meter onto the DHW loop, it still charges (in my case) natural gas. There is no
option to setup the DHW heater with any fuel except electricity or natural gas.
I was hoping not to go through converting steam into electricity. Is it
possible to take the MBTU from the BEPS report and convert it into steam
somehow?<o:p></o:p></span></font></p>

font-family:Arial'>I am trying to put together a model for a building on a
University campus that uses centrally generated steam to create domestic hot

somebody might have some guidance for me.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>My initial idea was to use a steam meter connected directly
to the DHW loop, and modify the efficiency to account for the heat exchanger,
but this doesn’t seem to work as there are no options for adding a
storage tank to the loop in this setup. There may be other issues as well
that I’m not thinking of.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The trial I’m working on now is to use an electric DW
boiler in combination with a steam turbine generator. The steam turbine
generator would be connected to the district steam hot water loop, and the
electricity generated would be put to a new, dedicated electric meter for this
specific purpose, which is the assigned to the electric DW heater. The
waste heat of the turbine would not be set up to just dissipate rather than be
used. The issue I’m having with this, is that I can’t figure
out how to size the kW of the steam turbine generator, and I can’t let
eQuest autosize it. I’m basically creating an imaginary electrical
load. Would I just convert the BTU/hr of the actual unit into kW, and set
the EIR of the generator to reflect the efficiency of the HX and other losses
in the actual system? Or is this method blatantly wrong for some reason
I’m overlooking?<o:p></o:p></span></font></p>
