<DIV>Actually, the text you refer to means that the building itself, meaning its own walls and roof, should not shade itself. That sentence probably sounds confusing. Think of an L-shaped building and how one side of the L could shade another side of the L at certain times of the day/year. If you're using DOE2, you can just use this code at the beginning of where your spaces and surfaces are defined:</DIV>
<DIV> </DIV>
<DIV>SET-DEFAULT FOR EXTERIOR-WALL</DIV>
<DIV>SHADING-SURFACE = NO ..</DIV>
<DIV> </DIV>
<DIV>This is for your Baseline. For your Proposed Design, change the "NO" to a "YES."</DIV>
<DIV> </DIV>
<DIV>App. G, Table G3.1 states that, for the baseline, "no shading projections shall be modeled. Manual window shading devices such as blinds or shades shall not be modeled." This means your baseline shouldn't have any fixed shades in it. For the proposed design, only automatically controlled shades/blinds can be modeled, and any "permanent shading devices such as fins, overhangs, and light shelves may be modeled."</DIV>
<DIV> </DIV>
<DIV>As far as the trees and shades/reflectance from neighboring buildings, I haven't found this addressed in the LEED or App. G documentation. Has anyone else?</DIV>
<DIV> </DIV>
<DIV>Hope this helps!</DIV>

<P class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Appendix G states that for the baseline building performance, “the building shall be modeled so that is does not shade itself.” I interpret this to mean that only shades that are part of the building should be removed in the baseline case, and that any fixed shades not connected to the building (i.e. trees or neighboring structures) should still be modeled in the baseline case. Is this a correct assumption, or should all sources of shading, such as trees, be removed in the baseline case? <o:p></o:p></SPAN></FONT></P>
