There are all sorts of windows that an architect might select for a building.
Chicago Window
A grouping of 3 windows, where there are two double hung windows on the sides of a picture window. These windows were used way back when in Chicago, in buildings like The Marquette Building, one of the earliest skyscrapers built. Chicago windows allow for great expanses of light, while also having the two side windows that open to allow fresh air to flow through. You get the best of both worlds with Chicago Windows – light and air.
