The architecture that has developed in arid zones of d middle east have had d consistent and deep routed building techniques which promotes passive climatic conditioning of their environments to provide shelter and comfort am their natural environment of hot arid desert
Contemporary design of homes in hot arid desert condition s have much to learn from the great history and development of city planning , building form and construction method of the past
Climatic condition
Hot dry weather in summer and cold in winter and dry
V. little rainfall
V. low humid in the air
V. low vegetation cover
High temp diff between day & night
Built environment
Ductility and implementation of urban and rural living condition with natural fact ors and use of this agents in v . adverse condition in this area , is considerable as dare to be expressed in one v. important achievement in the implementation of our traditional architecture & provide a suitable living environment in arid region s & is without water & grass
General urban & rural is as follows
Very dense
Urban area completely surrounded by narrow alleys sometimes irregular and covered with a vault
Buildings are joined together
The establishment of biological collection according to sun and wind
Building form
The traditional courtyard becomes the common mode for both urban & rural form
More common inter locking space arrangements could be found
Iran hot dry climate
Plateau plains, which are considered as the outstanding district of Iran, are located mainly in central and eastern parts of country. Being the biggest region and surrounded by high rough nesses the central plateau of Iran (Falat-e-Marakazi) has a dry climate. The two regions of Dasht-e-Kvir and Kavir-e-Lout occupying one seventh of Iranian area- are located in the center of Iran
which is totally barren with a very little rain.
CLIMATIC CONDITIONS
Hard and cold winters, warm and dry summers, very low rate of rain, air humidity, herbal cover, so much difference between day and night temperature and in salt desert and salt-desert border regions, the dusty winds are the outstanding climatic specifications in this region.
MORPHOLOGY AND URBAN TEXTURE
The villages and cities of hot-arid regions can be
compared to cactus bushes or desert plants. Because the life spaces of these regions consisted of urban spaces, pathways, yards and buildings are completely protected against undesirable winds and at the same time desirable winds and sun radiation are used with special arrangements.
Wall
Being considered as an important element in regional house of dry and hot climate , the huge wall has the approx thickness of about one mt. these helps to transfer the heat at night and remains the temp. low at day thus it provides com4ts the resident buildings
The domes , which where used as a covering roof for mosq , water reservoir and bazars are another type of roof in hot & dry regions . In addition 2 the structural reasons the dome shape roofing of building in this region has have some thermo physical reason as well
If flat roof used na usually square shaped bricks called paved one is used
Using the Local Material
The second principle is to using of local regional building materials for construction work where possibleit is preferable to use materials requiring low inputs of non-renewable energy in fabrication, transportation to the
site and in the construction process itself.
The forth principle is to the priority given to the
conservation and reuse of buildings, infrastructure and materials and also design buildings for flexibility so that a mix of uses can be accommodated under the same roof and so that floor plans are “robust”, in the sense that they can be adapted for different uses during the lifetime of the building.
