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.
