[EnergyPlus_Support] "U-Factor no Film" vs "U-Factor with Film"

[Nuno Costa Brandão <ncostab@xxxxxxxxx>]

Hi All,

I made a "hand calculation" and I verified that the values for surface
transfer coefficients(U in W/m2-K) presented by EPlus in a simulation,
do not account for the surface resistances.
The U values presented in the "Envelope Summary" do not correspond to
the ones that I defined in DesignBuilder for the simulation. Does the
"U-Factor no Film
(W/m2-K)" account for "Interior and Exterior air surface resistances"?
If not, how can I bring these values to the "Envelope Summary" report?
Is it the "U-Factor with Film"? This column appears in the report but
its empty... Can anyone help with this issue?

Thanks for the help
Nuno
