windows in a load bearing wall
2 story, 1 story, wood sheathed walls, wall length, percentage of glass to floor area, proper type of glazing required for certain areas, enough footage of shear left in the wall, codes for closeness to power lines, energy codes followed to possibly compensate for large amounts of glazing. Window guard in certain conditions. Possible egress conditions.
Special requirements for certain States (internal pressure, high wind areas).
I hope you ask your local Building Department for their recommendations and approval. Be safe, G
