What do you mean by kinetic shading device? What should it do how should it look?
Have you seen this (link below) if not take a look. I am sure it will help. One of the last ones is on solar analysis.
I mean in base of the sun it closes and opens similar to the albahar tower concept.
My advice: Go back and study the Dynamo Primer as this exercise (adjusting something based on the angle of the sun) is well documented there.
