EnergyPlus doesn't have a concept directly of a transparent wall; walls are opaque. So to model a curtain wall make a wall representing your curtain wall and then create a large sub-surface setup as a window that is almost as large as your opaque surface. If you want to get into details about the mullions, there is a Frame and Divider object you can refer to.
