For a few of our firms LEED models, we tabulated the lighting values for the baseline and the changes made for the proposed model when they were asking for more information. In my experience, provide as much supporting documentation in the form of tables and lists as possible to eliminate any confusion with their template. <br>

I hope your first EAc1 review doesn’t discourage you and I understand reaching
out for guidance. <br>
<br>
1. It sounds like you did indeed model frames so
I would just provide the additional information on the conductance of the
frames and build a Window5 model to determine the assembly U-value and include
both for the reviewer. <br>
</span><span style="font-size: 11pt;"><br>
<span style="color: rgb(31, 73, 125);">2. While not the
strangest comment I’ve seen the GBCI, it is up there for random and your
response seems okay. However, is the percentage of lighting end-use energy
extremely high for the project or is there another reason they state for making
this comment? Just be thorough in your response.<br>
</span><br>
<span style="color: rgb(31, 73, 125);">3. Pumps and
auxiliary energy includes at least three things: pumps, furnace pilot
lights, and internal energy sources defined as a space load that use
electricity or natural gas. Without seeing your inp files, hard to say
though.<br>
</span><br>
<span style="color: rgb(31, 73, 125);"><br>
Good luck. It is hard to provide much more help without knowing more about the
project but hopefully this will get you started.<br>

<b>Subject:</b> [Equest-users] LEED review comments<br>
</span><br>
<span style="font-size: 11pt;"><br>
</span><span style="font-size: 10pt;">Hello
eQuest Users!<br>
</span><span style="font-size: 11pt;"><br>
</span> <span style="font-size: 10pt;">I
realize that this is an eQuest users forum and not necessarily a LEED help
forum but from reading past posts it sound like many of you have quite a few LEED
projects under your belts and I could really use some advice/help. I just
received my first EAc1 LEED review back and there are 16 comments. Is that
normal? I want to make sure that I understand how eQuest is working for a few
of these comments so that I can answer them completely and correctly.<br>
</span><span style="font-size: 11pt;"><br>
</span><br>
<span style="font-size: 11pt;"><br>
</span><span style="font-size: 10pt;">so here
are my review comment/questions:</span></p>
<ol start="1" type="1">
<li class="MsoNormal"><span style="font-size: 10pt;">"The
Proposed windows were modeled with a U-value of 0.29, which does not
appear to account for the impact of the window frames on the whole
assembly as required by ASHRAE modeling protocol." </span></li>
<ul type="circle">
<li class="MsoNormal"><span style="font-size: 10pt;">The U-Value of 0.29 is indeed the center of glass
U-Value however I included frame conductance and frame width in the
model. </span></li>
<li class="MsoNormal"><span style="font-size: 10pt;">Is that enough to account for the "whole
assembly" U-Value? </span></li>
<li class="MsoNormal"><span style="font-size: 10pt;">or do I need to find a published whole assembly
U-Value for the specified window? </span></li>
<li class="MsoNormal"><span style="font-size: 10pt;">If I do need the whole assembly U-Value, then
should I remove the frame information from the model?</span><span style="font-size: 11pt;"> </span></li>
</ul>
<li class="MsoNormal"><span style="font-size: 11pt;">"</span><span style="font-size: 10pt;">Please confirm
that the energy consumption attributed to “Area Lights” on Table 1.8.1 and
1.8.2 represents internal lighting energy consumption and demand or
provide a narrative describing any alternative uses."</span><span style="font-size: 11pt;"> </span></li>
<ul type="circle">
<li class="MsoNormal"><span style="font-size: 10pt;">the area lights information came from the
"Ambient Lights" column of the Annual Enduse Summary... so I
would say yes, it represents the lighting energy consumption and demand.
Right? </span></li>
</ul>
<li class="MsoNormal"><span style="font-size: 11pt;">"</span><span style="font-size: 10pt;">Please provide a
narrative to describe the end use for the modeled “Pumps & Auxiliary”
as shown on Table 1.8.1 and 1.8.2"</span><span style="font-size: 11pt;"> </span></li>
<ul type="circle">
<li class="MsoNormal"><span style="font-size: 10pt;">I have not been able to figure out exactly what is
contributing to this load (besides the pumps of course). What, according
to eQuest, is considered "Auxiliary"?</span><span style="font-size: 11pt;"> </span></li>
</ul>
</ol>
<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt;">I think that is it for now... I'm sure as I
start making adjustments that I will have additional questions. (The building
runs off of a central chiller plant so I've used the "Required Treatment
of District Thermal Energy in LEED-NC version 2.2" document as a guideline
and haven't quite wrapped my head around the comments related to that)<br>
</span><span style="font-size: 11pt;"><br>
</span><br>
<span style="font-size: 11pt;"><br>
</span><span style="font-size: 10pt;">I know
that one of the first things you might ask is to see my .inp and .pd2 files...
unfortunately it is for a confidential client and I am unable to share that
information.<br>
</span><span style="font-size: 11pt;"><br>
</span><br>
<span style="font-size: 11pt;"><br>
</span><span style="font-size: 10pt;">One more
quick thing... Although I do not regularly contribute to the forum I try to
read all of the threads as they come through (admittedly, I'm a little behind
right now). It is comforting to know that I am not the only one having issues
with energy modeling and eQuest. It is also comforting knowing that I can ask
you questions and I don't have to bang my head against a wall trying to figure
it all out on my own! so, thanks in advance for the help!!!!<br>
