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>

<p class="MsoNormal"><span style="COLOR: rgb(31,73,125); FONT-SIZE: 11pt">Heather,<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> <br>Sam<br></span><br></span><span style="FONT-FAMILY: Consolas; COLOR: rgb(31,73,125); FONT-SIZE: 10pt">--<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 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 style="MARGIN-BOTTOM: 12pt" class="MsoNormal"><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>
