[EnergyPlus_Support] ASHRAE 90.1 U-factor with or without surface film



ASHRAE 90.1-2007 Table 5.5-3 require that U-value of exterior wall shall be 0.272 W/m2-K.  E+ provides U-values with and without film.  Which one should match 0.272?  We think it should be the U-value without film.  Are we right?

Thanks!
