I took the example files for the kiva objects, ZoneCoupledKivaSlab.idf and ZoneCoupledKivaBasement.idf, and changed the Site:Location, SizingPeriod:DesignDay objects, and weather file for each of the CA climate zones. There are some strange errors for the "autocalculated deep ground depth" in some of the simulations. Obviously, something is wrong. Here is a google drive link to the files.
I'll report this as a bug on github, but my question right now is: Is there a field in Energyplus I can use to override the faulty behavior?
ZoneCoupledKivaSlab.idf
Foundation:Kiva="SLAB FOUNDATION", the autocalculated deep ground depth (1.328 m) is shallower than foundation construction elements (1.500 m)
Foundation:Kiva="SLAB FOUNDATION", the autocalculated deep ground depth (-0.919 m) is shallower than foundation construction elements (1.500 m)
ZoneCoupledKivaBasement.idf
Foundation:Kiva="BASEMENT FOUNDATION", the autocalculated deep ground depth (1.328 m) is shallower than foundation construction elements (3.425 m)
Foundation:Kiva="BASEMENT FOUNDATION", the autocalculated deep ground depth (3.883 m) is shallower than foundation construction elements (3.425 m)
