Ways to add shading device on windows

I want to add horizontal and vertical shading to windows for energy calculation. I have used Add subface component to add windows. To add shade I am using HB add shade. However, my simulation is taking more than 12 hours to run. I have attached the workflow of the aperture and shade I have used.
Is there any issue with it ? I have run my model without shade and it ran within 5 min. But after adding shade it is taking 1 day to run.
