Re: [EnergyPlus_Support] warning message interpretation



Hello,
It could be that your Pressure Barometric(PB) is input incorrectly or with 
the incorrect units and is several orders of magnitude off.  Typical PB is 
99500.0 BAROMETRIC PRESSURE (N/M**2) with typical values of the Dew Point 
around ~2000(N/M**2).  When I see an input pressure of 0.95 and 1.07 some 
pressure in your input or weather file seems to be way too low.  You will 
need to check that first and see if that is the problem or not.

Thanks Richard Liesen
