[Equest-users] System per Area for Packaged VAV with Elec Reheat

[Lars Fetzek]

Rick,
 
     Just guessing - have you tried directly editing the .inp file in a text
editor?  Sometimes, this has helped me with other issues.  But sometimes,
upon opening and saving the project again in eQuest, eQuest will modify the
.inp file again.  Anyway, it might be worht a try.

Hi, 
 
I am trying to follow the advice below to revise the fan power input. After
calculation, the result is 0.00101 kW/cfm, as I entered in the model (as
attached screen shows). However, I found that the simulation result is not
sensitive to this input (in blue).  I know the rule is "Use either
SUPPLY-STATIC and SUPPLY-EFF or SUPPLY-DELTA-T and SUPPLY-KW/FLOW." , but
now, both "SUPPLY-STATIC and SUPPLY-EFF" AND "SUPPLY-DELTA-T and
SUPPLY-KW/FLOW" appear in the window. I attempted to remove "SUPPLY-STATIC
and SUPPLY-EFF" but failed. Could anyone kindly advise how to make this
work?
 
By the way, I am quite curious to know if problems still exist in the
revised models after reviewed by GBCI for the second time, do we have to
appeal by then? Is it likely to happen? I am afraid I cannot make sure all
inputs are correct..Sorry for being off-topic.
 
Many thanks,
Rick

Hi Rick,

 

You must entered the Fan power as kw/cfm in every system in baseline system

 

Thanks

Ashu

Hi All,
 
We have a 4-story office building to be LEED certified. The Baseline system
is packaged VAV with elec reheat. After reviewed by GBCI, the comment is:
 
"The Baseline case fan power does not appear to be modeled in accordance
with G3.1.2.9. Please revise the sum of the supply, return, exhaust and
relief fans for each HVAC system to be equal to the power calculated in
G3.1.2.9."
 
Now I am ready to revise the model, but I am not sure in the baseline case,
whether I must choose "system per shell", "system per floor" or "system per
zone". Could anyone advise? Thanks in advance. 
 
Rick, PE, LEED AP
