This study investigated the role of different indexes in open spaces of residential buildings in Tabriz, Iran. The main objective of the study was to evaluate the indexes with a higher level of effectiveness. Using a quantitative method, both descriptive and analytical data were entered into  SPSS, and structural equation modeling (SEM) was done using Smart PLS software. The case study included open spaces in Tabriz. The sample included 380 inhabitants of Tabriz residential buildings. The indexes were divided into two groups of central indexes and dispersion indexes. The important factor in central indexes was average; meanwhile, variance and standard deviation were the determinative factors in the peripheral indexes. Cultural anthropology of buildings’ open spaces showed that FA in emotional indexes and culture of open spaces grading had the highest level. Perceptional indexes were in the medium level, and physical indexes had the lowest level. Finally, the common classification of indexes included inspirations, memories, dreams, feelings, failure, thrill, ownership, sense of power, safety and security, and disappointment. A special attention should be paid to different dimensions such as cultural anthropology and issues related to human beings in public spaces, which cannot be solved with a single approach. Further studies are required to confirm the findings of this study in other cities and different cultural and societal levels and contexts.

Noise annoyance is a sensitive indicator of adverse noise effects and by itself means that noise affects people’s quality of life. In fact the acoustic environment has been neglected during the education of building engineers and architects relative to the thermal and lighting aspects addressed in education programs. This study aimed to investigate various non-acoustic factors on the annoyance caused by environmental noise in residential apartments. The surveys were conducted in Iran, city of Tabriz in October and November 2019. This research is descriptive-analytical and the type of research is correlational and causal. The statistical population of this study has formed the residents of different towers of Aseman-e Tabriz Residential Complex, which was selected as the sample size by using 373 Cochran's formula. The way of selecting sample people is randomly simple. The validity of the questionnaire has been confirmed by the professors and the reliability of the questionnaire has been obtained using Cronbach's special alpha formula for the variables in total equal to 0.857, and the variables of the situational section 0.902. Among all variables of the study, only four variables of fear with the 12.93% of variance changes, sensitivity to noise with the 11.85%, health issues of the residents with the 12.25%, satisfaction with the quality of construction and insulation with the 12.53% are the main factors influencing.

Social stratification engenders intricate disparities within social strata, denoted as "differentiation" in accordance with Pierre Bourdieu's conceptual framework. Consequently, urban buildings exhibit diverse facades, thereby exerting a profound influence on the city's aesthetic presentation. This study elucidates the pivotal role assumed by architects in aligning residential building facades with the discernment of citizens, drawing from Bourdieu's differentiation theory. Employing an applied and qualitative approach, the research method underscores the purposeful nature of the inquiry. The findings of this research categorize the perspectives of most Iranian architects on the notion of "citizen's taste in residential buildings" into four overarching themes: "building structure," "facade harmony with climate," "facade alignment with building function," and "visual aesthetic appeal of the facade".

High temperatures and air pollution are significant challenges in ensuring fresh air supply in the hot-humid climate of Asalouye City. These conditions compel residents to rely heavily on mechanical cooling, which subsequently escalates energy consumption and deteriorates indoor air quality. The primary air pollutants include Particulate Matter (PM), Volatile Organic Compounds (VOCs), and microorganisms. Fiber filters and electrostatic filters are the most common methods for purifying PMs from the air, with the electrostatic method offering advantages such as high efficiency, the ability to remove a wide range of particles, low-pressure drop, and no need for frequent replacement. This study proposed a ventilation system integrating a window,
a precipitator using electrostatic technology, a cooling coil, and an exhaust fan. The system's performance was evaluated using CFD simulation in Ansys-Fluent software (2021) to assess its effectiveness in reducing PM concentrations, pre-cooling incoming air, and maintaining the standard ventilation rate. The findings revealed that at air velocities of 6 m/s and 1 m/s, the system could completely remove copper, nickel, and sulfur particles with diameters of 0.1 µ and 10 µ. Additionally, the distance between the system's air inlet (window opening) and its air outlet (where air enters the interior) significantly influences the particle reduction level. The proposed cooling coil, however, only managed to reduce the air temperature by 2°C. In the absence of wind, an exhaust fan with a pressure jump of at least 250 Pa or 500 Pa is necessary to achieve the standard airflow and ventilation rate.
