[Bldg-sim] ASHRAE 90.1-App G: Site Shading

[gail]

Appendix G does specifically state that for existing buildings being gutted,
the Baseline building envelope should be modeled based on the existing
conditions prior to any revisions that are part of the scope of work being
evaluated (Table G3.1(5)(f)).  Therefore, if you are modeling self-shading
and adjacent buildings in the proposed case for an existing building, they
should also be modeled in the base case for existing buildings.
