Wind Loads on Screen Porch Addition

[mveng]

Hi,
I am designing a screen porch addition, and am trying to determine the wind pressure on the walls. Is there a design guideline for wind on screen walls based on ASCE 7-10/IRC 2015?

Thanks!

Not screens other than "lattices". We usually assume the screen as solid since the drag on all the screen wires can be significant and in the future windows could be added, banners attached, plastic sheets flying in the wind might slap onto the screen, etc.
