Specific and scattered thermal bridges are very difficult to model in a commercial building. Broad and general thermal bridges, like steel studs, should be modeled. Determining the envelope U values in 90.1 should follow Appendix A. Quite often LEED projects report the U value directly through the insulation and do not de-rate these envelope components properly.
