You have the option to assign a fractional schedule to a shading surface as a transmittance schedule, shown on screenshot below. The use of a schedule vs. just a static transmission fraction allows you to model seasonal variations that you might see from trees.
You could also use a blind material in the window. It has inputs for screen properties. You may also want to look at an earlier post on complex shading.. Using the blind approach will only impact windows, while a large shading surface would also impact sun exposure on the base surface.

As a sneak peak, you will be able to do this in the OpenStudio application in 1.9.0
