This model modifies the default implementation of the window to
be more in line with EN673. E.g. the exterior and interior total
convective heat transfer coefficients are changed. The resulting
U-value is computed as U_EN673 and can be compared to
the default implementation U_default. The interior air
cavity heat transfer coefficient computations are unchanged, which
explains the different results with the standard.
This model can be used to verify that U_EN673 is
sufficiently close to the expect U value of the glazing system.
When this is not the case, you likely made an implementation error
with the coating (= long wave emissivity) implementation.
Furthermore, this model can be used to check what the wind speed
and temperature-dependent U-value is.
