I agree with Kent for the most part, and that's why I accepted his answer.
But as far as including the adiabatic areas in the Window to Wall Ratio (WWR), I would tend to disagree, though I don't have hard facts to support this.
One thing to note is that when you see a wall to adiabatic, softwares such as eQuest will remove it from the wall area and windows+wall area.
Though I agree you could take the "gross above-grade wall area" the way you want it, this wall is made adiabatic for a reason: it's abutting an existing building. My guess is that the intent was to mean the "gross above-grade wall area that is available to install windows (= that has a view)".
There might be a Credit Interpretation for LEED somewhere on the matter, or a request to ASHRAE for clarifications?
