With a growing emphasis on energy-efficient design and occupant comfort, architectural features such as brise soleil are increasingly being adopted in both commercial and residential projects. These systems provide far more than aesthetic value; in addition, they provide practical, long-term benefits in managing solar gain and improving interior environments.
Enhancing energy performance and occupant comfort
Brise soleil, a term derived from French meaning ‘sun breaker’, refers to external shading systems typically made from horizontal or vertical fins. These systems are designed to block direct sunlight while still allowing natural light into the building, helping to regulate internal temperatures without relying solely on mechanical cooling systems.
By reducing the need for artificial cooling during the warmer months, brise soleil systems contribute to lower energy consumption and help buildings meet environmental performance standards. This is particularly beneficial in glazed buildings, where excessive solar gain can lead to uncomfortable heat levels and glare. Shading systems of this nature can also improve workplace productivity and occupant wellbeing by providing a more stable and comfortable indoor climate.
Solar protection and sustainability
In addition to improving thermal performance, brise soleil systems offer passive solar protection that can support broader sustainability goals. When carefully designed, these features can reduce a building’s carbon footprint over time by decreasing dependency on air conditioning.
Furthermore, solar shading helps protect interiors from UV damage, prolonging the life of furnishings and reducing occupants’ exposure to harmful rays. The importance of limiting UV exposure, even indoors, is widely acknowledged, with organisations such as Cancer Research UK advocating for sun safety, offering advice on how to stay safe in the sun, and the effects of prolonged exposure to the sun.
Modern shading systems are available in a variety of materials and configurations to suit different design and performance requirements. Options from providers such as alusystems.uk/brise-soleil-solar-shading can be integrated seamlessly into both new-build and retrofit projects.
Whether the goal is to improve energy performance, reduce solar glare, or enhance architectural expression, brise soleil systems present a practical and effective solution for controlling solar impact in the built environment.
