<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m a new eQUEST user and am a little confused about
how to set up my model. I’ve searched through the archives as a starting
point but could use some advice specific to this project. First let
me describe what I’m trying to model and then I’ll describe what I’ve
done and my questions.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The building has an absorption chiller, a standard VAV
system and radiators around the perimeter. Finally, the building
purchases steam to provide heating (both VAV heating and baseboard heating) as
well as to power the absorption chiller. The purpose of modeling the
building is to compare a “good, better, best” set of windows and
their impact on energy consumption (I don’t think this will be difficult
as I’ve set parametric runs like this up before).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I started in DD wizard and set up my footprint, envelope,
loads and the standard shell parameters. The zoning I’ve used is a
simple perimeter+core. I have an ok grasp of the building modeling, it’s
the HVAC system modeling that I have trouble with. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I finished my building parameters, I added a second
air-side system which is HW baseboards (the first is the standard VAV w/ HW
reheat). <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This has led to my first question: Can a zone have both VAV
conditioning and baseboard heating? It seems as though when I set a zone to
have both systems, the baseboards become turned off. Which leads to my
second question: If I can’t have VAV cooling in the perimeter, do I need
to set my vertical walls to “air (none)”?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So far, so good: everything is still working. The last
step I do is to enter the detail data edit, under Water Side HVAC I create a
Steam Meter and place it on my hot water loop. Then I delete my boilers and
appear to be set, I can simulate and everything.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This leads to my third question: I’m not sure what the
best way to check that my system is performing as expected. Additionally,
I’ve looked through the archives and read the emails you all send around
(VERY helpful BTW, thanks!) and this just seems to easy. I’ve attached my
inp file, hopefully that help. Thanks for reading through this massive email.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
