Oberlichtern

Oberlichtern is a German term that translates to "clerestory" in English. It refers to a window or series of windows placed in the upper part of a wall, typically above the main roofline or higher than the surrounding windows. These windows are designed to admit light into a building or space from a high level. Historically, clerestory windows were a common feature in religious architecture, such as churches and cathedrals, where they allowed natural light to illuminate the nave and altar areas, often creating a dramatic and ethereal atmosphere.

In secular architecture, oberlichtern serve a similar purpose, providing natural light and ventilation to interior spaces that might otherwise be dark or poorly lit. They can be found in various types of buildings, including industrial structures, warehouses, public buildings, and even residential homes. The design of oberlichtern can vary greatly, from simple rectangular panes to more complex arched or decorative arrangements. They are often positioned to capture sunlight at different times of the day and year, optimizing illumination and reducing the need for artificial lighting. In some modern applications, oberlichtern may be integrated with advanced glazing technologies to improve thermal performance and energy efficiency.
