<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m working on an energy model for LEED
submission. It’s a high rise office building with CHW and electric
heat. The baseline building is also a centrifugal chilled water system
with electric heat and from Table 6.8.1J it should have a COP of 6.1 & IPLV
of 6.4. COP is a straight forward input into the chiller as an EIR, but up
until now I had assumed that eQUEST default curves handled the IPLV portion of
the efficiency. When I took a look at the hourly report for the chillers
though, the NPLV (calculated by the ARI 550/590-2003 equation) was 12.1, almost
double the value from the table.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In trying to match the NPLV requirement of 6.4 I tried to
create an EIR-FPLR performance curve. I did this by inputting
values of A, B, C, and D in the ARI equation that would net a value of 6.4 and
then using these four values as inputs for a custom baseline performance
curve. However when I look at the hourly report the Corrected EIR is not
what I calculated. From what I understand, Corrected EIR = EIR (input at
the chiller) * EIRFT * EIRFPLR, yet when I multiply the EIR * EIR-FT * EIR-FPLR
I get a value almost twice as large. My EIR is input at rated conditions,
so there shouldn’t be any conversion going on within the program.<o:p></o:p></span></font></p>
