Dear John,

This is a commercial Interior project under LEED. The project is occupying only 2 floors in a 8 floors building. Only for those two floors, internal loads and the air side HVAC varies between base and proposed case. Rest of the floors, building envelope and plant side is modeled identically between base and proposed case. I don't know how equest calculates secondary loop capacity and the flow.

Regards,
Rathnashree

Rathna:
Did you
make changes to your load in the Proposed (less lighting,
improved HVAC control, VAV/VFD). For whatever reason, eQuest
seems to change things based on a different load and load
profile.
But I will
let other chime in as well.

Dear
All,
I have
modelled the central plant identical in base and proposed
case as it is an existing one. I have provided the capacity,
flow rate, power and efficiency values for all the pumps.
This is an air cooled chiller.
When i
compared the PV-A report for both base and proposed case,
the secondary chilled water loop capacity (Mbtu/hr) and loop
flow (gpm) varies between base and proposed case. I am not
able to make it identical even though i have not autosized
anything.
Please
let me know if there is any way to make PV-A report
identical to base and proposed case.
Regards,Rathnashree
