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>

<FONT COLOR="#1F497D">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>
</FONT><BR>
<FONT COLOR="#1F497D">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>
</FONT><BR>
<FONT COLOR="#1F497D"> <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>

</SPAN></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'><BR>
</SPAN></FONT><FONT FACE="Times New Roman"><SPAN STYLE='font-size:12pt'> </SPAN></FONT><FONT SIZE="2"><FONT FACE="Arial"><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></FONT><FONT SIZE="2"><FONT FACE="Arial"><SPAN STYLE='font-size:10pt'>so here are my review comment/questions:<BR>
</SPAN></FONT></FONT><OL><LI><FONT SIZE="2"><FONT FACE="Arial"><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." <BR>
</SPAN></FONT></FONT><UL><LI><FONT SIZE="2"><FONT FACE="Arial"><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></FONT></FONT><LI><FONT SIZE="2"><FONT FACE="Arial"><SPAN STYLE='font-size:10pt'>Is that enough to account for the "whole assembly" U-Value?
</SPAN></FONT></FONT><LI><FONT SIZE="2"><FONT FACE="Arial"><SPAN STYLE='font-size:10pt'>or do I need to find a published whole assembly U-Value for the specified window?
</SPAN></FONT></FONT><LI><FONT SIZE="2"><FONT FACE="Arial"><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></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'> <BR>
</SPAN></FONT></UL><LI><SPAN STYLE='font-size:11pt'><FONT FACE="Trebuchet MS">"</FONT></SPAN><FONT SIZE="2"><FONT FACE="Arial"><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></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'> <BR>
</SPAN></FONT><UL><LI><FONT SIZE="2"><FONT FACE="Arial"><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? <BR>

</SPAN></FONT><UL><LI><FONT SIZE="2"><FONT FACE="Arial"><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></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'> <BR>
</SPAN></FONT></UL></OL><FONT SIZE="2"><FONT FACE="Arial"><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></FONT><FONT SIZE="2"><FONT FACE="Arial"><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>
