The short answer- you can’t because EnergyPlus calculates 1D heat transfer. To include a wall with materials in parallel you have following options:
• Make a single wall with an equivalent R - with the weighted average of the 2 walls.
• Make 2 different walls using sub surfaces. Basically you draw a wall and then draw on it sub surfaces with different layers. More details here about sub surfaces.
