Passive solar design Indirect/diffused light Sun light brings heat and haze with it. To maximize daylight (intensity of illumination) and to diffuse heat and glare, the light is received in indirect manner by diffusing it. There are three ways by which natural light is drawn within. By upper-level large openings towards north direction, which is cool, and consistent light is reflected off the clouds Skylights, which are projected masses from the roof, reflect the light on the white inner wall surface, which further radiates light into the room Innermost spaces are lit up through small cutouts in the roof slab, which are then filled with hollow glass blocks that take away the glare and transmit diffused light
