Hi all,

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).

The problem that I have now is in the baseline.

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).

Now for step two , what the system will be ; it should be a PTHP or a ?FCU
with a chillers ?

Please I need your advice .

Best regards,
