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,
