Hello to all, I would like to know how to model a (closed) shading where I can set the proportion of direct and diffuse global radiation regarding the total solar heat gain coefficient (SHGC) as well as the convective component of the (SHGC)

In addition, is there an option how OpenStudio or EnergyPlus considers the shading and the window as one component, where the shading is still considered only at a certain minimum global irradiance (e.g. 100 W/m²)?

Thanks in advance for any hints, comments, and ideas! Kind regards, Maria
