Re: [EnergyPlus_Support] Anomalous results with ** Warning ** GetAirPathData: & ** Warning ** WetBulb
If you don't have another machine to run it on, send me the idf privately.

Hi Marco,
Do a text compare of the in.idf file located in the DesignBuilder energyplus folder, and the exported idf. They should be the same. If not, I would notify DesignBuilder via a helpdesk ticket. Let me know what you find.
