[EnergyPlus_Support] Re: DesignBuilder to EnergyPlus errors

["anarui.oliveira" <anarui.oliveira@xxxxxxxxx>]

Hi again.

I seem to have solved the problem by re-locating the windows (in the 
DesignBuilder) ABOVE the height that would correspond to the defined 
floor construction. I can't really be sure that this is the key 
difference to previous attempts, since I rebuilt those blocks from 
scratch, but it may be a useful tip for future reference.

Regards,
Ana Rui.
