The Effect of Improper Restorations on Thermal Load of Traditional Houses of Yazd (Case-studies: Oloomi and Tehrani houses)

Problem explaination: Traditional houses of Yazd are a valuable cultural heritage, which constitute the main part of the historic fabric of this city.
These buildings are as a manifestation of the history, civilization, urbanization, culture and identity of Yazd historic city, but - unfortunately - many of them have been evacuated and demolished over the time. Conservation, restoration and rehabilitation of this precious treasure, not only provide the opportunity to review and understand the values of these works but also it will transfer these values to future generations. ● Purpose of the paper: This paper is to study and identify common improper interventions in the city of Yazd’s traditional houses and examine the technical and functional damages caused by undesirable restorations specifically in relation to climatic conditions.
Methodology, case-studies and the research structure: The research method in this paper is "descriptive-analytical" and based on library resources and field observations. The research methodology is of experimental and simulation studies too. This paper reviews the case studies in the city of Yazd, which includes two examples of historic houses in the historic fabric of Yazd.
The concise It shows that incorrect restorations without the support of knowledge and scientific approach will have bad effects on climatic conditions in historic houses and will increase the thermal load and the costs of set the environmental conditions of the buildings at the time of utilization. The results clearly show that these kinds of interventions increase the thermal load of buildings and reduce the climatic desirability of them.
