Kent,

Yes, for existing buildings, use the wall & roof assemblies, glazing properties etc. of the existing building for the Baseline values. Also, you don't have to simulate in four orientations.

Regards,
Bill

This question isn't eQuest specific, but deals with 90.1 interpretation.

For an existing building, with regards to shell alterations, G3.1.5-f says that "the baseline building shall reflect existing conditions prior to any revisions that are part of the scope of work being evaluated."  Is this statement as far-reaching as I believe, indicating that U-values, SHGC etc, listed in Tables 5.5 and Appendix A are ignored in a similar way as done in the proposed, since the "baseline" in this case is a real design, rather than a hypothetical baseline?
