Ground Domain - Soil

Soil tab on Ground Domain Dialog

 

On this tab you can select the Material defining the ground thermal properties and enter moisture content of the ground. The thermal properties of the material are used in calculation of the undisturbed ground temperatures as well as general heat conduction from building ground-adjacent surfaces connected to the ground domain object.

Soil Thermal Properties

Soil material

Select the material used to define the soil thermal properties.

Soil Moisture Content

Moisture and freezing effects are accounted for within EnergyPlus during the simulation by varying the specific heat value.

Soil moisture content volume fraction

A nominal value of soil moisture content to be used when evaluating soil thermal properties.

Soil moisture content volume fraction at saturation

A nominal value of soil moisture content when the soil is saturated, this is used in evaluating thermal properties of freezing soil.
