Investigating the influence of the climatic organ of Kolak on the natural ventilation of rural housing in Sistan and Baluchistan province (case Study: Qa`leh no village, Zabul county)
Abstract
Excessive energy consumption in the construction sector today has led to numerous environmental problems alongside massive waste of nonrenewable natural resources. In the midst of this, indigenous architecture has been able to adapt itself to the climate. One of the indigenous regions in our country is Sistan and Baluchestan Province, where one of the manifestations of indigenous housing is found in its rural dwellings, with a unique example being the utilization of passive solar systems in natural ventilation. Therefore, recognizing the climatic characteristics of our country's rural housing, which has been in response to the thermal comfort needs of residents, is one of the solutions to address new attitudes towards housing construction in new methods. In these types of buildings, natural ventilation consumes less energy and has less pollution compared to modern cooling methods. One of the climatic components of the rural housing in this region is the "kolah", which is a type of indigenous wind-catcher in the Zabol region. The purpose of this article is to investigate the impact of this type of wind catcher on providing thermal comfort in rural housing through natural ventilation. The study initially utilizes a qualitative research method in a descriptive-analytical approach and then examines the methods of utilizing wind for natural ventilation in rural housing patterns in the Qalehno village through field observation, focusing on the climatic element of wind catcher. The dependent variable of the research is thermal comfort, and the independent variable is wind speed. Subsequently, using Computational Fluid Dynamics (CFD) software, the relationship between the variables is analyzed, leading to an investigation of the impact of different conditions, including the current state (observed), assumption of wind blowing perpendicular to the wind catcher inlet, assumption of ventilation without utilizing this structure, and wind behavior in wind catcher with greater height in the optimization process. Studies have shown that this type of wind catcher performs best in the current state and through simulations, it was revealed that factors such as the placement of windows and intake vents should be emphasized.
