How to Properly Model a Concrete-Reinforced High-Rise with BeOpt2.8
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!
