The text in the LEED-NC 2.2 Reference Guide for EA Credit 1 (page 173)
states, "Demonstrate a percentage of improvement in the proposed
building performance rating compared to the baseline building
performance rating per ASHRAE/IESNA Standard 90.1-2004 (without
amendments)..."
Sincerely,
Keith Swartz, PE, LEED(r) AP
Also refer to the memo posted on USGBC web site which allows the use of
addenda to 90.1-2004. See link below.

The location of the document with this important modification may seem simple from the link. However the location is not at all obvious on the USGBC's "improved" website. On the LEED/LEED Rating Systems/LEED NC page, there is a link to a summary of our dear rating system, some posted errata, multi-building/campus guidelines, and a link to "Green Source Mag." A user would be forgiven if they thought this was a complete accounting of the system.
BUT, separately there is a LEED/LEED Resources (different than "Resources")/LEED Reference Documents page, where this memo resides along with the errata again. Nothing on the Rating Systems page indicates or links to this other page where this and some other important guidelines for EAc1 are located. This page should be linked to the rating systems page(s).
The CIR page, obscurely located under "Project Certification," should also be linked to the rating system summary page(s). And the CIRs should be viewable by the public not just us members.
Happy Monday

Occasionally questions surface in this listserv relating to getting the Revit (3d BIM model) over to IES for energy analysis. See http://greenbim.blogspot.com/2008/01/revit-archirtecture-to-ies-workflow.html for recent post on the subject. Important to note that this post demonstrates Revit Architecture to IES through plug-in tools. If you have Revit MEP, it is different.
