The way it works is as follows:
-Step 1, Compare proposed model to baseline model with existing wall and use this to achieve points
(p. 181 of LEED NC 2.2 EA Credit 1 Calculations Section)
-Step 2, Compare proposed model to baseline model with ASHRAE 90.1 walls as a check to make sure proposed is at least this efficient
(At the moment I can't remember where I read this, maybe a CIR? Can anyone confirm this?)

I am working on a renovated building and am wondering whether the
baseline exterior wall should be the current existing wall or the
baseline wall system as described by ASHRAE 90.1. If it matters, we are
going for LEED NC points because of the extent of the renovation, not
LEED EB.
Does anyone have any experience with this?
