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.

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.
