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

[Pasha Korber-Gonzalez]

A couple of further questions then:


   - if you are doing a LEED (or other) compliance model (without design
   analysis) then do you build the proposed or baseline model first?
   - With eQuest 3.64 doesn't it create a baseline model file based on
   building your proposed model in eQuest first?  I thought that was the
   function/convenience of the compliance tool.   Of course the baseline model
   file needs to be checked and calibrated but the general intent was to
   streamline the creation of a baseline model file in response to the inputs
   for the proposed design.  Is this correct logic?
