Modeling a Green Roof in Honeybee for Building Energy Performance Analysis

Hello,

I have already tried using the Green Roof component in Honeybee, but I am not sure where exactly it should be connected or assigned within the workflow. I would like to evaluate the impact of a green roof on building energy consumption, but I am having difficulty implementing it correctly in my model.

I am attaching my Grasshopper file for reference. I would greatly appreciate it if you could take a look and let me know what I am doing wrong or where the green roof should be assigned.
