Q. The solar protection system consisting of fixed slats or grids, outside a building façade in front of openings, is known as
(A) Brise–soleil
(B) Solarium
(C) Malqaf
(D) Trombe wall
Ans: Brise–soleil
Explanation: Brise soleil, sometimes brise-soleil, meaning a ‘sun-breaker’, is an architectural feature of a building that reduces heat gain within that building by deflecting sunlight. Malqaf is a wind tower or a wind catcher in traditional Iranian ar chit lecture. The solarium is a room fitted with extensive areas of glass to admit sunlight. A Trombe wall is a passive solar building design where a wall is built on the winter sun side of a building with a glass external layer and a high heat capacity internal layer separated by a layer of air.
