[EnergyPlus_Support] Re: Error explanation needed

["FrancescoP" <direzionecontraria@xxxxxxxx>]

Hello,
I got the following warning:

** Warning ** WriteVeriSumTable: InputVerificationsAndResultsSummary: Wall area based on [>=60,<=120] degrees (tilt) as walls
   **   ~~~   ** differs ~5.9% from user entered Wall class surfaces. Degree calculation based on ASHRAE 90.1 wall definitions.
   **   ~~~   ** Calculated based on degrees=[2604.855] m2, Calculated from user entered Wall class surfaces=[2460.135] m2.
   **   ~~~   ** Check classes of surfaces and tilts for discrepancies.

All the walls of my model should be vertical.
Is all the relative information available in the .eio file? I checked there but all the walls seem to have an inclination of 90 degree. Actually, the walls are a lot. Perhaps I didn't see the walls that are not considered vertical. What is the quickest way to see which surfaces generate the warning?
Best Regards
Francesco Passerini
