USGBC/GBCI directly and ask. The best way is foten through the Contact link on gbci.org.

Hi there, any updates on this?

I think I heard that it was discontinued for v4 projects but I am not sure where or when I heard it or if it is in writing anywhere.

In version 4, you'll notice that CS has a different point scale than NC. The logic for this is to account for the limited influence the landlord has in a CS project. So I do not expect an ACP will be created for v4.

Thank you. I got an official answer from USGBC saying it is not applicable to CS v4.
