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.

The value improved productivity and healthier built environments is intangible,

But is perhaps the most significant benefit of Green Architecture.

Good design doesn’t cost,

but it pays.

Design adds value faster

than the cost.
