How do you modify the site surface ground temperature in EnergyPlus
In the IDF Editor, you can modify the Site Ground Temperature, Site Deep Ground Temperature, and the Site Simple Factor Model Ground Temperature. How do you modify the Site Surface Ground Temperature?
My outputs show the Site Surface Ground Temperature as being a constant 13C for all months of the year. I would like to model if possible the ground heat flow to the undisturbed site surface ground temperature.
