<div>Out of curiosity do you build your proposed model first or your baseline model first?</div>
<div> </div>

<div>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.</div>

<div>What's your approach?</div>
