Final answer:
The bay windows on the 3rd floor differ in their structure and function, consisting of a three-part arrangement for optimal light and ventilation, and they may project outward as oriel windows.
Step-by-step explanation:
The bay windows on the 3rd floor of the Old Minnehaha County Jail are likely different from the windows on other floors due to their structure and function. Originating from the Chicago window concept, bay windows typically consist of a three-part window arrangement. This design features a large fixed center panel flanked by two smaller double-hung sash windows. These windows serve the dual purpose of providing ample light and enabling natural ventilation. Usually, the central pane is fixed, while the two side panes can be opened for airflow.
Bay windows often project from the facade, forming an oriel that extends over the street. This architectural feature allows for better light and views compared to the simpler, flat windows that may be present on the other floors. The bay windows' unique ability to gather light and facilitate ventilation is particularly suited for communal or significant rooms which require such benefits, possibly making them distinct from windows on lower floors that might have simpler requirements.
