It then computes the radiation through the wall. Since the wall also radiates to the outside, the radiation model, which computes the balance radiation, requires information of the temperature of the outside of the wall (the 0-junction between the outside convection layer, C1V, and the first conduction layer, C1D. This temperature is sensed using an effort detector, De.
The solar radiation model computes the entropy flow to the wall from both direct and diffuse radiation. This enters the model through a modulated flow source, which is attached to the 0-junction representing the outside of the wall.
The ambient air temperature is also computed inside the model, which is again computationally wasteful. The ambient air temperature is connected by means of a modulated effort source to the outside of the air convection layer. Since the ambient air temperature is simply an observed quantity, rather than a physically computed quantity, no heat capacity is added to that node.
