<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>This is a much more
clear explanation, thanks! I’m copying this to the mailing list to
seek others’ input. There may be a more time-effective way to
do this and I have never personally modeled this specific class of
equipment. <o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='color:#1F497D'>I’m not certain
if this is feasible or not, but I might explore the possibility of treating
this like an ordinary electric 4-pipe system, but to tie the electric energy
use of this equipment to a separate electric utility meter within the
program. Then, set that meter’s rates to match your equivalent gas
rates for the same energy. Conceptually this seems simpler than equating
a coordinated boiler/chiller to your equipment, but I don’t know whether
this might cause different troubles when it comes to nailing down the
performance curves…<o:p></o:p></span></p>
