This is a trial to see if the sunshades auto extend and auto rotate to the suns angle to get the maximum shading. The angle is alway kept perpendicular to the sun. while the extension is kept from 0 to a maximum length of the height. Meaning to say of H is the height of 1 facade, then the length of facade L =< h ="0," l ="o.56H," l =" 0.99H."> Feel free to crit on this post
