<FONT SIZE="4"><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>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 West Palm Beach, FL 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:<BR>
</SPAN></FONT></FONT><UL><LI><FONT SIZE="4"><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>If you’re modeling a location outside California, 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></FONT><LI><FONT SIZE="4"><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>eQuest lets you define “CDD” schedules where you can specify percentages for occupancy, lighting, misc equipment, etc. I know how to do this.<BR>
</SPAN></FONT></FONT></UL><FONT SIZE="4"><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'><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>
