In planning for windows, consider the use of large glass areas not only in the living room but also in any room of the house that can benefit from increased daylight, view, or heat gain from the sun. On the other hand, small window areas may serve several purposes well. A bedroom on a western exposure for example may employ a series of short, high windows that supply daylight, provide privacy and yet keep the glass area on this exposure to a minimum so that the rays of the sun are not objectionable.
Often a combination of window types is best suited for both interior requirements and exterior appearances. The use of fixed glass with one or more operating window units achieves a functional window that also has a pleasing architectural character. Such units permit:
- The head of the window to be placed high in the wall for daylight.
- The sill of the opening section of the window to be placed low in the wall - the best location for natural air movement.
- The middle half of the wall to be left unobstructed for views.
