I would create a Material object that has the same heat transfer properties (density, specific heat, conductivity) as the soil for your location, then set the thickness to be small (~1") so that EnergyPlus doesn't calculate much heat storage within this artificial soil layer. Then, create a Construction object that references only the name of this artificial soil layer. Finally, reference the name of this Construction object in the BuildingSurface:Detailed object that represents your zone's floor surface.
I did it, But it didn't work. I have simple glassed closed zone with no infiltration or ventilation. So it should be a furnace at noon! but the zone temperature is less than environment ! when I change the floor material I reach the zone high temperature.
here is my model: My Model
Thank you. I did it as you proposed it to me and it worked. I set Outside boundry condition ==> Foundation and I added a new Foundation:Kiva object and SurfaceProperty:ExposedFoundationPerimeter object in order to model ground temperature.
then the answer is accurate.
