Brise soleil

A basic brise soleil at the Charles Wells Brewery for Wells & Co. This photo was taken of the south facing elevation at noon in December, a little before the Winter Solstice. Note how all the windows are in the shade.

Brise soleil, sometimes brise-soleil (French: [bʁiz sɔlɛj]; lit. '"sun breaker"'), is an architectural feature of a building that reduces heat gain within that building by deflecting sunlight.[1] The system allows low-level sun to enter a building in the mornings, evenings and during winter but cuts out direct light during summer.[2]
