that. I have sat through many charette’s on ‘tree hugging’
projects to hear how the buildings orientation can affect the cooling and
heating load, let alone natural daylighting. Only to hear the wise men of 90.1
(who have never designed a building) to come up with some ‘weighted’
average to change the results. The designer ends up doing four different runs
only to find out that the architect didn’t have clue what he was trying
to do in the first place.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=blue face="Courier New"><span
style='font-size:10.0pt;font-family:"Courier New";color:blue'>1) In the
case of many new buildings (90% or more I would estimate), there is
very little latitude for changing the orientation. For example the main
street and therefore the lobby and entryway may be on one side and one
side only of the building, the aspect ratio of the building may not fit on
the lot in two of the four orientations, etc.</span></font><o:p></o:p></p>

style='font-size:10.0pt;font-family:"Courier New";color:blue'>2) The
fictitious, etheral 'averaged' building does not exist even in the computer
code of the best analysis programs we have at our disposal to date. </span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=blue face="Courier New"><span
style='font-size:10.0pt;font-family:"Courier New";color:blue'>3) All baseline
numbers for each of the four orientations would need to be extracted from the
analysis software, and averaged on a spreadsheet. Similarly each and
every EEM would need to be extracted, and the project's comparative analysis
done on a spreadsheet instead of the within the analysis software itself.

style='font-size:10.0pt;font-family:"Courier New";color:blue'>4) If this
requirement still sounds like a good idea from the comfort of your
tenured office, I say come on out and run couple of dozen real-life energy
code and LEED compliance simulations for me within budget and on deadline
in Q1-Q2 2008 and you'll begin to understand what I'm talking
about.</span></font><o:p></o:p></p>

style='font-size:10.0pt;font-family:"Courier New";color:blue'>Why not
simply allow selecting the orientation closest to, without performing
worse than, the 'average' as the baseline? This simple change would
allow the baseline numbers to reside within the analysis software.</span></font><o:p></o:p></p>

style='font-size:10.0pt;font-family:"Courier New";color:blue'>Alternatively the
eQuest developers are rumored to be working on a 90.1 Appendix G compliance
module. Upon release, if it automates the averaging I may be inclined
retire some portion of this diatribe. <o:p></o:p></span></font></p>

drop this as a requirement, and make it optional where it makes sense to do so.
Utilize by default the far more intuitive (and useful in terms of energy
incentives) 'code minimum' baseline building, oriented identically to the
proposed. This is the approach I've been able to convince our state
energy code and utility rebate reviewers to accept -- its just hardened LEED
extremists who still seem to have their head in the sand on this. <o:p></o:p></span></font></p>

<font size=2 color=navy face=Arial><span style='font-size:10.0pt;font-family:
Arial;color:navy'>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.</span></font> <br>

<font size=2 color=navy face=Arial><span style='font-size:10.0pt;font-family:
Arial;color:navy'>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.</span></font> <br>

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.</span></font>
