Is this LEED-CI, or NC/CS/etc? Modeling for LEED-CI under v4 is an
entirely different animal. NC/CS not as much so.
90.1-2010 requires auto-receptacle control, daylight harvesting for
zones with > 250 SF of window area, etc. Lots of control changes like
that, but nothing that would make you redo the basic structure of an
NC/CS model.

Subject: [Bldg-sim] LEED 2009 vs LEED V4
All,
I am trying to determine the impact of switching an already built energy
model which follows ASHRAE 90.1 2007 (LEED 2009) to ASHRAE 90.1 2010
(LEED V4).
I know that at face value, this will likely negatively impact the
percent energy cost savings that I have been able to show. The LEED V4
point-system is different, so it might not impact the savings quite so
adversely.
Any advice or quick thoughts?
Much appreciated,
