<p class=MsoNormal><font size=2 face=Verdana><span style='font-size:11.0pt;
font-family:Verdana'>I’m hoping someone can help me figure out how to get
eQuest to perform a unit sizing according to a user-defined cooling design day
as opposed to the hourly weather data.<br>
<br>
Situation: I’m modeling a four-story residential building in <st1:place
w:st="on"><st1:City w:st="on">West Palm Beach</st1:City>, <st1:State w:st="on">FL</st1:State></st1:place>
where each apartment uses a split system. I’m getting an odd
situation where eQuest tells me the peak cooling load is being set in January,
and while I haven’t 100% figured that one out, I suspect if I tell the
program to size the unit based on a cooling design day derived from ASHRAE data
then that issue will go away.<br>
<br>
Problem: I can’t figure out how to define the outside air conditions for
the cooling design day.<br>
<br>
I know there was a recent discussion on using eQuest to do equipment sizing,
but I can’ find that discussion on the archives. Here’s what
I have figured out:</span></font><o:p></o:p></p>
<ul type=disc>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'><font size=2 face=Verdana><span style='font-size:
11.0pt;font-family:Verdana'>If you’re modeling a location outside <st1:State
w:st="on"><st1:place w:st="on">California</st1:place></st1:State>, you
have to manually input temperatures and humidity for the design day.
These are going to be worse than probably anything in the weather
data file because they’re extremes (the ASHRAE 97.5% or similar). </span></font><o:p></o:p></li>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'><font size=2 face=Verdana><span style='font-size:
11.0pt;font-family:Verdana'>eQuest lets you define “CDD”
schedules where you can specify percentages for occupancy, lighting, misc
equipment, etc. I know how to do this.</span></font><o:p></o:p></li>
</ul>
<p class=MsoNormal style='margin-bottom:12.0pt'><font size=2 face=Verdana><span
style='font-size:11.0pt;font-family:Verdana'><br>
So where do I go in eQuest to define my cooling design day exterior conditions?
Is it in the Wizard? Do I do it via Detailed Data interface?
Do I have to go all the way out to the BDL file, alter it in a text
editor, and then run DOE2 separately from eQuest? (I haven’t
figured out how to make changes to a BDL and run it in eQuest without eQuest
overwriting any of my changes.)<br>
<br>
Help. Please.<br>
