Re: [EnergyPlus_Support] ground temperature



My mistake, CalcSoilSurfTemp is for generating parameters specific to EarthTube simulations.  You can use the Slab pre-processor to predict the ground temperature.  See the Auxiliary Programs documentation for more information.

I'm guessing you are saying that your DesignBuilder model used the default of 18 degrees for all year for the ground temperature.  You can enter monthly measured or assumed values in the Site:GroundTemperature:BuildingSurface object.  You can get a better approximation of these values if you use the CalcSoilSurfTemp utility.

hello everyone
i am facing a problem in defining in ground temperature because when i export idf file from design builder in takes 18 degree C for all the 12 months as default value for my climate condition. however i change this value by monthly dry bulb temperature i don't know that this methodology is correct or not. So plz can anybody can tell me that i am doing the right thing or not and tell me the better way for ground temperature.
