<p class="MsoNormal"><span style="color:#1f497d">From the looks of the image it also appears that you have plenums in the building, which further complicates the simulation, and for reasons that are 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.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><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.

<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><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 in the LOADS peak load report.

<p class="MsoNormal"><span style="color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:#1f497d">I suspect that deep inside the bowels of the model you showed below this is going on.<u></u><u></u></span></p>

<p class="MsoNormal"><span lang="EN-CA">Hey everyone,<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-CA"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-CA">The hospital I am working has different footprints for each level (see snapshot below). While going thru the bldg. envelope in detailed mode, I noticed that the surfaces separating interior floors are modeled as exterior
roofs. Now it’s been a while since I’ve modeled using eQUEST but I’m sure these surfaces should be modeled as interior floors.<u></u><u></u></span></p>

<p class="MsoNormal"><span lang="EN-CA">So a couple questions:<u></u><u></u></span></p>

</span></span></span><u></u><span lang="EN-CA">What did I miss in the DD Wizard? One shell was made for each elevation, and for the each above grade floor, below is the input entered for the floor info. Is this where I made my mistake? Or do I need to
model the shells with and without roofs separately? <u></u><u></u></span></p>

</span></span></span><u></u><span lang="EN-CA">Is there a fast way to change what’s needed without deleting each “interior roof” and replacing it with an interior floor or going back into the DD wizard? Pretty sure not but here’s hoping!<u></u><u></u></span></p>
