The study evaluated the physical qualities and satisfaction in students’ housing in selected Students’ Housing for the University of Ibadan. Through survey method, eight hostels were purposively selected to capture variation in gender, level of study and hostel design. The sampling frame showed that 5605 students at UI were found in 2,147 rooms. One out of every 10 (10%) of the rooms were selected which amounted to 215 students selected. The result shows that the functional qualities of the hostels were perceived among the students to be well above average (55.3%). Similarly, both aesthetics (95.8%) and structural (89.3%) qualities of the hostels were perceived to be excellent among the students. Also, respondents were satisfied with various services and amenities provided in the Halls of Residence (54.4%) and 35.3% expressed neutral satisfaction. The study concluded that, Physical qualities and Satisfaction are important in the study of Students’ Housing Design.

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.

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.

This study aims to build a model for the management and institutional organization to conservation and development of the Yesemek archaeological site in Gaziantep, Turkey. The scope of this research is the Yesemek archaeological site, which is known as the Yesemek Stone Quarry and Sculpture Workshop. Yesemek is the first outdoor sculpture workshop known in his tory. It is significant to preserve the Yesemek archaeological site, which has a unique value in Anatolian and Mesopotamian cultures with its original value and to pass on to the next generations. However, multidirectional planning and implementation processes are needed to protect and improve the area. The management of this complex process requires an institutional organization model based on the principles of efficiency participation, cooperation, transparency, and sustainability. As a result of the research, a model of cultural heritage management consisting of governance, spatial, socio-economic, cultural, and financial programs for sustainable protection and improvement in the case of Yesemek archaeological site is defined.

 International construction companies have settled in Africa and especially Nigeria, to compete for infrastructural projects, in a bid to extend their services across their borders. The trans-border extension of the services offered by these international multi-nationals exposes them to the political risk factors pertinent with the host country. In order to survive the harsh realities of the political risk indicators operational in Nigeria, especially the north-eastern part of the country, that has been plagued with civil unrest associated with the terrorist operations of Boko haram, it has become necessary to identify and manage these risk factors, to ensure the continuous survival of international construction companies in Nigeria. This paper seeks to identify and assess the prevalence of these political risk factors influencing the corporate performance of international companies operating in the North-east of Nigeria. Data for the s tudy was collected through structured questionnaires administered to 78 expatriates project managers from 6 international construction companies in the 6 states in the North East of Nigeria. Collected data was analyzed using relative importance index and factor analysis. Findings revealed that terrorism, corruption, insurrections, sabotages and kidnapping were the top five risk factors with the highest frequency of occurrence. It was also revealed that terrorism, kidnappings, sabotages, corruption and change in government are the risk factors with the highest impact on operations in the region. It is therefore recommended for the federal, state and local Governments to provide security for lives, properties and investments, companies should do more corporate social responsibilities and purchase political risk insurance cover to minimize their losses

There has long been a concern that evaluating building thermal performance on the basis of energy loads is inappropriate to achieve overall energy efficiency of houses, particularly passive houses, in temperate climates. Passive buildings designed to be free running may achieve better results in an appropriate evaluation system. The main objective of this study is to investigate differences between thermal performances of houses in different operation modes. The paper illustrates a relationship between indicators of building performance in free running and conditioned modes. Simulation is used to compare the predicted performances of conditioned and free running houses, respectively on the basis of annual energy requirements (MJ/m2) and Degree Discomfort Hours (DDH) in temperate climate of Babolsar, Iran. Despite a strong relationship between these two indicators, some significant differences become clear leading to a discussion of the persistent technical problems and issues, which are encountered when attempting to optimize an efficient architectural design. The result of this study persuades the architects to pay more attention to the process of building energy efficient design regarding to the building operation mod. Application of this result in the building labelling system can promote the passive building design which is an important step to achieve objectives of sustainable development.
