A study of climatic comfort conditions in the spatial-physical patterns of tradi-tional neighborhoods’ fabric: The case of Hamadan’s old neighborhoods

Backgrounds and research goals: The unbridled expansion of cities in recent dec-ades has led to the inefficiency of large parts of the structure and spatial organiza-tion of cities and the decline in climate comfort in them. Numerous policies have been proposed in the face of the problem of declining environmental quality and especially their climatic comfort, and various programs have been implemented in this regard. Therefore, this study tries to review the theoretical foundations in this area, finally appropriate solutions for the development of neighborhoods and neigh-borhood spaces in the climate of Hamadan has been proposed.Research method: The method of this research is that at first the effective compo-nents on climatic comfort and urban form were obtained by studying and examining the views of experts. To analyze the data, the simulation method and Ecotect Auto-desk software were studied in three traditional neighborhoods of Hamadan and ac-cording to the results, the factors.Findings: The results of the research show that Kababian neighborhood in the cold seasons of the year has more conditions to enjoy the sun in the morning and even-ing, but in the two neighborhoods of Haji and Aghajani Bey in the cold seasons should make more arrangements to enjoy The amount of sunlight used. Due to the fact that the amount of shading in these two neighborhoods in this season is more than the Kababian neighborhood and special measures are needed to create climatic conditions.Discussion and conclusion: In general, and according to the findings, one of the im-portant factors in optimizing traditional neighborhoods can be the use of centrifugal patterns in creating neighborhoods can increase the level of climate comfort in neighborhoods.
