Energy efficiency in office buildings has been the center of attention for many researches. This special attention is due to highly energy consumption in this building type. Refinement of facade and building’s envelop is a good approach to reduce buildings energy requirements. Double skin facade concepts are commonly used to achieve that object. Although the concept is not new, there is a growing tendency from the architects to put it into practice. However inappropriate selection of technical parameters in this kind of façade, such as its interior/ exterior openings, layers, materials and sهادیng device would lead to reverse expected results. The objective of this study is to improve and optimize the thermal performance of an office building in hot and dry climate. For this purpose a suitable double skin façade concept is designed to reduce the building’s annual energy requirements. This concept is optimized by integrating with a windcatcher. The optimization is performed based on simulating a designed office building by Energy Plus software. The results revealed that double skin façade integrated with wind catcher can significantly reduce annual energy requirement by 26.65%. The proposed solution can be considered as an effective platform for sustainable architecture and reduction of energy consumption.

City growth and environmental difficulties last decades leads the art of urban design and development think more precisely and new approaches for conserving environment and developing urban areas have been evolved.The present study deals with concepts related to ecology in the city and in particular the theory of Ecological Urbanism and its criteria is expressed. Also theory and characteristics of cultural landscape is described. Persian traditional architecture and urban design especially in historic urban fabric has unique criteria, Shushtar ancient urban fabric is investigated in this research and its extraordinary characteristics are compared with theories mentioned above.This paper is based on quantitative and qualitative research methods reviewed recent and reliable articles and documents. Also case study is assessed by reviewing, historical books and different official documents in addition a complete assessment of case study is performed by site survey, socioeconomic survey, physical survey, and demographic analysis. Plenty of data gathered by questionnaires, interviewing officials, authorities and residents. Result came out from comparison theories and case study indicates that Shushtar has both ecological urbanism and cultural landscape values and it could be argue that cultural landscape are special features of the culture, art and relation between human and nature in each society, they were existed long before the eco urbanism criteria formed, yet, it seemed there are some similar criteria to define them that illustrate the inseparable fact and relation between them.

The existence of brownfields in cities, and their common disadvantages, such as pollution and their detriment to natural habitats, have damaged local communities and their environment over time. Whereas the renovation and regeneration of these brownfields and transforming them into centers of activity could assist the economy and society to flourish. At the same time improving the quality of the environment could allow us to attain healthier, more attractive and safer communities. A neighborhood is a social network with a social and regional identity and a place where social interactions occurs. Focusing on enriching the neighborhood, nourishing social life and meeting the social and intellectual needs of the individual. The renovation of the defunct strip of land where the Tehran-Tabriz railway existed and its transformation into a linear park does not only have a positive effect on the local economy and environment but also connects the northern and southern sections of Yaftabad, by increasing safety and social interactions and enriches the local community. This research aimed to answer the following questions: 1- What are the guidelines of improving urban development and the quality of life of the people in regarding restoration and renovation of useless lands? 2- Is the construction of a ‘Green’ Pathways on the borders of brownfields could integrate neighborhoods? In order to address these questions, a descriptive-analytical method was used. In addition to library research and analysis of previously tested procedures in this field, by the help of a questionnaires, which was distributed through local population to specify their requested standards and quality requirements. The results showed that the people greatly desired this brownfield regeneration to a new improved environment and community. In the planning segment, with attention to standards set by the people, suggestions were presented.

 Nowadays, tourism is affected by the knowledge of a region’s climatic characteristics. Therefore, it is crucial to identify the potential regions and appropriate time for attracting tourists in relation to climatic comfort. Due to having climatic diversity and water resources such as rivers, waterfalls, caves and hot springs, Khorassan رضوی province is one of the potential regions for tourism attraction in IRAN. This study attempts to assess human comfort or discomfort for recreational and water sports activities according to Equivalent Effective Temperature (EET) index using meteorological data from Khorassan رضوی synoptic station for 1990-2011. Furthermore, the climatic comfort zoning map for tourism in the province was made by ArcGIS and Geographic Information System (GIS) potentials by inverse distance weighting (IDW) interpolation method. The results showed that October, June, September, April, May, August and July have the best comfort conditions for recreational activities and water sports, respectively. Also, Nishabur and Chenaran cities with 4 and Mashhad with 1 month had the longest and the shortest monthly periods for using water resorts, respectively. Similarly, in this research, available appropriate tourism areas are introduced according to the EET index for different months in order to achieve a higher understanding of the province’s potentials.

The cons truction indus try is one of the mos t energy-consuming and Contamination indus tries. Lean cons truction (L.C.) is an advanced manufacturing approach that could potentially bring novel developments in the cons truction indus try and seeks to elevate the value of the building, diminishing was te. Off-site cons truction (OSC) techniques have numerous advantages. Recent research s tudies have outlined the advantages of bringing together L.C. and OSC. This research aims to identify the elements of blending L.C. and OSC for the Indus trialization architecture framework. The core ideas that are integrated into the framework are addressed and discussed. This research employed a 3-s tep bibliometric review of indus trialization research within the cons truction and manufacturing sectors. A comprehensive sys tematic literature review technique to review the literature on L.C. and OSC for indus trialization architecture identified factors of integrated L.C. and OSC for indus trialization architecture and arrived at a conceptual model by recognizing these components. To refine AEC performance toward indus trialization cons truction, The increased efficiency of the enhanced production sys tem is taking a more prominent place. The introduction of automation and robotic sys tems into the cons truction process, pre-fabrication technique, cons truction 4.0 and use of information communication technology and digital technology (BIM, RFID,...), use of DFMA technique (design for manufacture and assembly) and sus tainability ability for the elimination of cons truction was te are factors for integrating L.C. and OSC for indus trialization architecture. This document provides a reference for future cons truction direction to achieve indus trialization cons truction.
