7 Jali The outer skin sits 4 feet away from the building and reduces the direct heat gain through fenestrations, yet allowing for diffused daylight. The jaali thus, serves the function of 3 filters- air, light, and privacy. PEARL ACADEMY OF FASHION, Jaipur courtyards PEARL ACADEMY OF FASHION, Jaipur
