NC-2009 EAp2: Minimum Energy Performance
I have wall assemblies with no cavity insulation but 3-4 inches rigid insulation outboard of structural sheathing. The wall is finished by a composite metal panel. Do I have to consider ASHRAE appendix A for such an assembly? I would imagine the thermal bridging effects of the studs would be very minimal in such an assembly.

You should always use Appendix A to determine the assembly performance.
