Chajja
The projecting external sunshade over an Indian window or door — vernacular climate design that keeps direct sun off the glass while still letting bright, bounced daylight in. The key to the Indian Extend trade-off: separate the light you want from the heat you don't.
Light in, sun off the glass
A chajja lets you keep a generous window for borrowed light without baking the room behind it. Prefer cool north light, shade the harsh south and west — brightness in, heat out.
