[Equest-users] Baseline or Proposed? Chicken or the egg?

[Paul Diglio]

Pasha:

I always start with the baseline model because I am usually hired to provide 
design suggestions.  By modeling the baseline first I become familiar with the 
90.1 requirements for the type of building and systems we are working on and I 
can make suggestions that will increase the efficiency of the facility above and 
beyond the 90.1 standard.

For example, if my total exhaust air for a zone is less than 5,000 CFM, 90.1 
does not require exhaust energy recovery, but by implementing this option in the 
proposed model we can achieve a greater reduction compared to the 90.1 baseline.

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?
