Kiva error simulation EnergyPlus
I'm trying to simulate Kiva with EnergyPlus, but the next error continues to come out.
** Severe ** Foundation:Kiva="<Default Foundation>", only one floor per Foundation:Kiva Object allowed.
What this is mean? Im quite new in simulation with EnergyPLus and Kiva but i need to calculate the ground surface temperature. Somebody can help me?
