[EnergyPlus_Support] Very High airflow / ton of cooling

["JV Dirkes II" <jvd2pe@xxxxxxx>]

Dear EPlus Support,

I am modeling a building for a LEED project and must prepare a model
using a packaged rooftop AC system for the "baseline".  This building
is a professional (medical) office building which must also comply
with minimum airflow requirements set by the local health code.  As a
result, my System has over 1000CFM / ton and I get an error when
running the model.

The error is:
   ** Severe  ** Sizing: COIL:DX:COOLINGBYPASSFACTOREMPIRICAL
"CLGCOIL_AH1": Rated air volume flow rate per watt of rated total
cooling capacity is out of range. See Input-Output Reference Manual
for valid range.

My system is a FURNACE:HeatCool object using a
COIL:DX:CoolingBypassFactorEmpirical cooling coil.  I have selected
"design day with limit" in the ZONE SIZING (to force the known minimum
airflow rate) and "design day" in the SYSTEM SIZING.

The COIL:DX:COOLINGBYPASSFACTOREMPIRICAL object started out with
"autosize" selected for both Cooling Capacity and Airflow.  I later
tried manually inputting the Cooling Capacity without success.

I will very much appreciate suggestions about how to model this
admittedly unrealistic system!
