New in OpenStudio.

The building area expressed in the OpenStudio results is not representative of the building area in my Sketchup model.

I used the Sketchup plugin to model my building. I then used OpenStudio and added some things here and there. When I run the simulation and I open the OpenStudio Results, the total building area shown is 408 ft^2. My building is much bigger than that.

My Sketchup model is in millimeters and I selected SI units in OpenStudio. However, my units still show up in imperial in the OpenStudio results. Could that be linked?

I appreciate your time!

The EnergyPlus report will always be in SI, and the OpenStudio report in IP. How are you checking the building area in SketchUp, and what is it reporting? I assume you are selecting one more surfaces and using the native SketchUp entity information window?

The first thing I'd look at is that all the spaces you have made in SketchUp are assigned to thermal zones, and that zone doesn't span story.

No we can't link the SketchUp unit preferences to the OpenStudio Application unit preferences. Also the OpenStudio Application unit preferences don't affect reporting measures.
