Internal courtyard houses

The summer portion:

This part works in the summer, gaining the least sunshine, with a wind catcher and a Kollah Farangi (a space with dome roof and vents on the dome) also a Talar.

Talar:

The Talar is a three sided wall space directed to the north-east, it reserves cool in its walls, roof, and floor during the night, and gives it back during the day. Not receiving any direct sun, it does not gain very much heat during the day. Its roof has two layers of mud-brick with an air space to insulate the roof. The wind catcher and the Kollah Farangi are both located in a room that is situated in the corner of the courtyard where there is no heat gain from the sun. The wind catcher catches the cool breezes and leads them into the room, and Kollah Farangi sucks the hot air out of the room. The function is the same as described above for Dowlatabad building.
