Abstract

This research examines the internal thermal comfort of historical houses in Isfahan from the Qajar period, focusing on the impact of wall materials. In Iran's hot and dry climate, houses must be designed to protect against direct sunlight and intense heat. The Dehdashti and Sartipi houses serve as successful examples of sustainable architecture that provide thermal comfort through the use of earthen walls and designs compatible with the hot and dry climate. Earthen materials play a crucial role due to their high thermal capacity, insulation properties, and breathability. Both houses have harmonized with local climatic conditions through the application of indigenous architectural principles and local materials. The research employs a quantitative and descriptive-analytical methodology, utilizing software such as AutoCAD, Rhino, and Design Builder for data analysis. Ultimately, the findings indicate that most historical buildings in these areas are constructed from high thermal capacity earthen materials, with an assessment of occupant dissatisfaction hours also conducted for these two houses.

Studying the effect of wall materials on thermal comfort of traditional residential buildings in hot and dry climates (Case studied: Dehdashti and Sartipi House)

Highlights

This research examines the internal thermal comfort of historical houses in Isfahan from the Qajar period, focusing on the impact of wall materials.
Houses must be designed to protect against direct sunlight and intense heat, which has been successfully achieved in the Dehdashti and Sartipi houses.
Earthen materials play a crucial role in providing thermal comfort due to their high thermal capacity and insulation properties, and buildings should utilize these materials.
The findings indicate that dissatisfaction hours for occupants have been assessed in these two houses, highlighting how the historical structure of these buildings has adapted to climatic conditions.
