We typically use C407 in 2015 IECC, unless a project can't meet the 15%
savings threshold, then we use ASHRAE 90.1-2013.  Under ASHRAE 90.1-2013
projects don't show any savings, but they have to do end-use monitoring and
receptacle control.  There are other differences, but design teams would
rather stick with what they know and that's the I-codes.
