Events in the building industry in Nigeria in the last decade show the important role the private sector played in housing finance. With the advent of the public-private partnership concept in almost every sector of the socio-economic spheres of the nation, the role of the private sector in housing finance cannot be over-emphasized. This paper clearly states that the low-income public servants do not easily have access to housing finance. The responsibility of generating housing finance at a relatively low interest rate repayable over a maximum period of twenty five years rests on whoever seeks for a housing loan through the Federal Mortgage Bank or the Primary Mortgage Institutions. This paper seeks mediatory role of the private sector between this class of the society and the mortgage banks to source for funds to enable them to own their houses. The research method employed in this paper is the survey research in which questionnaires were administered on members of three housing estates, two housing estates in Lagos and one in Abuja. This paper exامینes the role of the private sector in the public-private partnership in housing delivery to low-income earners in Nigeria through housing finance. The findings showed that majority of the respondents had access to either mortgage or commercial banks to source for funding or the purchase of the houses.

Middle of squares, one of the components of physical aspect is considered as an appropriate indicator in designing successful urban squares, which consequently promotes visual quality. The present study aims to determine how the above mentioned aspect was presented in the Middle-Ages and Renaissance within Italian squares. Considering the aim of the investigation, library studies as well as visual documentations, with a historical-descriptive approach were applied in studying Italian community-oriented squares, Campo located in Siena, Del Campidoglio in Rome and San Marco in Venice. Results showed that, urban designers have employed some indicators, including physical aspect and its factors such as proportions, shape, surface design, materials, colors and topography in order to promote aesthetic-visual qualities, as well as human scale and unity of space to successfully design attractive middles in squares. These all, efficiently influence users’ presence, pause, movement type and trend, direction, speed and even their behavior. Accordingly, considering the mentioned aspect is of great importance in designing future squares.

One of the most important natural factors and critical facilities in Tehran is presence of Alborz Slopes River-Valleys which have been considered as natural tourist places for citizens since a long time ago, especially in hot summers and play effective role in creating a balance between manmade and natural spaces. Importance of these river-valleys as ecological pathways is enhanced with the increase in population and development of river-valley cities can become a vital element of urban life cycle. However unfortunately, their inappropriate use has only reduced the quality of life in their area. Design of riparian parks, establishing dynamic edges and creating lively urban space may give a new spirit into the lifeless body of these river-valleys. This paper has been written aiming at planning and design of sustainable resorts in the area of Kan River-Valley (The largest urban watercourse of Tehran) and attempted to answer this question that has Kan River ecological context and environmental characteristics to become a green urban corridor? Land use planning process has been used and strategic planning has been performed using analytical - descriptive method of artificial, natural and visual characteristics of the subject area, relying on the table Strengths, Weaknesses, Opportunities, and Threat (SWOT) and using present capabilities and removing barriers. The research results show that using sustainable ecologic landscape design and compatible with the environment, is an appropriate strategy for revitalizing the urban river-valleys.

Although in most of the rural development plans, relocation of informal settlements is often considered as an efficient solution to increase safety of rural communities against natural and man-made disasters, such as, earthquakes, fire hazards, floods, etc. an evaluation of recent experiences in the relocation projects show that the relocated community is often unsatisfied with the new residential areas. In most cases, the new residential areas are advantageous in compare to the informal settlements in terms of utility infrastructures and architecture design but the public remain reluctant to migrate to the new place. This paper, tries to evaluate the role of Community participation in the process of informal settlements relocation projects in Kerman province, an Iranian south-eastern state, by measuring people's evaluation of their own participation in the process of decision-making during five key relocation phases, namely, choice of new location, methods of relocation, architectural design of the new areas, construction procedures and supervision on the whole project. Questionnaire survey was employed to gather these data and was followed by statistical analysis (by SPSS software) in order to approve meaningful relationships. The results showed that lack of community participation had been responsible for a number of uninhabited settlement projects and some unfinished construction projects during the whole relocation process.

For over the past several decades, there has been a great concern about energy crisis and lack of non-renewable resources. Residential buildings take more than 25% of the total energy consumption and more than 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. On the other hand, traditional buildings of Iran were designed according to ecological conditions upon which, winter or summer sections were built. In this article, first, winter section of Yazd traditional homes, which are in hot-arid region and its thermal behavior, will be studied. This computer simulation is done and vaلیداted with energy-plus software, and temperature changes of these sections were measured with lascar electronics data logger. The results confirmed its reliability. Second, sections with different proportions such as three-door room, five-door room and seven-door room in different orientations, and their thermal behavior are analyzed and compared. So the thermal behavior of winter sections in Yazd traditional homes during a year shows that in winter, the proportions of five-door room in northwest orientation is better than others.
