Vernacular buildings in Qatar have employed some ingenious
passive techniques in order to restore thermal comfort within
the building particularly during the hottest hour of the day.
Such techniques are discussed hereafter
.1. Town layout
The buildings were joined close to each other.
The houses, on the other hand, shared walls and this minimized
the surface exposed to the sun. The streets were like a trench.
This helped the buildings to shade one another as well as to

The only spaces that received a great amount of sunshine were

At midday the courtyard received more solar radiation than
the shaded areas. As these heated up, hotter air rose and denser,

the prevailing wind which created a low pressure area in the open
space thus moving the air from the streets into the living spaces.
The walls of traditional buildings were massive with a thickness

Such materials include:
