Amanda,
 
P. G-14 in the ASHRAE 90.1-2004 User's Manual states that "self-shading" (in
the case of an L-shaped building for instance) is ignored in the baseline
building but credited to the proposed building when it is a benefit.
 
Regards,

Subject: [Bldg-sim] ASHRAE 90.1 & Shading from adjacent buildings


Can anyone confirm or refute that shading provided by adjacent buildings is
allowed to be included when modeling according to ASHRAE 90.1 PRM or ECB
protocol?  I am not able to find any statements in the document related to
this specific issue.  
 
If it is allowed, does it need to be provided on both proposed design and
baseline models?  Or can it only be modeled on the proposed design like all
other shading devices?
