Area types are an instance property of areas. Area types contain area measurement rules that Revit LT applies to area boundaries.
Area type values come from the default area schemes: Gross Building and Rentable. The Gross Building area scheme has 2 area type values: Gross Building Area, and Exterior Area. The Rentable Area scheme has 6 type values: building common area, office area, exterior area, floor area, major vertical penetration, and store area.
When you create a new area scheme, it uses the type values from the Rentable area scheme.
