The Range of Thermal Comfort in Traditional Residential Outdoor in Yazd

Today, a comprehensive discussion of development along with environmental and progressive issues increase can be considered. Quality thermal comprised of warm, cold, cool, radiation and comfortable which are significant qualities in experiences of space, not only on what people do in a space but also affects the feeling of space. So in this field thermal comfort issue is seriously raised. Today, the necessity for thermal comfort studies in the field of architecture and urban planning is important, but further studies in this area have been in the interiors, so the discussion of thermal comfort in residential outdoor (courtyard) was arisen. So in this research, Yazd houses due the specific climate have central courtyard houses which were studied. The main objective of this study is to determine the thermal comfort conditions in residential outdoor of Yazd and was based on the following questions: What are the factors of predicting thermal comfort in residential outdoor open spaces? What level of one's environment comfort, is influenced by thermal comfort in the open spaces? What are the most suitable criteria for evaluating the thermal comfort in open spaces? How much is the Range of thermal comfort in residential outdoor spaces in Yazd? Is there any difference between the characteristics of predicted thermal comfort and the feeling of thermal comfort? Their living conditions, thermal comfort range of temperature and humidity ranges in which the body's heat regulating mechanism is at its minimum as one of the requirements of the development of thermal comfort range should be illustrated for each area. In this article the range of thermal comfort in residential open space will be examined with regard to the location of most of the regions of Iran in hot and dry regions and the role of the yard in a selected set of split. The results of the evaluation findings based on personal relationships and environment variables that affect thermal comfort. The overall results show that on this basis, the amount of dry thermal comfort range of temperature based on comments and questions 24/23 and 25/42 centigrade degree among the participants in terms of relative humidity fitted 52/58 and 45/16. So factors that are affecting on the person's thermal comfort in outdoor, correlations and degree of importance vary globally and the little difference between the predicted thermal comfort and the feeling of thermal comfort was evaluated based on indicators. Psychological factors, including expectations of thermal adaptation, rather than the underlying natural spaces, the experience of the space, time spent in space, the right to choose, the condition before participating in outdoor residential in feature of a thermal sensation of space can to be effective. Respect all the principles of desert houce architecturesuch as exposure, proper form, plant-based, shadows, wind comfort in all seasons in outdoor are important. Confirmed that the traditional Iranian architecture and Urbanism in desert regions where temperatures soar to 45 degrees Celsius in the central courtyard with pond and plants, is the perfect situation. No doubt, these strategies will be energy-saving climate.
