[EnergyPlus_Support] For help:room air models

["maize_lee" <liyuming1123@xxxxxxx>]

Thank you!

I have another problem of this model.
The result shows that the cooling load of roof-glazed atrium is 
zero. I have set the infiltration of the atrium 0.4ACH,so it 
shouldn't have no cooling load. 
last time,I calculated the model with version2.2.the result is zero. 
today, I translate the model to version 3.0, but the result is still 
zero.

 I have upload the IDF file to the group, please help me see what is 
the problem of the model. Thank you very much!

By the way, the input of dimentional room air model is the 
temperature gradient of conditioned period or unconditioned period?

your last posting.

pattern of the roomair model, but some warning are appeared and the 
results seemed there was no cooling load in the atrium.there are 
many warnings like this:Warning ** Problem in non-dimensional height 
calculation, too high surface:REVERSE_EL11_CORRIDOR1-ATRIUM WALL in 
zone: 1F_ATRIUM** ~~~ ** **** Average Ceiling height of zone is: 
42.000** ~~~ ** **** Surface Maximum height is: 44.000** Warning **

** **** Average Ceiling height of zone is: 42.000** ~~~ ** **** 
Surface Maximum height is: 44.000** Warning ** Problem in non-

WALL (G.C6.I20) in zone: 1F_ATRIUM** ~~~ ** **** Average Ceiling 
height of zone is: 42.000** ~~~ ** **** Surface Maximum height is: 
44.000So can anyone tell me what the warnings mean? And when using 
nondimentional roomair models, how does the model calculate the 
cooling load of the Atrium?Thank you!
