<DIV dir=ltr><FONT size=2 face=Arial>It sound like the cooling for the building
is being designed and installed, but will rely on a future central chilled water
plant. If this is correct, you should follow the DES Guidelines available on the
USGBC website. The most recent version (issued last August) can be found with
this link. <A

<DIV dir=ltr><FONT size=2 face=Arial>Depending on the LEED registration date,
using this version may be optional, but the first version required two sets of
models for projects pursuing more than 2 points for EAc1. Hope this
helps!</FONT></DIV>

<DIV>Ladies & Gentlemen:<BR><BR>I am modeling a government dormitory that
has four pipe Vertical Fan Coil units with a hot and chilled water
coil.<BR><BR>The chilled water coils will not be used for a year or two when it
is anticipated that the district cooling plant will be operational.
<BR><BR>ASHRAE 90.1 requires that we model cooling even if there is no cooling
being installed. I modeled the baseline with DX PTAC units containing a
hot water coil.<BR><BR>I would like to model the proposed as having chilled
water cooling even though it has not been installed yet. I would use the
minimum efficiency for the chiller as defined by 90.1.<BR><BR>Has anyone tried
submitting a similar project to LEED?<BR><BR>Thank you,<BR><BR>Paul
