Abstract
The climatic conditions of each region of Iran are important parameters in the design and provision of thermal comfort in the design of housing. The purpose of this study is to provide appropriate models of climate design in Shiraz according to thermal comfort indicators. The research method in terms of descriptive-analytical nature and using modeling software (simulation) will be powerful Grasshopper software and is based on applied purpose. Climatic elements of Shiraz city in Ladybug plugin, download epw file of Shiraz city has been extracted from this method and in Ladybug plugin has been used for the simulation process. Then, using software to extract climate tables, diagrams of flowerbeds, and solar conveyors for optimal orientation for buildings, psychrometric diagrams were extracted to achieve the best design solutions compatible with the climate. The results of the research shows. The city of Shiraz in winter and spring, in the climate comfort zone and this situation is the same in February, March, and April, ie in terms of the temperature of these months (except 13 to 16 April) outside the climate comfort range Is located. ; In addition to placing most of the windows on the south side, the use of auxiliary heating equipment is also necessary. In June, July, August, and September, it is above the comfort level, so in addition to materials with high thermal mass, suitable canopies, as well as the use of a water cooler can bring the conditions inside the building closer to the comfort range.

Abstract
Expansion of urban areas has impacted on climate in local and global scale. As a result, residents’ life would be influenced accordingly. In this study, the effects of changes in land cover and land use change on climate of Shiraz and Fasa were studied in a long-term period. To ensure the normal data, Kolmogrov-Smirnoff test was employed. The minimum and maximum temperature parameters and relative humidity were evaluated using non-parametric Mann-Kendall and regression method in a 45-year period (1966-2010). The results showed a decreasing trend for the minimum temperature and humidity for Fasa and minimum and maximum relative humidity for Shiraz whereas other quantities showed an increasing trend. The study examined the effects of land use changes and land cover types in the 23-year period (1987-2010) using images of LANDSAT satellite of TM sensor on temperature pattern in two cities. During these 23 years, a reduction of 113 square kilometers for barren land of Shiraz and 5/7 square kilometers for barren land of Fasa and extending 110 kilometers residential users and 3/5 square kilometers in Shiraz and Fasa were reported.

Abstract
Urban segregation has been a problem of many cities of the world. Many researchers have interested in the urban segregation issues. Urban segregation has strongly concentrated poverty and created underclass. Different types of urban segregation exist, including income and racial or ethnical segregation, and depending on the contextual mechanisms within a city. To understand and plan a better community, urban planners needs to know how to measure the segregation and interpret the results. There have been many developments of segregation measures. Some evolved and some remained unchanged. This paper is studied the most used multigroup measures of residential segregation (8 indicators) in Shiraz city and between different socio-economic groups of it by using of the Segregation Analyzer Software. In general, the results show the occurrence of segregation in the medium amount to the high amount and by the calculated values of 0/7177, 0/5785, 0/5474 – 1, 0/5407, 0/3969, 0/3759, 0/3613, 0/3375 in the city of Shiraz. On the other hand, the use of Hot spots Analysis in the study area shows that the greatest concentrations of the socio-economic high group are in almost near the center of Shiraz city and the northwest of city, and for the socio-economic medium group exists in the west of city. Also there is the greatest concentration of the socio-economic low group in the southwest of Shiraz city.

Abstract
Land use maps are considered as the most important sources of information in natural resource management. The purpose of this research is to review, model, and predict landslide changes in the 30-year period by LCM model in Shiraz. In this research, TM Landsat 4, 5 and OLI Landsat 8 images were used for 1985, 2000 and 2015 respectively, as well as topographic maps and area coverage. Subsequent validation and detection of changes were made using the prediction model of variation The use of LCM markov and the model of user change approach. The images were classified into four classes of Bayer, garden, urban lands, and arable land for each of the three periods. According to the results, aquaculture is the most dynamic user in the area, which has led to an upward trend during 1985-2015, so that the amount (4337 ha, 12.7%) has been added to this area. The Bayer user change trend was also a downward trend during 1985 to 2015, reducing the 99.1995 hectares of this class. The results of the change in the 1985 changes with a kappa coefficient of 0.88, in the 2000 period with a CAAP of 0.77, and in the period 2015 with a Kappa coefficient of 0.92. The results of the change detection in 2030 are such that if the current trend continues in the region, 20.33% will be added to the crop category, so that in 2030, agricultural cropping will be 95.60% of the area of the area Gets In the Bayer and Garden uses 21.22% and 0.21% of the total area of each user has been reduced and has been added to the urban area. The prediction map derived from the Markov chain model is very important for providing a general view for better management of natural resources.

Abstract
The ‘Smart mobility’ has become an increasingly prevalent discussion topic in the past few years, not just in academic literature but also in cities’ policy and strategy. However,in many cities of the world and in our country, Iran has been associated with problems such as lack of citizen participation and inequality (caused by inefficient urban management). The present study has attempted with an innovative perspective to evaluate the existing infrastructure of mobility indicators (including transport infrastructure, public transport, sustainable transport, ICT) and the social dimensions of these infrastructures including the extent of citizen participation in use. Of these infrastructures) in eleven districts of Shiraz.The research method is descriptive-analytical and based on documentary and origin studies. Data gathering was field study by using a questionnaire. The 5-degree Likert spectrum technique was used to measure the value of indicators of the Smart Mobility. The results show that average smart mobility was higher in regions 1 and 6 than in other regions. the average smart mobility indicators are in 11 and 9 the lowest in other regions. The Urban Smart Mobility variable does not have an appropriate position in Shiraz, and this has not only affected its development process in recent decades, but also poses many challenges for its future development. Accordingly, urban planners should Consider the citizen participation and efficient urban management.

Abstract
Our country Iran is not far from the global changes of cities. One of these changes is the smart mobility that is Undeniable and inevitablein urban management today. Especially in metropolises, which are facing increasing population and various economic, social and environmental problems. In fact, metropolises always have many problems, most importantly transportation. Shiraz, as one of the major cities and one of the major cities of the country, has a special place. This position is of different cultural, historical, political and other aspects. Its population growth rate has also been steadily increasing due to its location. This trend of population growth over the past few decades has created problems and obstacles for sustainable and desirable management, most notably problems in the transportation sector. The same trend illustrates the need to emphasize smart systems in this city. Therefore, in this study, it is attempted to investigate and analyze Smart Urban Mobility and Social Sustainability for Shiraz. The research method is descriptive-analytical and based on documentary and origin studies. The results show that the mobility and displacement variables are in poor condition based on different dimensions of access, sustainable transport as well as ICT. Different indices of each of these dimensions point to the same issue, as its level of evaluation (significance level less than 0.05 and average lower than the criterion) points to their undesirability from the point of view citizens. The study of the impact of smart mobility indicators on Social Sustainability also shows that smart mobility indicators account for 23% of the total variance of Social Sustainability. On this basis, it should be noted that the mobility variable does not have an appropriate position in Shiraz, and this has not only affected its development process in recent decades, but also poses many challenges for its future development. The growing trend of the population and on the other hand the various social and cultural features as well as tourism are evolving in such a way that it requires a major focus on a systematic transportation based on smart city approach.

Abstract
Today, the number of elderly people is increasing due to various factors such as changing life expectancy and population distribution. On the other hand, this period of life requires special needs such as care and health to other external and environmental factors. The social phenomenon of the city is not separate from this population group, ie the elderly, and urban planners using environmental theories can take steps to improve the use of the elderly in the city and its public spaces. In this regard, the purpose of this study is to explain the components of the elderly-friendly city with an environmental psychology approach in the eight cities of Shiraz. After identifying the characteristics to obtain the required information using a questionnaire tool that Cochran's method was used to determine the sample and GIS data were generated using Moran analysis of the desired layers and then using hierarchical analysis and Hot spot analysis of overlapping criteria was performed using fuzzy functions and urban spaces needed by the elderly were identified. Then, by confirming the hypotheses in this field that attention to social components along with components of spatial structure can be appropriate to improve the urban environment, suggestions in this area from attention to access and public transportation to creating an environment Elderly entertainment was provided.

Abstract
rchitecture is always influenced by various indicators, the most important of which are climatic and physical-spatial indicators. These indicators are well observed in traditional homes and have played an important role in the use of clean energy. In this study, the aim is to study the climatic and spatial indicators of traditional architecture of Shiraz houses in order to provide a suitable model for housing design in order to use clean energy. The research method is descriptive-analytical and based on data collection through a questionnaire. The validity of the instrument was confirmed by elite and the reliability was confirmed by Cronbach's alpha above 0.70. The statistical population of the research consists of 27089 experts, specialists and people familiar with the architecture of the building and a member of the Engineering System Organization of Fars Province. The number of samples according to Morgan table is 384 people. The result of one-sample t-test showed that all studied climatic and spatial variables including green space, proportions and composition of architectural elements, materials, sustainable architectural design of spaces, building orientation, organizing spaces, water use, maximum use of wind , The use of light and providing coolness with shade at a level less than 0.05 were significant and in terms of the statistical population, were in a good condition. Among the spatial and climatic variables of architecture, the most impact was related to the orientation variable with a value of 4.03 and then green space with an average of 3.85. The regression result showed that the most effective variables in the design of modern houses are related to the variable of proportions and composition of architectural elements with a value of 0.151 units, ie 15%.

Abstract
Optimal condition of accessibility and rapid, easy, and safe travel to health_ treatment land uses can be performed by the systematic analysis of transportation sub-systems like behavior. Developed countries are in essential need of proper transportation system for better accessibility. This paper aims to develop model, considering mode chains as well as the individual characters. This study benefits the analytic and quantitative research methods in developing mode choice model to evaluate the movement pattern of travel to health care centers in Shiraz central district (district 1). Each mode is the dependent variable whereas the socioeconomic characters are the independent variables. Filled questionnaire and geographical information system is used in collecting data. To generate the model, multinomial logit model was used that shows public transport like metro and bus are not the popular modes in access to hospitals. Movement pattern cognition in accessibility to special urban land uses, has an efficient role in urban policies and planning, which can be generalized and indigenize to healthcare travel behavior in other geographical areas. Results show that car ownership will increased the private car travel rate 8 times according to beta coefficient.. Taxi is the mode which is used in all three travels. People with lowest range of income and education use bus as their mode. Besides metro travel also has significant relation with low level of income and increase the travel rate 9 times.
Keywords: logit Model, Hospital, vehicle, travel mode, Shiraz City.
