I have a simulation to perform in OpenStudio in which the model has external shading devices that respond to the Sun's position. Is there a method to define dynamic shading devices, preferably two-axis tracking or something similar? I heard that there is EMS for OpenStudio API, is it possible to execute such kind of dynamic shadings simulation offering approximately a similar results? If there is not a way to do so, what should I do to obtain acceptable results of shading performance?
