From 60 decade sustainability issues and sustainable developing have opened a way in scientific meetings associated with environment and urbanization and architecture. Sustainability goals are improving of environment situation , less pollution and at least interference on land and interaction of natural and artificial environment , that most of these cases attracted attention in architecture and traditional urbanization of Iran . so , developing in architecture and traditional urbanization can be called sustainable developing . one of the basic features of architecture and traditional urbanization is adaptability to climatic factors . this feature led to by least interfering and pollution and energy , a city and building with less facilities can be provided comfort and welfare for its residents . the goal of this article is expressing basic that past architecture and urbanization focused on it associated with its climate for making of sustainable developing . in this article , considered to radiation as one of the climatic factors in different scales , like urban scale , urban space and architecture in yazd city and associated with traditional architecture and urbanization . in Iran , due to having hot and dry climate a different architecture ( specially in designing of local housing ) adaptable to climate formed that in such a space using of local or native construction materials having least undesirable impacts on environment and also , reducing of energy by using of local materials , led to environment sustainability and increasing of buildings durability . so in this topic, try to study local architecture of Iran in hot and dry climate based on environment sustainability and saving in energy and evaluate disadvantages of modern architecture in hot and dry climate in cases such as using material which aren’t adaptable to area condition , undesirable designing of building , no saving in energy and destroying of environment finally , we considered to collecting and presenting strategies in saving energy in building based on new technology .
