You're currently asking what's the difference between two different things. Grasshopper is a graphical algorithm editor for Rhino. It doesn't do glazing modeling. Some plugins exists, including some based on energyplus (ladybug/honeybee). Which one are you referring to?

my work is with accumulating between electrochromic glazing with dynamic horizontal and vertical shading with wide more than 1 meter, I used energy plus, but I was asking if there is another simulation program may be more efficient with dynamic shading ???
