Quick Answer
Clerestory refers to a wall section with windows, positioned high above a roof. This ingenious architectural feature is fascinating because it floods large buildings with natural light and ventilation, banishing gloom. It also creates a stunning visual effect, making roofs seem to float and lending an awe-inspiring quality to the interior space.
In a hurry? TL;DR
- 1Clerestory: High wall windows above eye level, designed to bring natural light and air into buildings.
- 2Historically, clerestories lit vast interior spaces in ancient structures like cathedrals before electricity.
- 3Modern uses include sustainable design for passive solar heating/cooling and privacy while maximizing light.
- 4Creates a 'floating roof' visual effect and illuminates deep or central building areas effectively.
- 5Provides privacy from ground-level views while still allowing ample natural illumination.
- 6Consider clerestories for natural light and improved building atmosphere without compromising privacy.
Why It Matters
This architectural feature, the clerestory, is surprisingly clever in its use of high windows to both light and ventilate buildings, creating a sense of spaciousness without compromising privacy.
A clerestory is a high section of wall that contains windows above eye level, designed to flood the interior of a building with natural light and fresh air.
Why It Matters: Understanding the clerestory changes how you perceive the weight and light of the buildings you inhabit.
Clerestory: The Technical Profile Part of Speech: Noun Pronunciation: KLEER-stawr-ee (/ˈklɪərˌstɔːri/) Definition: An upper portion of a wall, containing windows, which rises above the roof of an adjoining lower story.
Lighting the Void The clerestory is the architectural solution to the problem of the deep interior. In massive structures like Roman basilicas or Gothic cathedrals, the central aisles were often too wide for light from the peripheral walls to reach the middle. By raising the central roof higher than the side aisles, architects created a vertical gap where windows could be inserted.
In contrast to standard eye-level windows, a clerestory provides privacy without sacrificing illumination. This makes the feature a favourite in modern residential architecture. It allows a homeowner to bring in the midday sun while blocking the view of a neighbouring fence or a busy road.
According to architectural historians at the Royal Institute of British Architects, the clerestory reached its aesthetic zenith in the medieval period. However, its functional roots are far older, appearing in the Great Hypostyle Hall of Karnak in ancient Egypt. There, massive stone grilles allowed light to filter into the colossal forest of columns, proving that the need for well-lit public spaces is a universal constant of human design.
Examples of Usage
- The architect installed a continuous clerestory along the southern facade to harvest thermal energy during the winter.
- Dust motes danced in the long shafts of light pouring through the cathedral clerestory.
- Rather than adding a skylight, they opted for a clerestory to maintain the structural integrity of the mountain cabin.
Related Concepts Synonyns: High-level window, monitor roof, overstory. Antonyms: Basement window, cellar light, ground-level glazing.
Usage Tips
- Distinction: Do not confuse a clerestory with a skylight; a clerestory is always part of a vertical wall, whereas a skylight is set into the horizontal or sloped plane of the roof.
- Adjectival Use: You can use it as a modifier, such as clerestory lighting or a clerestory window.
