The construction industry is known as one of the major consumers of natural resources and the creator of negative environmental impacts. Accordingly, the industry has increasingly taken steps to adopt sustainable and innovative strategies to minimize the negative impacts in this area. Many studies have been conducted on the concepts of lean, green, smart and sustainable in the field of construction, and a few of them have studied these concepts together. Therefore, the present study has presented a conceptual model with the aim of investigating how lean, green and smart concepts interact with the concept of sustainability in the construction industry. To this end, the systematic literature review has been adopted by the researchers of this study as a way to review and apply the existing research and studies to achieve a comprehensive understanding of the synergy between these concepts and how it affects the achievement of sustainability goals in the construction sector. The lean, green, smart and sustainable construction will each help reduce environmental pollution, reduce costs, reduce time, improve performance and increase quality of life for residents.The combination of these concepts provides a new perspective to reduce the negative effects of the construction industry, which paves the way for a transformation in the construction industry and architecture to achieve the three goals of sustainable development (environmental, economic and social) and encourage construction companies to implement and new technologies in construction projects. Finally, implementing these concepts separately or together will improve the construction process as one of the largest producers and consumers of waste and energy.

Children are an important group of residents in urban neighborhoods whose feelings and views about their neighborhood and its quantitative and qualitative characteristics have a great impact on their individual and social development. Therefore, paying attention to their demands in designing and organizing urban neighborhoods, especially in old and dilapidated neighborhoods that do not have good quality, is of considerable importance and necessity. So, the present cross-sectional study with a mixed method and focusing on the Hesarak Bala neighborhood located in the dilapidated area of Karaj, tries to examine and evaluate the views of fourth to sixth grade children regarding (1) their level of interest in their neighborhood (collecting data using interview and analyzing it with a statistical mechanism) as well as (2) their visual and written perspectives on their ideal neighborhood (based on their drawings and its analysis thorough an interpretive mechanism). In this regard, 134 children participated in the first part and 28 children in the second part. The findings in the first place indicate the lack of children’s interest in their current neighborhood and the significant relationship between this issue and their gender and age, and in the second place show the importance of various natural and artificial elements in their image and visualization of the ideal neighborhood. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . .

Many researchers have been conducted regarding to how select facade systems based on economic and environmental sustainability. For a sustainable system, both economic and environmental factors must be taken into account. Choosing facade materials solely based on environmental factors is not lead to the sustainable system. The research paper explores the environmental, acoustic, and economic impacts of facade materials, and finally presents appropriate facade materials for a building. The goal of this research is to investigate sustainability criteria for identifying the most sustainable facade material systems, among five options including Double Brickwork, Aluminum Composite Panel, Ceramic coating, Autoclaved Aerated Concrete (AAC), and concrete blocks. The two main factors are optimal energy calculated by combining two factors (thermal resistance, thermal conductivity coefficient) and sound reduction for Sanandaj city. Factors were tested in Design Builder's simulator environment, and finally, the results were analyzed through the AHP technique to measure the relative importance of different factors and rank the different facade materials. Based on the results, Autoclaved Aerated Concrete facades have the best energy mode in a simulator environment and sound reduction criteria based on the three factors mentioned.
