size=2>Appendix G is pretty clear that self-shading in the baseline case is
not permitted. For whatever reason I seem to remember seeing something
similar about shading from adjacent buildings. I have heard from
mechanical consultants that they never factor in adjacent building when sizing
equipment since they can't foresee what will happen to them in the future.
But for a campus setting, where the owner has a commitment not to tear the
buildings down, maybe you can argue otherwise.</FONT></SPAN></DIV>

credit should be taken for shading from adjacent buildings. The base case
procedure takes pains to normalize the baseline analysis to a building that is
neutral to solar gain and there have been requirements in the past (and still
are?) that the building cannot self-shade itself. Other Bldg-sim readers
probably can provide a more of official reading of the actual rules and I am
interested in hearing their rationales.<o:p></o:p></SPAN></FONT></P>

ECB or Appendix G allow you to take credit for shading due to surrounding
buildings. Can anyone provide a specific reference to the code or LEED
Reference Guide where that is stated? I understand the rationale for a
single building, but if I'm working on a campus with single ownership and the
buildings have a 30 year contract to be owned and operated, I feel like I should
be allowed to take a credit for reducing the solar heat gains due to adjacent
buildings. Any thoughts?</SPAN></FONT><o:p></o:p></P></DIV>
