You can create custom constructions with the following layers. You will need to adjust the thickness of the insulation layers slightly to achieve the exact U-factor (inverse of overall R-value), but here is a good starting point:
Roof (see A2.2.1): Built-up roofing, Polystyrene 4 in (R-5/in)
Walls (see A3.3.1): 1" Stucco, 2 in Polystyrene, create a material based on resistance with a R-value of 6.0 to represent the effective R-value of the steel studs plus batt insulation (Table A3.3), 5/8 in gypsum wall board.
See attached for 90.1-2007 baseline roof and steel-framed wall constructions for all zones, compiled with layers per Appendix A and materials per ASHRAE Fundamentals (open the .inp for further info).
File ? Import once you're in detailed mode, reassign surface constructions as necessary.
