Schools-2009 EAp2: Minimum Energy Performance
There are currently two ASHRAE AEDG versions available, one if for 30% savings over ASHRAE 90.1-1999 minimum and the other is for 50% savings over ASHRAE 90.1-2004 minimum. LEED 2009 for schools does not specify which AEDG should be used under EAp2 - Option 2. Does this mean that either one can be used?

The one referenced for LEED 2009 was the 30% one published in 2008.

Marcus,
I don't see it in the LEED 2009 BD+C Reference Guide, EAp2, Summary of Reference Standards, Page 242. Is this clearly addressed by USGBC in some other document?

Just in the document of logic.
When LEED 2009 came out the only version available was the 30% one which was published in 2008. The 50% one was published in 2011 so it could not be in LEED 2009. When the Reference Guide was published the 50% one was not even out. LEED does not adopt new versions of standards automatically. The 50% one is referenced in LEED v4.
