<DIV><FONT face=Arial color=#0000ff size=2>I initially interpreted it the same
way the Cam says below however the LEED reviewer disagreed with me and said I
should model it as Sam describes below.</FONT></DIV>
<DIV><FONT face=Arial color=#0000ff size=2></FONT> </DIV>
<DIV><FONT face=Arial color=#0000ff size=2>I think the catch is this: on page 6
it says " For such projects the secondary equipment within the building is
modeled as described in table 3 above (i.e., the same way as in step 1" it also
says "The proposed case modeling requirements differ from those in ASHRAE
90.1-2004 Appendix G; however, the baseline case is modeled as instructed in
Appendix G."... I think what this means is that the baseline models should be
the same in both case 1 and case 2... and everything should be modeled as
described in appendix G except the specific type of system as listed in table
3.</FONT></DIV>

the same system from step 1 to step 2 - fan coils with hot water boiler - per
Table 3 in the DES guidelines. In step 2, you will create a minimally compliant
cooling plant based on Appendix G modeling parameters and attach the fan coils
to the plant.<BR><BR>Sam<BR>--<BR>Sam Mason<BR>Atelier

Re: [Equest-users] Baseline Modeling as per LEED district
coolingrequirements<BR><BR>Hi all,<BR><BR>I Am working now on a Residential
tower supplied by a district cooling plant . The proposed design completed as
per the LEED required treatment of district cooling . and two model performed
(one with virtual chillers and the other one with chilled water meter to reflect
the chilled water cost).<BR><BR>The problem that I have now is in the
baseline.<BR><BR>In step one (modeled as cost neutral), the document say that
the system will be based on table 3 instead of ASHRAE appendix G , system 2 (FCU
will be use instead of PTHP).<BR><BR>Now for step two , what the system will be
; it should be a PTHP or a FCU with a chillers ?<BR><BR>Please I need your
advice .<BR><BR>Best regards,<BR><BR>Mohammad Al-Masri<BR>Simulation
