Latticed Screen / Jaali at the Sabz Burj, Nizamuddin (views inside and outside). Cut the glare and yet illuminate the space. Cut the gaze yet maintain the aperture view. Cut the heat and humidity and yet let the breeze filter in and cool the high-ceiling space. When the air passes through a drilled pattern of the jaali its velocity increases thus improving the cooling efficacy. And the geometric pattern creates a lovely play of light and shade inside.
