Does anyone know the ICC requirement for the amount of plywood sheathing required per linear foot of 8' wall?

I am building a 18' X 20' addition with three free sides. I was planning to put very large windows and patio doors in. I know there is some rule for the square footage of plywood per linear foot of wall, but I can't find it anywhere on the web.

This is a single story (8' high} room with 3-4'6" X 5' windows in the back wall, a 6' X 6'8" French Patio door and two 5' X 5' windows in one of the 20' sides and two 6' X 5' windows plus a standard 3' X 6'8" door in the other 20' side.
