[EnergyPlus_Support] Construction:FfactorGroundFloor Question

[Jacob Dunn <arch.dunn@xxxxxxxxx>]

Dear EPSG - 

I have a quick question about the "Construction:FfactorGroundFloor" object in EnergyPlus.  The third and fourth input field asks for the area of the slab on grade floor and the amount of exposed perimeter.  

My question is this:  do I input these values for the surface (assuming the floor is divided into multiple surfaces due to thermal zoning), or for the entire floor?  The inputoutreference specifically says "of the slab-on-grade or underground floor."      

The only example file that has this object is a one continuous zone model, so it does not provide any direction on the issue.

Cheers and thanks!
