<DIV dir=ltr align=left><SPAN class=004200419-23012007><FONT face=Arial
color=#0000ff size=2>I am running into a few office/data center buildings where
the main office areas are cooled by conventional chillers and the data
center/server areas are conditioned by either Liebert type package units or 40%
glycol-to-water mix chillers (colder climates that still need servers cooled).
Naturally, both units will be on the same electric meter.</FONT></SPAN></DIV>

color=#0000ff size=2>The standard DOE-2 does not model glycol cooling, and
a commercial building does not need the refrigeration version of eQuest.
Usually, I know the kw/ton (or the moral equivalent) of the glycol cooling
source. But glycol/water does not have the same heat absorption properties as
straight shot water to follow the load.</FONT></SPAN></DIV>
