The concept of redevelopment is accompanied by actions and forecasts to improve the quality of the physical-spatial environment inthe cities, that is by the emergence of new facilities and conditions, improving the spatial environment is achieved. This requirement occurs when the coherence, coordination and the performance of the urban area is diminishing and is not responsive to the requirements of that area. The brownfields are amongst the inefficient urban areas and require redevelopment, which mostly include Deteriorated buildings accompanied by environmental contamination. The main issue of the present study is the lack of a compiled and appropriate roadmap to redeveloping the brownfields in Iran. Accordingly this article is seeking to introduce and present the defining indicators of brownfields, adapt these indicators to Iran's condition and achieve the redevelopment roadmap of these lands in Iran. In this regard, the codification of this article has been done by the descriptive-analytical method. Results of the study show that the main problem of Iran's planning system is the lack of a regulatory and legal description of brownfields on one hand, and absence of a compiled roadmap to lead urban development into the zone and use the capable potentials and opportunities for redevelopment

This paper examines the utility of the air pollution Model (TAPM) in simulating meteorology and dispersion of PM10 and wind data in order to assess The Impacts of Wind Variability Function on Urban Heat Island for the day of 25, November,

2012 in Karaj city that experienced severe degradation in air quality. Drawing, Skew-T diagrams, maps of surface pressure (500hp), omega (850hp) and atmospheric conditions at 300 – 900hp  level are used for analysis. Due to wind patterns, the air pollution behavior is simulated regarding to resolution of 5 km for output amplitude. Simulations of the PM10 and wind data in ten metric levels from three point of city are prepared according to synoptic conditions. Meteorology and PM10  dispersion results indicate that in spite of prevailed wind direction (West to East) in the mentioned day the effect of wind threshold on the air filtration is reduced and heat island formation is occurred as a result of reduction in air flow speed in urban areas. Therefore, it is essential to consider adopted strategies to mitigate urban heat islands such as the principles of bioclimatic architecture,  urban  morphology,  urban  infrastructure-related  measures  (architecture  and  land  use  planning) for  urban planning.

Evidence of the past shows variation in human settlements. Nomadic house the” Black Tent” shows relationship between humans and the natural environment surrounding them. Black Tents are made of natural materials consistant with environmental conditions. This paper discusses nomadic living space of some Iranian tribes located in different regions to show their unique architecture and culture. Rediscovering different architecture to understand this particular modus in nomadic life which need migration between their summer and winter residences. Given the factthat Black tent material is approximate similar, after thorough study in seven tribes in different provinces of Iran, it has been revealed tha  general ideas concerning the set up and installation of the tents have been the same. However, Black tent shapes and forms are different in those regions. In this regard, documenting how Iranian nomadic tribes arrange their settlement and the methods of using vernacular material by them, seems to be a good way to preserve their architecture. The Black tent is a synergy of nature and human's creative power. Method of data collection include desk studies as well as observation and documentation of indigenous habitat patterns of Iranian nomads by field observations and  ethnographyEvidence of the past shows variation in human settlements.

The industrialized building system (IBS) has been a common construction method for decades. Today, IBS is employed as a pioneer construction industry in developed and some developing countries. However, IBS has no proper position in the Iranian construction industry. Despite numerous advantages of building industrialization, most constructors adapt conventional techniques rather than building industrialization. This not only imposes human and environmental impacts but also wastes time and cost. The present work mainly aims to evaluate qualitative criteria influencing building industrialization in Iran based on Vitruvius’s three principles of architecture so that these criteria could be exploited to enhance building industrialization quality in Iran. Based on Vitruvius’s theory, architects should consider stability, utility, and beauty in their designs. Therefore, this theory was adopted as a suitable approach for the analysis and evaluation of industrialized buildings. Also, this study seeks to prioritize the building industrialization criteria based on the significant aspects of Vitruvius’ principles. This study reviews the literature and theoretical foundation in the first phase and then adopts a descriptive-survey methodology and field studies. To collect data, a questionnaire was developed based on the Likert scale. The validity and reliability of the questionnaire were verified. The statistical population consisted of academic professors and construction practitioners. The one-sample t-test, paired-sample t-test, and Kolmogorov–Smirnov (K-S) test were carried out in SPSS V.16.0. The findings revealed that the factor of structure in the principle of stability with the components of lateral load (i.e., wind and earthquake) resistance and shear load-resistant connections had the largest effect. Also, the economic factor of principle “utility” with the components of cost-effectiveness, construction time reduction, and mass construction had the second-largest effect in Iran.
