I am wondering what is the most accurate way to model a concrete-reinforced high-rise in BeOpt2.8.
The building is a high-rise in IECC climate zone 1 (Hawaii). We can assume that the minimum designed wall insulation is R-13 when looking at the HI commercial energy code. However, I am not sure if the proper way to model this is by selecting an R-13 option under Walls>Steel Stud or from some other option. I am an Energy Engineer and have limited Structural Engineering understanding. Thanks for your help!

The steel stud options do not have any concrete; they represent steel framing, not steel rebar inside concrete.
 
It's possible that existing options in BEopt in e.g. the CMU or "Other" category are a close approximation of this construction type. Alternatively, you could model the construction in the THERM Software, calculate the effective conductivity, and then enter it (and other properties) as a new custom option in the "Other" category.
