modelSlab
Slab below the experimental house
Extends from BondLib.Interfaces.ActiveOnePort (Partial model invoking one bondgraphic connector).
Information
In Tucson, houses are built on sand. The house is not thermally insulated from the ground, thus, the thermal building model ought to take into account the exchange of heat between the house and the slab underneath it.The slab is modeled with a single conduction layer connecting the temperature of the slab to the temperature of the floor. Above the floor, there is a boundary convection layer.
