Movable exterior shades

Hello all,

I am dealing with an automated moving exterior shade. I was going to use the building shades and apply a schedule to them but I noticed a warning in the type about how it only calculates direct solar for the first day of each month and the same for the diffuse. Does anyone have experience with these type of shading devices and knows of the best possible way to model them? Thank you.

Dear John,

If the moving shade is covering a window, you can use the shading options
under the Blinds/Drapes tab of the window properties. Here you can also
set shading schedules for hourly control.

I understand but the shade is on the exterior of the window. Does a .8 transmittance value correlate directly to the SC * 0.8 ?
