Buildings.BoundaryConditions.GroundTemperature.Examples.CorrectedConvection
Example model for undisturbed soil temperature with surface convection correction
Information
This example model showcases the use of the convection coefficient correction, which allows to specify the heat transfer rate between the air and the surface temperature.

Buildings.BoundaryConditions.GroundTemperature.Examples.CorrectedNFactors
Example model for undisturbed soil temperature with n-factors correction
Information
This example model showcases the use of n-factors, which are used to correct the surface temperature given the ratio of freezing/thawing degree days (FDD/TDD) between the air and the ground.
References
The values used in this example are equivalent to the use-case presented in the "Heat Transfer at Ground Surface" section of the District Cooling Guide (ASHRAE, 2013).

Buildings.BoundaryConditions.GroundTemperature.Examples.UndisturbedSoilTemperature
Example model for undisturbed soil temperature
Information
This example model illustrates how the undisturbed soil temperature model decreases seasonal temperature oscillations and increases delay as depth is increasing.
