Has there been an equivalency established for LEED v4 projects that use ASHRAE 90.1-2013-Appendix G as reference standard (as there was for LEED 2009 projects that used ASHRAE 90.1-2010-Appendix G ILO ASHRAE 90.1-2007)?

Great Post Gail!
We are hoping a LEED Interpretation similar to 10421 will show up in LEED v4 or 4.1. I have spoken with USGBC on this issue and am optimistic they will find a method to incorporate 90.1-2013, however they have not committed to a response a this time.
Marcus, what insight are you able to provide?

I am sure it will be on the EA TAG's agenda at some point. Not sure when.

Hi Marcus,
Has there been anymore discussion about this? I'm aware of the Pilot Credit, but is there a different option that wouldn't require use of 90.1-2013 addenda?

To David's comment, the TAG reviewed this last January for v4.1. For compliance with EAp2 and EAc2 in v4.1 see this LEED Interpretation that resulted: https://www.usgbc.org/leedaddenda/10488 (note: it appears you have to scroll wayyyy down to see the applicable points tables in the two different browsers I just tried.)
