<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">One quick fix we have found is to make sure to specify Design Days for both cooling and heating. On the “Project & Site” tab, right click the project name at
the very top of the component tree and then select “Create Design Day” and enter the design temperature information. You’ll need to do this twice to cover cooling and heating design conditions. This reduces simulation time by a fair amount as it seems to cut
down on the repeat load calculations that run in 7175 without design day conditions specified. We have still observed longer run times in general, but this helps.<o:p></o:p></span></p>

<p class="MsoNormal">Hi All,<br>
<br>
I always read everyone's posts but have never posted. Thank you for all of the informative exchanges over the years.<br>
<br>
I have been using the 7175 DOE2.3 version of eQuest since it was released and have found the simulation times to be significantly greater than the 7173 DOE2.2 build (even with creating the heating and cooling design days in detailed mode). I'm wondering if
anyone else has experienced this, and, if so, if you have found a way to speed up simulation times. In smaller models (~50,000 sf) it is not a big deal but with larger models (~350,000 sf+) I find that it impacts productivity greatly.<br>
<br>
Any input would be appreciated.<br>
<br>
Thanks!<br>
<br>
Christina<o:p></o:p></p>
