<DIV><SPAN class=802421316-04022009><FONT face=Arial size=2>I am trying to model
a building that will have chilled water and hot water supplied by a Central
Utility Plant. According to the attached "<FONT face=Verdana size=4><FONT
face=Arial size=2>Required Treatment of District Thermal Energy<SPAN
class=802421316-04022009> </SPAN>in LEED-NC version 2.2 (May 28,2008)", there
will be 4 models required. The first set of 2 with purchased CHW and
HW. The second set of 2 with the entire CUP modeled in the Proposed case
and a boiler/chiller plant autosized for the Baseline case.
</FONT></FONT></FONT></SPAN></DIV>
<DIV><SPAN class=802421316-04022009><FONT face=Arial
size=2></FONT></SPAN> </DIV>
<DIV><SPAN class=802421316-04022009><FONT face=Arial size=2>If that reasoning is
correct, then how do I account for the energy used by the other buildings using
the CUP? Do I add it on as Process Energy on my Chilled Water and Hot
Water loops? How do I calculate the load on the Condenser Water loop? What
if I don't know what the loads in the other buildings are?</FONT></SPAN></DIV>
