Thermal model of a House. Simulink and Simscape approaches. From Simscape network to system equations.

Hi everybody,

I am trying to understand the (Simscape) house thermal network from this model: Link1

Is it possible to get from the network the set of equations that define the model? I think it is, but I do not see a clear relationship. As the link1 says, "each path is simulated as a combination of a thermal convection, thermal conduction, and the thermal mass". However, I am not able to "translate" the Simscape network to the equations that define the system.

Basically, what I am trying to do is to get and understand the set of equations that define the house thermal model and to compare the simulink approach vs the Simscape one. In the Simulink case, the set of equations are clearly explained and described in the following link: link2

Best regards,
