I'm modeling a Leed Baseline model.

The original building has a wide unconditioned roof. Should I consider it as a shading surface? Should I delete the unconditioned roof in the baseline model?

Get a copy of the ASHRAE 90.1 vintage you are using in your LEED certification. Consider also getting the User's Manual that goes in pair with it.

ASHRAE 90.1-2010 (but same in 2007 and 2013 as far as I remember), Table G3.1, Section 5. Building Envelope, Baseline Building column:

f. Existing Buildings.

For existing building envelopes, the baseline building design shall reflect existing conditions prior to any revisions that are part of the scope of work being evaluated.

I would model it as per the baseline building, so included an unconditioned zone that will serve as your roof cavity, or whatever is actually the case.

I was looking for an explanation of this "existing conditions prior to any revisions that are part of the scope of work being evaluated.".

It's very clear, thank you very much.
