Will the masonry wall insulation change in R-value have an impact on the Florida Energy Code calculation?

Probably not. The change from the standard version of AA2 Vapor Shield and VR Plus Shield to the Hi-Perm version only impacts the R-value by 0.1, so it has little, if any, effect in the overall load on the house. The overall point total should not change. However, the Florida Energy Code Form must indicate the correct R-value for inspection purposes.
