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:11.0pt;font-family:"Calibri","sans-serif"'><br>
<span style='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>
</span><br>
<span style='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>
</span><br>
<span style='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> <span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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>

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

and haven't quite wrapped my head around the comments related to that)<br>

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>
