kiva autocalculated deep ground depth is negative

[mldichter]

Issue overview

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.

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)

Foundation:Kiva="BASEMENT FOUNDATION", the autocalculated deep ground depth (-0.919 m) is shallower than foundation construction elements (3.425 m)

This is intended behavior. See my response on Unmet Hours.

The warning message should be changed, and we should add a warning if both autocalculate and a deep ground temperature are selected (see comments in Unmet Hours).
