Create EP Ground

Use this component to change the properties of a zone to refelct those of a ground. This is particularly useful for setting up outdoor thermal comfort maps when you want the surface temperature of the ground to be caclated with some spatial diversity, reflecting the shadows that other objects cast upon it and the storage of heat in the ground surface.
The turning of a zone into a ground zone entails...
1) Setting all constructions to be indicative of a certain soil type (see the _soilTypeOrMat description for more information).
2) Setting all surfaces except the roof to have the boundary condition of 'ground', including no sun or wind exposure for these surfaces.
3) Getting rid of all loads and schedules within the zone.
All values for soil type are taken from the Engineering Toolbox, specifically these pages below...
