thread to see if anyone has insight. How do the roof conduction loads translate
to HVAC loads?</span></p>

<p class="MsoNormal"><span style="font-size: 11pt; font-family: "Calibri","sans-serif"; color: rgb(31, 73, 125);">Based 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></p>

baseline building energy usage is much lower than expected and in trying to
track down the cause I’ve found that the “Building Peak Load
Components” lists no roof heat gain or heat loss. I did find that
there is a gain/loss located in the upper floor plenum and it’s shown in
the “Space Peak Load Components”. </span></p>

the plenum not considered part of the building? I’m concerned that
the plenum walls and roof are not being included in the energy modeling run.</span></p>
