Proposed & Baseline

As far as I can tell, I'll have to submit four models for LEED
1. Proposed building
2. Baseline building not rotated
3. Baseline building rotated 90 degrees clockwise
4 Baseline building rotated 180 degrees
5. Baseline building rotated 90 degrees counter-clockwise

Thusfar, I have composed only my proposed building model. (It required
some changes, but is nearly done.) However, I have not composed any
baseline model. My questions are the following (to which I have found no
answer in online resources):

1. Should I approach this by creating 5 separate projects, simulating
them, and reporting the results to USGBC via 5 distinct reports with a
supplementary hand-typed summary of the % energy savings, etc. of the
proposed model?
2. Should I somehow get eQuest to include these 5 different versions in
one single project?
3. Alternatively, should I have eQuest include the four baseline versions
in one project and somehow get it to average the results, which I will then
contrast with the proposed model's results in a hand-typed summary?

If question #2 or #3 are answered "yes", then how do I get eQuest, at
this point, to manage multiple model versions in a single project?

If question #3 is answered "yes", then how do I get eQuest to average
the results of the four baseline orientations?

Also, in general, what reports are expected by the USGBC for LEED
evaluation? I've noticed from the online PDFs that there can be billions of
pages of data created. Are the BDL (.inp) file(s) and the
one-page-per-model summary of energy use generated by eQuest sufficient?

I normally have 2 models - one for proposed, another for baseline. The
averaging for baseline will have to be done outside in excel (although I
have not used the new version of eQuest - so don't know what added
functionalities it has). The rotation results are obtained by running
parametric options on the azimuth.

Also, I have seen on the EnergyGauge website that it does these extra
steps of generating a LEED report

If you look at the LEED template (I haven't seen the 2009 one yet, but
I've done a few in 2.2) you have to input your values for each of the 4
rotations. What I typically do is build two model - the proposed and the
baseline. I then set the rotations in the baseline as parametric runs,
and submit the appropriate reports from the sim files for each
simulation run.
