Re: [EnergyPlus_Support] Regarding an error





You've listed a multitude of warning messages.  Which one(s) are you having problems with?

Hi,
 
I'm working with the hospital prototype of DOE-2 in Phoenix climate. I'm having problem to identify the following error message. If someone can give me any feedback on that it would be a great help.
 
Thanks,
Sadia Haque
