how can i make empty space type for attic? I'm using openstudio 1.11.1 and my model is a single story office building with a hipped roof and the building has ceiling split it from the attic, where the attic is non conditioned . So for this case what type of space type for the attic can I choose? If I want to assign empty space type for the attic, how can choose empty space since it is not available in the library? For your information "get BCL space type" is not available in this version. Thanks in advanced.
