Community is the main pillar of the urban body; and balance of social life in cities depends on preserving communities. During the twentieth century, the idea of residential-centered community has been offered in many modern theories and has been widely accepted for solving urban various problems such as management, social and human relations, health and welfare issues and aspects of meaning and identity. On the contrary, the concept of sustainable urban development has been considered a scientific issue in all societies in recent decades, when much of the literature on urban development has been allocated to the issue. The main argument of this paper is two issues of sustainability and urban communities, as well as how to link them in a topic. The paper will describe the necessity and importance of creating sustainable communities which have been originated from the consequences of climate change. Then, the concepts of sustainability and community are clarified; and finally the components of creating a sustainable community will be exامینed.

Migration of people to urban areas from the rural areas usually comes with its challenges in terms of infrastructural requirement and housing to cater for growing population. One of the challenge for the urban dwellers in Nigeria is that of adequate housing. The inability of the government to meet this demand has seen the people concerned seeking alternative solutions to housing need. The resulting settlements are usually unplanned hence becoming a challenge for government to manage in terms of providing infrastructure facilities. With the growing incidence of global warming and the attendant increase in flooding in most urban areas of Nigeria, especially between year 2000 and 2013, the safety of the people who live in slums have become a concern to the state governments due to issues of flooding and collapsed buildings. Government usually evicts such people and clear the settlement; however the people simply relocate to another area. The aim of this paper is to exامینe how community participation can be used to provide housing for the urban poor based on their living requirement, drawing from the experience of selected case studies from Kenya. The research method adopted for the study is a qualitative research method using case studies of selected communities in Kenya and selected communities in Nigeria. A comparative analysis is drawn with these communities. The research concludes by proposing how community participation process should be incorporated into provision of housing for the urban poor.

Designing buildings with the lowest possible cost base is an essentiality in sustainable architecture. Previously, due to the computational complexity of building's energy consumption, the environmental impact on thermal and lighting energy consumptions haven't been considered simultaneously. As non-linear relationships are often disclosed, a comprehensive approach is necessary to reduce the total energy need of a building and optimize the façade configuration at the same time. Solar radiation affects thermal and lighting energy consumption which depends on building fabric’s characteristics. In this paper a parametric method to optimize the window size and sunshade dimensions of an educational building in mild climate of Iran is presented. Through integrating thermal and lighting energy consumption, 6750 window and sunshade configurations are studied and compared. First, climatic parameters and thermal analysis are validated by on-site measurements. Then, the characteristics of the simulated model and all thermal and lighting parameters have been defined. Finally, the best solution is optimized through genetic algorithm. The results show that, in the first phases of the design process building’s characteristics should comply with national code regulations and then components of the building will be optimized. Additionally the horizontal windows with higher sill levels are more energy-efficient in classrooms.

Turbulence and inconsistency of urban physical system in the physical structure of Iran contemporary cities is one of the instances of identity crisis; the weakness of the educational system in the faculties of architecture and urban planning, the promotion of foreign culture in the domestic press, the weakness of the infrastructures of native culture education, the interference of experts from other scientific fields in architecture and urban planning, the weakness of urban management strategies, high expense housing and the necessity to supply housing for the needy people have created a turbulent city with eclectic culture and it made the native culture less prominent than before. The present research introduced the concept of “urban architecture”. The main presupposition of research is that the architecture of monuments in the historical texture has sufficient capabilities in the quality of physical structure of city and architects concurrently paid attention to the architectural characteristics of monuments and urban space quality. The purpose of present research is that to investigate the effective architectural factors to improve the social life of urban spaces thus the research question is that “how to architect while constructing architectural structures to shape an urban space with social quality?”  The necessity of the study is the role of urban spaces to shape the social life and the significance of the study is the possibility to clarify a “bottom-up” design procedure to consider the concept of “urban architecture”, and also to institutionalize qualifications for urban spaces through architectures. The present qualitative research has been conducted with the logical argumentation and causal- interpretative strategies and through documentary- field study in the case study of Abyaneh village. Research findings, while paying attention to the qualitative components of urban spaces resulting from monuments architecture, have proposed strategies to realize the concept of “urban architecture” consistent with the components of social sustainability.
