EnergyPlus building geometry Errors

Hi,

 I am troubleshooting Energyplus building geometry errors and advise on overall approach am taking with the geometry to debug and fix the errors and warning.  I have had such warnings before in prior projects but non severe ones. Has anyone come across these severe errors?
