I was wondering how I might be able to calculate the total heat capacity for a house given the individual heat capacities of the components.
For example, if I take a given wall and break it down into its components for a lumped parameter model, I'll have some thermal capacitances in in parallel. In the circuit analogy, they would be drawn as capacitors. Do these add like capacitors in a circuit would (algebraically for parallel, inversely for series)? I don't imagine I'd have any capacitances in series because each component has an RC pair in parallel...
I realize that a lumped parameter model is not realistic for a wall (the Biot # would be huge), however I'm more interested in the differential equations application of this.
Thanks.
