EIR that can be to model the induced draft fans on the natural gas
boiler. When I set this EIR equal to 0 in both the "Design" and "Budget"
case models, the electric KWH under "Misc Equip" in the BEPS/BEPU is the
same. I expected that the boiler induced draft fan energy would be listed
under the "Heating" end use (or under "Fans" as a second choice)<SPAN

was a process load assigned to both models on the Secondary HW loop (I forgot to
look there - only checking the primary HW loop), and although both the load
and schedule were the same for the process load between models (thus
not showing up in my .inp file comparison), the different energy end use
probably resulted from hitting different parts of the boiler part-load
curve. </SPAN></FONT></FONT></SPAN></SPAN></DIV>

strange output reporting in my doe2 SIM file under energy end uses in BEPS and

<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>I'm using eQuest
v3.55, and am doing an ASHRAE 90.1-1999 ECB method energy study, so I have a
"Design" case model of the building according to construction documents, and
have backed out a "Budget" case model following the ECB guidelines in 90.1 (and
associated HVAC system map changes).</SPAN></FONT></DIV>

<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>CASE
1</SPAN></FONT></DIV>
<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>All
Equipment plug loads assigned to spaces are assigned as electric loads, and
are identical between by "Design" case model and my "Budget" case model.
No other internal energy sources are defined in either model. All
schedules are identical between models. No process loads are assigned to
any of my circulation loops or plant equipment.</SPAN></FONT></DIV>
<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>The differences
between input files are limited to: lighting power densities, construction
types (walls, roof, glass, etc), and HVAC system types are different due
to following the ECB modeling methodology.</SPAN></FONT></DIV>
<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>In my SIM
file under "Misc Equip" in the BEPS/BEPU reports, I have very different
electrical KWH used under "Misc Equip", and Natural gas uses have appeared in
this same "Misc Equip" category, again with very different total Therms
used.... </SPAN></FONT></DIV>
<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>Does anyone know
why the electric use under "Misc Equip" could be different between the two
models, and how natural gas use might have appeared in the "Misc Equip" end use
category</SPAN></FONT></DIV>

<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>CASE
2</SPAN></FONT></DIV>
<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>I tried reworking
the input file a bit to make the "Design" and "Budget" cases match in all of the
HVAC equipment (i.e. including all HVAC systems and thermal zones, and HVAC circ
loops and plant equipment are now identical). So, f</SPAN></FONT><FONT
face=Verdana size=2><SPAN class=401192618-07072006>or this run, the only
differences between the two input files are in Lighting loads, and Construction
types. </SPAN></FONT></DIV>
<DIV><FONT face=Verdana size=2><SPAN class=401192618-07072006>In this run, the
BEPS/BEPU reports for the two models "Misc Equip" end use category are
still different between the two models for both electric KWH used, and natural
gas Therms, but the difference between the models is much smaller than in "Case
1" above where the HVAC system types were different.....
