Out of curiosity do you build your proposed model first or your baseline
model first?

I build my proposed model first. This is the way that I was taught and the
way I learned that makes sense to me in terms of "backing-off" the
performance values to that equal of the baseline values. Or in the case of
different types of HVAC systems I prefer to build the proposed model first
and then do a "save as" to a baseline file to make all the appropriate
baseline input adjustments. This just seems most efficient for my modeling
approach.

What's your approach?
