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.

In comprehensive urban development plan, a vision of Tehran has been considered as a world city. Tehran is also considered the regional medical center in the world of Islam in the comprehensive scientific map of Iran. In the era of globalization, medical tourism is a growing market in developing countries and has become one of fields of competition in regional development. According to the importance of strategic planning for the development of medical tourism in the globalization process, the effect of medical service globalization in the mega city of Tehran, and Tehran's response to the requirements are essential to investigate Tehran as a medical tourism destination. This is a descriptive survey and also an analytical and exploratory study. Quantitative and qualitative methods were employed in this research. Data were collected using in-depth interviews with 20 experts and a Delphi questionnaire. In the first step, a desk study was performed and the conceptual model was developed. External (environmental threats and opportunities) and internal (strengths and weaknesses) factors were analyzed by SWOT matrix. According to the SWOT matrix, medical tourism industry was in WO and SPACE matrix confirmed the result of the IE matrix. Percent using four strategies calculated and strategies ranked quantitatively by QSPM matrix as follows: i) Marketing and Information System Development, ii) Public Infrastructure Development, iii) Product Development, iv) Human Resource Development. Accordingly, policies were developed..

In this paper, an exchange of letters between the philosopher Jacques Derrida and architect Peter Eisenman is used as a catalyst to discuss the material qualities of glass and its relationship with the concept of transparency in architecture. In his criticism of an architecture devoid of human qualities, Derrida uses glass, defined through Walter Benjامین’s writings, as a hard and cold material that does not allow any human attachments and transparency as an absence of aura or a sense of awe. This paper attempts to elaborate that there can be different interpretations of transparency in architecture and that the material qualities of glass can be used to construct a different understanding of architecture in the current world of mass media and information. It is also argued that a particular approach to architecture has become possible in which textual constructs veil glassy buildings resulting in a translucent architecture that exploits different media to extend its influence beyond the limitations of a particular material, site or context.

Although a growing body of literature maintains that the construction industry plays a significant role in the economic development world-over, the extent of its regulation may, however, undermine the objectives of sustainable urban development. This study, as a result, investigates the factors influencing quality assurance within the building construction industry in Kenya, a case study of Kisii town. The target population comprised of 7430 residential developments from seven neighbourhoods that were spatially segregated using a high-resolution satellite image. Proportional stratified random sampling was thereafter adopted to select 364 developers through questionnaires. Results indicated that the key factors that undermine the extent of quality assurance within the building construction industry in the study area included failure to obtain a development permit, non-engagement of registered professionals in building design, an inadequate inspection of buildings during construction phases and unauthorized occupation of buildings by developers. The study concludes that despite the existing legal framework, these challenges continue owing to inadequate development control by the County Government of Kisii. This study contributes to the literature on the built environment by demonstrating how factors limiting quality assurance within the construction industry may be statistically analyzed.

In spite of the advancements made in science and technology, the world is still facing the perils of prevalence and epidemic of different diseases from one side and problems such as  inappropriate distribution of treatment giving services in a large number of countries. <br /> In such a condition there remains a need for the design of a comprehensive health system using the GIS based smart cards. This can facilitate having all common health, treatment services, such as issuing and receiving prescriptions, insurance services, having access to medical records which can accompany every individual. This will facilitate the development of social and spacial. Considering the fact that the data becomes regional and transferable (knowing they should stay confidential, and have permitted access) , predicated data banks in the health and hygiene net work management, such as offices and treatment giving insurance institutions could have all kinds of possibilities for planning, organizing, controlling and utmost management, in both individual and common health of the society. Although some developed countries are at the moment using smart cards in theirs health systems, but in this suggested system, the objective is to utilize the advantages of GIS smart cards being regional.  In this scheme a smart card is intended for each individual, and often loading the necessary information on it. This is used instead of his health service notebook and clinical record. In addition identification card used to access the patient’s medical record and prescription card is designed for doctors. Also the service offering identification card is designed for health centres and pharmacies. Predications should be made of the regional information in every visit to the physician or a clinic, upon which all the following possibilities can be obtained; all statistical reports based on GIS, research activities, supervising over the health and treatment distribution, number and reason for visiting the health care centers, defining the start of an epidemic and factors offering it, checking the nutritional diseases, analysing the concentration and spreading of different disease and their causes according to region or country.  All these data can help provide health maps, satellite pictures and defining various layers of information. Finally by the use of these cases optimum managing and development of a smart health and healing network can be made possible<strong>.</strong>
