color:#1F497D'>I took a look at the DOE2.2 Vol.4 Manual and I think my confusion
is due to the information that is reported in the LS-x reports. The load reports
are based on the design insidoor temperatures (e.g., 70F). Therefore, the loads
reports do not show any interior surface conduction unless you have different design
temperatures in adjacent spaces.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>During the simulation, unconditioned spaces (e.g., the plenum)
will not have constant temperatures, so hourly reports should show the roof
heat being transferred to the space via interior surfaces. I haven’t actually
gone fishing for the correct hourly reports yet, but I’m guessing they’re
there.<o:p></o:p></span></p>

on the models I’ve run it’s obvious that roof conduction is being accounted
for on the HVAC side and it appears to be about the right magnitude. However,
added roof conduction loads to the plenum do not translate to any added space
loads or building loads in the LS-x reports. Does anyone have insight
on how eQuest is handling them and why they do not show up in space or
building loads reports?</span><o:p></o:p></p>
