<p class="MsoNormal"><span style="color:#1F497D">Essentially with the hot/cold aisle what you have is the equivalent of heat being transferred into your return air stream or plenum. Currently I don’t think there is a way to parse this out with equipment loads
in eQUEST. You can do this with lighting loads though. How about if you modeled a second lighting load with a separate meter and schedule and assigned a portion of the heat gain to the return air stream?

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hello All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m wondering what kind of success people have had with modeling data centers in eQUEST, specifically for evaluating retrofit measures like hot aisle containment, DAT reset, increased cold/hot aisle temperatures, etc. How did you set up
the zoning for the data center? What system types were used to model CRACs or in-row coolers? What kind of adjustments were made to accommodate having both overhead diffusers and CRACs?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m considering an approach of creating a separate zone for each hot/cold aisle and then adjusting the U-value for the walls between them to simulate improved containment. Sound like a plausible strategy or is it overcomplicating the issue?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any feedback is much appreciated.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you,<o:p></o:p></p>
