Modeling constant convection coefficients on interzonal surfaces in EnergyPlus

edit

I have a situation where I'd like to apply constant convection coefficients to all of the surfaces in my model using the SurfaceProperty:ConvectionCoefficients:MultipleSurface object. The building two adjacent zones (a crawlspace and a living space). When I specify the convection coefficients for "AllInteriorFloors", should I only specify the inside convection coefficient as the convection coefficient I'd like to use for the floor, or should I also specify an outside convection coefficient using the value I'd like to use on interior ceilings?
