For those of you who do 2015 IECC compliance modeling, do you use the
IECC?s Total Building Performance method or do you use ASHRAE 90.1-2013
Energy Cost Budget Method instead? Main reasons you use one or the other?

The State of Hawaii is considering holding training on the performance
method for local designers, and I'm curious about standard practice
elsewhere.
