How do I model a High Performance Attic as described in the 2016 Standards?

Select an Attic roof assembly that has the appropriate level of ceiling insulation in the EnergyPro Assembly library.  For a high performance attic with above deck insulation (option A) edit the input for “Above Deck Insulation” (or if doing Prescriptive compliance “Exterior Insulation”) and put in an R-Value of 6 or 8 (or any other value you wish).  For a high performance attic with below deck insulation (option B) edit the input for “Below Deck Insulation” (or if doing Prescriptive compliance “Interior Insulation”) and put in an R-Value of 13 or 18 (or any other value you wish).

If you do the option B approach, including a radiant barrier is not needed since the insulation will be up against the barrier and will negate the product effectiveness.
