Drehfenster

Drehfenster is a type of window found in traditional European architecture, particularly in Germany and Austria. It is a rotating window that allows for fresh air and ventilation, while also providing a degree of protection from the elements.

The Drehfenster typically consists of two sashes that are connected by hinges, one fixed and one movable. The movable sash is rotated to either side of the fixed sash, allowing for horizontal access rather than the vertical movement associated with more conventional windows. This design provides benefits in terms of ergonomics, as it allows users to access the exterior of the window without having to climb a ladder.

Drehfenster are often found in historic buildings in Germany and Austria, particularly in urban centers such as Vienna and Munich. They have been adopted into modern building design, particularly in countries with rich architectural heritages, and are prized for their aesthetic and functional qualities.

One of the unique features of the Drehfenster is its use of geometry to optimize airflow and sunlight penetration. The rotating sash allows for the admission of air and light at every angle, making Drehfenster particularly well-suited to passive solar architecture and other techniques for reducing the need for artificial lighting and heating.

Today, the Drehfenster continues to be a subject of interest among architects and historians, and is increasingly being incorporated into new residential and commercial buildings, particularly those with a historic or cultural significance. Their unique design and functionality provide a compelling alternative to more conventional window designs.
