ERROR: Surface Openings have too much area for base surface

I had developed a model for OpenStudio in SketchUp. On running the OpenStudio simulation, the following errors cropped up.

* Severe * GetHTSubSurfaceData: Surface Openings have too much area for base surface=SURFACE 10 * ~~~ * Opening Surface creating error=SUB SURFACE 5 * Severe * GetHTSubSurfaceData: Surface Openings have too much area for base surface=SURFACE 10 * ~~~ * Opening Surface creating error=SUB SURFACE 6 * Severe * GetHTSubSurfaceData: Surface Openings have too much area for base surface=SURFACE 10 * ~~~ * Opening Surface creating error=SUB SURFACE 7 * Severe * GetHTSubSurfaceData: Surface Openings have too much area for base surface=SURFACE 10 * ~~~ * Opening Surface creating error=SUB SURFACE 8 * Severe * GetSurfaceData: Zero or negative surface area[-19.83093], Surface=SURFACE 10

Note: Here SURFACE 10 is a Wall and SUB SURFACE 5,6,7 and 8 are FENESTRATIONS (doors and windows). The model looks fine in SketchUp, with the Subsurfaces comfortably sitting on the Surface 10. Pls help.

Thanks
