<DIV>I do not believe the DOE-2.1E samples were translated into DOE-2.2 But most of the output reports did make it.</DIV>

<DIV dir=ltr><FONT face=Arial size=2>This is a tough one. To answer this I'm assuming that EQUEST uses the same reports at DOE-2.1e. If so, then</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>this applies, if not someone can correct me.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>The answer lies in the DOE-2 system diagram, where you'll see that any sort of "plenum" that is used as a return</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>air path is actually a heat gain to the SYSTEM return air. Hence, it does not show on the LOADS report, only as</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>additional heat gain/loss in SYSTEMS when the system is operating. This is why the roof does not appear in the</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>LOADS report. For example, take a look at the SAMP1.INP file, run 3A. (...by the way...all the DOE-2 commands</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>are exercised one way or another in the SAMP files that come with DOE-2...with a few exceptions...).</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>If you are looking for the roof loads you'll have to connect the roof directly to the spaces (there are 5 in SAMP1.INP), and</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>declare the return path as direct or ducted. By switching back and forth, you can see the impact of the plenum.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>This is not to say that plenums are trivial, as they are not. A plenum with thermal mass can be used for many interesting</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>things that can serve reasonably well as proxies for some rather complex models, for example passive solar. There's lots more</FONT></DIV>

LS-B shows the roof heat conduction into the plenum but for the conditioned space below LS-B shows no roof or ceiling conduction.
