Brise soleil, sometimes brise-soleil ({{IPA|fr|bʁiz sɔlɛj|lang}}; {{literal translation|sun breaker}}), is an architectural feature of a building that reduces its heat gain by deflecting incoming sunlight.{{cite book |title=Matter: Material Processes in Architectural Production |publisher=Routledge |year=2012 |page=330 |editor1-last=Borden |editor-first1=Gail Peter |editor2-last=Meredith |editor2-first=Michael}} The system allows low-level sunlight to enter a building in the mornings, evenings and during winter but cuts out direct light during summer.{{cite journal |title=Brise Soleil |journal=Two Point Seven Facades |date=2019 |volume=1 |issue=1 |url=https://twopointseven.co.uk/blog/f/brise-soleil |access-date=11 July 2020}}

Types

Brise-soleil can comprise a variety of permanent sun-shading structures, ranging from the simple patterned concrete walls popularized by Le Corbusier in the Palace of Assembly{{Cite web |date=2011-08-10 |title=AD Classics: Palace of the Assembly / Le Corbusier |url=https://www.archdaily.com/155922/ad-classics-ad-classics-palace-of-the-assembly-le-corbusier |access-date=2023-02-13 |website=ArchDaily |language=en-US}} to the elaborate wing-like mechanism devised by Santiago Calatrava for the Milwaukee Art Museum{{Cite web |last=Museum |first=Milwaukee Art |title=Burke Brise Soleil {{!}} Milwaukee Art Museum |url=https://mam.org/visit/burke-brise-soleil/ |access-date=2023-02-13 |website=mam.org}} or the mechanical, pattern-creating devices of the Institut du Monde Arabe by Jean Nouvel.{{Cite web |date=2011-10-02 |title=AD Classics: Institut du Monde Arabe / Enrique Jan + Jean Nouvel + Architecture-Studio |url=https://www.archdaily.com/162101/ad-classics-institut-du-monde-arabe-jean-nouvel |access-date=2023-02-13 |website=ArchDaily |language=en-US}}

In the typical form, a horizontal projection extends from the sunside facade of a building. This is most commonly used to prevent facades with a large amount of glass from overheating during the summer. Often louvers are incorporated into the shade to prevent the high-angle summer sun falling on the facade, but also to allow the low-angle winter sun to provide some passive solar heating.{{Cite book|title = Dictionary of Construction Terms|last = Tolson|first = Simon|publisher = CRC Press|year = 2014|isbn = 9781317912354|pages = 40|url = https://books.google.com/books?id=JPVfAwAAQBAJ&q=brise+soleil&pg=PA40}}
