color=blue size=2>This is true, however, even with an existing building, you as
the designer/engineer have the option of "working" the facades and applying
appropriate fenestration, shading, etc... you can still make good/bad decisions
and the fact that your footprint is fixed should not give the design team a
waiver from the fact that the sun still rises in the east and sets in the west.
In fact it may be a benefit if perhaps your building is shaded on the west
by itself.</FONT> <BR><FONT size=3> </FONT> <BR><FONT face=Arial

<BR><FONT face=Arial color=blue size=2>Dear LEED Info,</FONT> <BR><FONT
face=Arial color=blue size=2> </FONT> <BR><FONT face=Arial color=blue
size=2>There has been a lot of chat on this item and I wonder if there is a
USGBC position – I found no reference to this in the CIR’s:</FONT> <BR><FONT
face=Arial color=blue size=2> </FONT> <BR><FONT face=Arial color=blue
size=2>Do existing buildings undergoing renovation require the four-point
compass orientation analysis?</FONT> <BR><FONT face=Arial color=blue

<BR><FONT face=Arial color=blue size=2> </FONT> <BR><FONT face=Calibri
size=2>Jeffrey,</FONT> <BR><FONT face=Calibri size=2> </FONT> <BR><FONT
face=Calibri size=2>If the existing building being renovated is pursuing LEED-NC
rather than LEED-EB, then it would indeed be required to undergo the specified
analysis. This analysis is used to establish the baseline for energy
performance using the ASHRAE standard. LEED doesn’t have any specific
exemptions for existing buildings in this requirement, but if ASHRAE has some
kind of exemption, we will honor that.</FONT> <BR><FONT face=Calibri
size=2> </FONT> <BR><FONT face=Calibri size=2> </FONT> <BR><FONT
face=Arial color=blue size=2>So I guess the question then becomes an
interpretation of the Appendix G (Table G3.1 (f)) comment for existing
buildings. Rotate or not?</FONT> <BR><FONT face=Arial color=blue
size=2> </FONT> <BR><FONT face=Arial color=blue size=2>My take has always
been that new buildings have the option to consider orientation but existing
buildings cannot be re-oriented so rotating the model does not really prove
anything. </FONT><BR><FONT face=Arial color=blue size=2> </FONT> <BR><FONT
face=Arial color=blue size=2>Any 90.1 code committee members or others out there

[BLDG-SIM] LEED Building Orientation</FONT> <BR><FONT face="Times New Roman"
size=3> </FONT> <BR><FONT face=Arial color=#000080 size=2>I am not the
authority, Keith, but I believe that your interpretation (that existing
buildings do not get rotated in the baseline) is consistent with the intent of
Appendix G. In new construction, the decisions regarding building
orientation will affect performance and that performance should be measured
against the baseline (although, there are cases, such as a building that adjoins
buildings to either side, where rotating the baseline through all four
orientations does not make sense). If you’re improving an existing
building, the existing conditions of building enclosure components, including
orientation, are an appropriate baseline. When we apply Appendix G to
existing buildings, we have also found that “existing building envelopes”
sometimes needs to be parsed into existing building envelope components.
For example, in a mill rehab, the bearing walls may be serviceable and
appropriately modeled “as is” in the baseline, but missing windows or windows
that are clearly not serviceable we model as per the ASHRAE minimum
compliance.</FONT> <BR><FONT face=Arial color=#000080 size=2> </FONT>
<BR><FONT face=Arial color=#000080 size=2>You should note, also, that an
addendum to the standard has removed the provision in the table under G3.1, 5c
to distribute windows uniformly in horizontal bands across the four
orientations. That should make all of our lives easier.</FONT> <BR><FONT

<BR><FONT face="Times New Roman" size=3> </FONT> <BR><FONT face=Arial
size=2>I am modeling an existing building for Energy & Atmosphere Credit 1:
Optimize Energy Performance. In LEED and table G3.1 No. 5(a) of ASHREA Standard
90.1-2004, it states that “the baseline building performance shall be generated
by simulating the building with its actual orientation and again after rotating
the entire building 90, 180, 270 degrees, then averaging the results”. However
table G3.1 No. 5(f) of ASHREA Standard 90.1-2004 states: “for existing building
envelopes, the baseline building design shall reflect existing conditions prior
to any revisions that are part of the scope of work being evaluated.” Would this
mean that you do not need to simulate the building for the four orientations? It
just doesn’t seem to make sense to simulate the building in such a manner if it
is existing. I am new energy modeling for LEED credit and sincerely appreciate
any assistance.</FONT> <BR><FONT face=Arial size=2> </FONT> <BR><FONT
