<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I have a building that gets chilled water and heating water from
a district plant – and they are trying to LEED certify the building. So I’ve
been using the document “Required Treatment of District Thermal Energy”, but we
have been given the efficiency of the plant as a whole. The university meters
the amount of energy they put into the plant and what they get out and gave us
an efficiency for the heating plant at around 76% and 88% for the cooling
plant. I’ve modeled the building with purchased water for Step 1 of the
document, now I’m trying to model the building and plant for the proposed
design in Step 2 (Aggregrate Building / DES Scenario).<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I had hoped to be able to create a chilled water meter and
heating (steam) meter and enter the equipment efficiency in where it asks for
Source-to-Site Eff (shown in the screenshot). Unfortunately, no matter what
number I put in there, the resulting “Annual Energy Consumption by Enduse”
stays the same. Interesting also that the default for the Equipment Efficiency
for the chilled water meter is 1.5 and the default for the steam meter is 0.6.
The help information on each is different too, one calls for the ratio of the
site to source and the other calls for the ratio of source to site – WHICH IS
IT?<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Also, since the result doesn’t show up in the “Annual Energy
Consumption by Enduse” report, where can I get the results that show the inefficiencies
in the plant? The only report I’ve found that is even remotely useful would be
the PS-A Plant Energy Utilization report, but that doesn’t make sense. It
shows the source energy as being 2.5 times the site energy. It seems like that
has to be taking something else into account that I’m not realizing or
something.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>How can I enter the proposed design (existing plant) information
if I have the overall efficiency of the plant and that’s all? (the real plant
has multiple chillers of differing types and it would be impossible to model it
how it runs, and same with the heating plant.)?<o:p></o:p></span></p>

that it’s working right? Is there a report that I don’t know about that will
show what I’m looking for better?<o:p></o:p></span></p>
