create a new Utility Rate. Name it, create from scratch and set the type to
Steam. Assign your three new steam meters to the rate under "Steam Meters
Served" in the General tab. Assign a Uniform Energy Charge if appropriate under
the Energy/Demand tab. You'll have to calc what the effective $/unit is based on
the condensate billing. Remember this is calculated based on steam, not
condensate, so you'll have to factor in losses.</FONT></SPAN></DIV>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Hello – I’m relatively new to eQuest
(though have used other modeling software extensively) and I’m modeling a
building on a campus with a central steam plant. The building is billed
for steam use based on gallons of condensate returned. The building has
steam-hot water heat exchangers for the MZ air handling units and the DHW
system. It also has an absorption chiller on the steam loop. There
is no natural gas use in the building. I set up steam meters in the loops
for these “end uses” but I’m running into problems. I searched the
archives and found a couple questions posted in past years about steam meters
but didn’t really find the answers I need.</SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></SPAN></FONT> </P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">1) I can’t directly model the DHW
w/steam so apparently I have to model it as natural gas? Or can I model it
as a direct load in the steam meter properties - direct load
screen?</SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></SPAN></FONT> </P>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">2) No steam use is showing up when I
run the simulation. I went into the Master Meter screen and it only allows
(apparently) electric and fuel meters. Under fuel meters, there is not a
steam option, unless one is supposed to select “other”. Does the Master
meter need to know about the steam meters? And if so, how do I tell
it? Is there something else entirely that I should be doing that I’m
missing? (Since eQuest’s help screen is a DOE2 help screen, I’m not having
much luck with understanding how it applies to eQuest in this
case.)</SPAN></FONT></P>
