I am using OpenStudio 1.11.1 and energyplus version is 8-5-0.

my building consists of single story with attic, and I am not using ideal load or HVAC system, after I run the simulation I get 26 errors:

19 errors due to surface matching even the sketchup didn't show any errors after surface matching: (I used matching tool and intersections for matching), however I noticed that all the errors are due to surface matching between the interior ceiling and the attic floor.

and 7 other errors as shown in following figure:

Be great if you could paste your errors instead of using a picture in the future please!

Anyways, the reason why it fails to run is because you have surfaces that end up without a construction (I'd look at the default construction template you have set for your building...), one construction that doesn't appear to have any "Materials" assigned to it, and a a ZoneInfiltration:DesignFlowRate that is missing a schedule. All these should be easy to fix.

As far as your surface matching construction errors, open the model in sketchup and use the search tool to find both "Surface 388" and "Surface 377" and look at if they are correctly matched, and whether you have hard assigned constructions to them.

thanks for your help
@Julien Marrec i already fixed most of these errors and the last 4 errors i couldn't solve it, could you please help me on them:

Like I said, this one is because the construction "Interior Ceiling" doesn't have any Materials assigned to it. You can view it in OpenStudio, on the Construction's tab (the 2nd), find this construction, and assign at least one material (=Layer) to it.

@Julien Marrec i assign Materials for Interior Ceiling (Note that: im not using the Interior Ceiling construction in my building) but that give me more errors:
