This Excel workbook sets up equivalent network analogs both for steady-state conduction heat transfer and for radiative transport using the radiosity method for diffuse-gray surfaces.  

Several numerical examples from both conduction and radiative transfer are included in this workbook.    One involves a model for conduction heat transfer in a convectional stud-wall construction.   Another analyzes the value of painting the underside of a roof deck with low emissivity paint.  VBA functions are provided so that the user can create a circuit schematic for a network of their own choosing.
