Modeling constant convection coefficients on interzonal surfaces in EnergyPlus

JMaguire's avatar

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?

Only the inside face heat balance is modeled for an interzone surface, so It should be adequate to specify just the interior convection coefficients. But it would be an interesting test to specify something wildly different for the outside convection coefficients and see if the results change (they should not change).
