Yi,
For Type 56 geometric information of a window surface orientation as slope isn’t mandatory. You can define a model
where the geometric information is given by the surface area and the incident angle of the beam radiation.
The slope defined in the window type manager is used for calculating the convection of gaps between glass panes for all windows.
(The slope of the surface given by a standard orientation is NOT used.) For solar radiation calculation the angles of the orientation
are used.
Best regards,
Marion

Dear Yi,
a normal window (in the facade) has a slope of 90 degrees. That means it`s vertical. The slope is the inclination. In some projects the slope of windows is varied in order to e.g. avoid some solar gains.
I hope, this helps you.
Best regards
Margarethe

Betreff: [TRNSYS-users] in TRNBuild, what does the "slope of window" in window type manager mean?
hello trnsys-users,
i can not undetstand, why there is a slope difinition in the window type. slope means something about orientation. but the orientation is already descript in zone definition, isn't it? or it means each different slope should be a window type, even if everything else are same?
and I built a simple modell in sketchup with trnsys3d. when i look deeper, in the idf and b17 file, every window type has the same slope 90.
i'm a little confused.regards
Yi
