Final answer:
Condensation inside double paned windows suggests a seal failure, requiring window replacement. The Chicago window is an architectural feature from the Chicago School, designed for light and ventilation with a fixed center pane and operable side panes.
Step-by-step explanation:
Condensation inside double paned windows indicates that the window has failed and needs to be replaced. Double pane windows, also known as insulating glass units (IGUs), consist of two glass panes separated by a vacuum or gas-filled space to reduce heat transfer. When seals around the IGU fail, moisture can enter the space between the panes, resulting in condensation. This indicates that the insulating qualities of the window are compromised and it's no longer functioning as designed. Windows are critical components of a building's envelope, affecting both the energy efficiency and the comfort of the interior spaces.
The "Chicago window," originating from the Chicago School of architecture, is a notable window design that features a large fixed center panel with two operable double-hung sash windows on each side. It is designed to maximize light-gathering and natural ventilation. The central pane, usually fixed, allows for ample light to enter, while the side panes can be opened for ventilation. This design was a functional and aesthetic response to the need for light and air in tall office buildings during the late 19th and early 20th centuries.
