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

[Bishop, Bill]

What if it is an existing building, in which case, "the baseline
building design shall reflect existing conditions prior to any revisions
that are part of the scope of work being evaluated."  (From Table G3.1
No. 5 (f).)  Do I ignore items (a) through (e) in their entirety,
including no self-shading (and, for that matter, the whole
average-of-four-orientations requirement)?  And there is still the
question of shading from adjacent buildings.

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.

	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?  

	 

	Best Regards,
