Abstract

Among the teachings of Professor Pirnia about the traditional architecture of Iran, there are clear references to "Iranian golden rectangle" and "arched covering" and its use by traditional architects.

Many elders have stated that Iranian architects have used these proportions to create architectural spaces in buildings. This research aims to analyze the effect of geometry on the body and architectural form of the bathrooms of Kurdistan province. Questions of the present research: 1. What has been the influence of geometry on the formation of the "Iranian golden rectangle" in the bathrooms of Kurdistan province? 2. What kind of " Arch covers " were the different spaces of the studied bathrooms? Information has been collected by means of library studies, field survey and drawing. By selecting 14 samples from the bathrooms of Kurdistan province, by analyzing the architectural plans and main building components such as: bineh and hothouse, the hypothesis of the application of this hidden geometric framework in the plan of most of the bathrooms is confirmed. The plan of some of the studied bathrooms follows the Iranian golden rectangle, or its other proportions. According to the coefficient of variation, the conclusion of the authors is that looking at the actual conditions and the plan pattern of the bathrooms in Kurdistan province, the small amount of error in the number of the bathrooms is due to the separation and division of the land, and the designers with Therefore, they tried to bring the ratio of the important spaces of the bathroom closer to the relative value of the "Iranian Golden Rectangle". The covering of the main spaces, including the bineh and the hothouse, was often used toize, and the covering between the toize was of Colombo and Karbandi type . Irrespective of any climatic conditions, the coating of hot-houses is less elastic than the coating of bineh, due to the preservation of heat in the environment of the hothouse.
