EnergyPlus Starting coordinate setup for adiabatic ceiling and floor

edit

Look up the overview and examples here. By default, EnergyPlus relies on a counterclockwise sequential vertex entry convention, when looking at a surface from outside its parent space/zone. A rectangular, adiabatic floor could thus be:

BuildingSurface:Detailed,
    Z1:Floor,    !- Base Surface Name
    Floor, Slab, !- Class and Construction Name
    ZONE1,       !- Zone
    Adiabatic,,  !- Outside Boundary Condition  and Target (if applicable)
    NoSun,       !- Solar Exposure
    NoWind,      !- Wind Exposure
    0,           !- VF to Ground
    4,           !- Rectangle
    9.0,  9.0,  0.0,
    9.0,  0.0,  0.0,
    0.0,  0.0,  0.0,
    0.0,  9.0,  0.0;

If such a rectangular space/zone is not fully enclosed with other surfaces (at a minimum, 4x walls + 1x ceiling), then its ceiling height & volume should be defined explicitly.
