components. You can switch it on/off by using the direct return option, but then this chops out those surfaces from participating in the simulation, depending on how you’ve linked up the plenums to the spaces in the next-to commands (or how the DOE2.2 robot
does it).<o:p></o:p></span></p>

</div>
<div>
<p class="MsoNormal">- The hospital does have plenums and the heat gains/losses thru the plenum exterior surfaces would affect the return air to whatever system is serving that space. Will the system not see this load? I suspect it does and thus other than
not being able to see the peak load, is there any other downside to having plenums?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">- If I want the plenum loads to show up in the peak loads report by not creating plenums, I suspect I will see unmet loads in these plenum-less and thus larger zones as the designed equipment capacities will not be able to meet loads. <o:p></o:p></p>

not always obvious. For example, in DOE-2 if you declare the return air path as having a plenum and then assign the walls, roof, floor, etc. to that plenum as the zone, then the heat gain/loss from that surface is assigned to the air that is returning from
the zone on its way back to the HVAC system and therefore, it will not show up in the peak load in LOADS because it is a heat gain to the return air and not the zone. You can prove this to yourself using the SAMP1 file that comes with DOE-2.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="color:#1F497D"> </span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="color:#1F497D">For example, in the SAMP1.INP file that comes with DOE-2, RUN 3A, there is a single story 5 zone model with a plenum. What you will notice when you run
this model is there is no roof load in LOADS because the single story building has a plenum and the roof load has been assigned to the plenum as the zone. The load from the roof does show up when you assign a SYSTEM where it then appears as heat gain/loss
from the return air. </span><o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="color:#1F497D">To “see” the load from the roof you have to remove the plenum and re-proportion the roof to the zone area. Then the roof shows up in the component loads
