how can I fix this error in design builder file?
I am PhD student, I use design builder program to study indoor thermal comfort, the case study file which I modeled wasn't simulate completely, and there were error message, I need to know what are the right steps to can fix this file. the error massage :

** Warning ** ManageSizing: For a zone sizing run, there must be at least 1 Sizing:Zone input object. SimulationControl Zone Sizing option ignored.
** Warning ** Site:GroundTemperature:BuildingSurface: Some values fall outside the range of 15-25C.
** ~~~ ** These values may be inappropriate. Please consult the Input Output Reference for more details.
** Warning ** CalcSurfaceCentroid: 8 Surfaces have the Z coordinate < 0.
** ~~~ ** ...in any calculations, Wind Speed will be 0.0 for these surfaces.
** ~~~ ** ...in any calculations, Outside temperatures will be the outside temperature + 9.750E-003 for these surfaces.
** ~~~ ** ...that is, these surfaces will have conditions as though at ground level.
** Warning ** GetSurfaceData: There are 9 window/glass door(s) that may cause inaccurate shadowing due to Solar Distribution.
** ~~~ ** For explicit details on each window, use Output:Diagnostics,DisplayExtraWarnings;
** Warning ** CalculateZoneVolume: 5 zones are not fully enclosed. For more details use: Output:Diagnostics,DisplayExtrawarnings;
