Abstract:
● 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 ofYazd 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 cityof Yazd’s traditional houses and examine the technical and functional damages caused by undesirablerestorations specifically in relation to climatic conditions.
● Methodology, case-studies and the research structure: The research method in this paper is “descriptiveanalytical”and based on library resources and field observations. The research methodology is ofexperimental and simulation studies too. This paper reviews the case studies in the city of Yazd, whichincludes two examples of historic houses in the historic fabric of Yazd.
● The concise results: It shows that incorrect restorations without the support of knowledge and scientificapproach will have bad effects on climatic conditions in historic houses and will increase the thermal loadand the costs of set the environmental conditions of the buildings at the time of utilization. The resultsclearly show that these kinds of interventions increase the thermal load of buildings and reduce the climaticdesirability of them.
Machine summary:
The Effect of Improper Restorations on Thermal Load of Traditional Houses of Yazd (Case-studies: Oloomi and Tehrani houses) Ali Saket Yazdi* Hamid Reza Beigzadeh shahraki** Sasan Kameli*** Abstract ● Problem explaination: Traditional houses of Yazd are a valuable cultural heritage, which constitute the main part of the historic fabric of this city.
● The concise results: 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 aim of this study is achieved by calculating the thermal load of the spaces in traditional houses before and after three common restoration actions.
This article has studied examples of these restoration actions in Tehrani and Oloomi house by applying energy simulation software.
But there have been articles written on the research done on the subject of thermal load, Badgirs (wind catchers), solar radiation and infiltration, simulated and calculated by Energy-Plus software.
"A Study of Solar Chimney Assisted Wind Tower System for Natural Ventilation in Buildings" is the title of an article which has applied Energy-Plus software to numerically model a solar chimney assisted by wind catcher system (Banzel & others, 1994).
Omitting wind tower in Oloomi house has increased the cooling load of the studied space by 61.
