When modeling Residential Projects, you are required to include a Floor, 4 walls and a Ceiling/Roof. This zone has an incorrect Ceiling/Roof area that does not match the Floor Area of the Zone.
Start by reviewing ALL surfaces in this zone, including Interior Surfaces to be sure they are input as the correct Assembly type (ie roof, floor, wall, etc.)
Look at zones that are adjacent to this one, to ensure you do not have a floor that is input as Interior and Adjacent to this zone. You should not input these surfaces twice (as a floor above and a ceiling below).
