TRADITION
 There is a strong belief in that which according to what noble Quran wars the Muslim the territory and privacy of should be respected by the others which can be realized through introvert courtyard houses.  The main characteristic of this architecture are as follows:
 It's hidden - another term is "the architecture of the veil"
GEOMETRY
As said before the most preferred house plan is central courtyard one. The building is made of different elements which are representative of the vernacular architecture of that specific region such as:
1.     Thick walls
By increasing the thickness of the wall and increasing the mass, thermal inertia increase. throughout this strategy the heat absorbs through exterior facade in summer and interior spaces in winter can't be transfered easily.
2.     Central court yards
By the help of vegetation and pool inside the courtyard, evaporative cooling helps to decrease the temperature and by the height of the walls surronding the courtyard, shady area can be obtained and the open areas will turn to a fuctional space during the hot days of the summer.
3.     Wind towers
To rendering inside temperature more pleasant and using the cool streams of the air in higher level, this strategy applied to the houses. the height,  opening and openings of the wind towers changed according to the location and height from the sea level.
The air trap operates in response to the condition of the wind and sun radiation in the region. The inside and outside walls absorb a lot of temperature during daytime. As a result they cause a balance of temperature at night and bestow the attracted warmth to the cold night air. The thickness of the air trap walls and the dimension of the holes inside it are designed in a manner to allow enough heat to be transferred for better comfort. The light warm air inside the air trap ascends and is sucked away at the upper elevation. As a result cool air flows from windows and doors into the house and continues all night. (Kamyar Tolou Behbood)
4.     Large windows
In most cases, the windows and doors are installed in the northern and southern sides of the buildings, and thus, encourage a good air circulation. The south walls have more windows that promote the introduction of winter sun.\cite{sharif2015}
High ceiling and wide windows enhance the air circulation to provide comfort during summer.\cite{2015}
5.     Deep verandas
It provides a comfortable semi-outdoor open space for daily activities and night life specially in Summer times. It also helps to controll the daylight in summer, not to let the exterior weather become untolerable.
