The globe witnessed a rapid development of the concepts of sustainability, smart architecture, and intelligent buildings during recent decades. The Healthy environment, particularly thermal comfort, is an essential concern for planners, urbanists, and architects to produce a healthy and thermally comfortable environment. A better understanding of the parameters that affect the Outdoor Thermal Comfort (OTC) will enable urbanists and environmentalists to control the microclimate and to enhance environmental performance. Several parameters affect the thermal comfort of human-being such as air temperature, mean radiant temperature (MRT), air velocity, humidity, metabolic rate, and clothing insulation. Assessing the MRT is considered the most challenging parameter in outdoor spaces. Recent researches recognized several approaches to determine the OTC in different climatic zones. The influence of different climates and user groups has significantly altered the range of responses for thermal comfort. This paper focuses on reviewing the current state of knowledge on how to assess the OTC and the MRT in the hot arid climate. Results confirmed the integration of the appropriate OTC index with other design tools to evaluate the OTC and the MRT. It also confirmed that Physiological Equivalent Temperature (PET) and Predictive Mean Vote (PMV) are the most common indices. While ENVI-met and RayMan are the most common software to assess the OTC.

Due to fast urbanization, cities have grown with little or no urban planning and this has caused several problems to these environments, such as changes of urban microclimatic variables. This research aims to evaluate the changes in urban areas most affected from a microclimatic perspective, caused by changes in land use and occupation in recent years. Field research and data treatment were carried out, and it was observed the intensification of microclimatic changes in the city center, as well as in the West and Southwest areas of the urban tissue, due to significant changes in the urban structure, such as the urban intervention carried out on the Tarumãs Avenue along with intensification of traffic and urban density in these regions. The methodology used has also proved to be effective for monitoring climate changes over time in small and medium-sized cities with accelerated growth.

In the work, on the basis of the data of the analysis of theoretical works and the laboratory studies carried out, the prediction of the values of corrosion rates in the circulating systems of coke plants was carried out using the Langelier and Ryznar stability indixes. The laws governing changes in the thermal stability of water as a function of temperature and water quality indicators (pH, alkalinity, total salinity, calcium ion content) have been established. Analysis of the obtained data showed that there is a clear dependence of the scale-corrosion properties of water on temperature and its chemical composition. A stable and effective supplying water composition for the circulating water supply system of the Kharkiv Coke Plant has been established.

This paper assesses the operational data of a public transportation system, using the Bus Rapid Transit in Lagos State as a case study. Demographic data was collected through the administration of questionnaires to the commuters; this was carried out to observe variations in the population of the commuters from different perspectives. Some other categories of data were collected which include boarding and alighting, headway, arrival rate of commuters, waiting time of commuters and travel time data. These data were presented and analysed with MS Excel and Minitab statistical softwares. Results from the boarding and alighting data showed bus stops with high flux of commuters, these were at Ojota, Ketu, Mile 12, Costain, CMS and TBS. Probability distribution charts were prepared to analyze the remaining sets of data. This was carried out to study the distribution and consistency of the data. Coefficients of variation for the data were also estimated to study the variability of the data. From the study, the data followed normal distribution and they were consistent such that they can be used for further analysis of the system. It can be concluded that the distribution depicts the real situation at the study location. Thus, bus stops with high density of commuters should be provided with more buses so as to reduce the waiting time of commuters.

Urban open spaces (e.g. urban parks) play a pivotal role in improving the quality of life of city dwellers through accommodating various physical and social activities, while further creating social coherence for sustainable development. Due to the shortage of open green spaces in the city, caused by rapid urbanization in developing countries, some big, long-standing urban public spaces such as district parks have been retained, and improved to serve as the main public space for local people. However, such spaces commonly provide outdated, low quality facilities that discourage people from using the park. To satisfy users’ needs, local governments have launched campaigns to improve parks based on the ideas of domestic or foreign designers. The purpose of this research is to explore different behaviors of residents in an open space in Da Nang (Vietnam) which can support the future development and improvement of local open space in accordance with environmental behavior theory. User behaviors were identified and categorized based on their activities in the open space, collected using the place-centered behavior mapping method. Results of the statistical analysis revealed that this open space could be divided into three types, each of which had four dimensions: public facilities setting; openness; accessibility; and recreational facilities. The findings showed some aspects that need to be considered during the development process of open space as follows: 1) increasing the quantity and quality of public amenities; 2) separating accessible space and/or buffer space from already used space inside the park, particularly in the entrance zone; 3) providing space adjacent to the lake; and 4) removing obstacles (e.g. walls around the park) to give a clearer view from inside the park to the streets outside and vice versa. Also, the calculation model of evidence-based designs provides input data for re-planning or creating public space/parks to help designers, planners and authorities improve or design better open spaces in the future.

Cameroon through its Strategy for Growth and Employment (DSCE), has set up the construction of the Yaoundé-Nsimalen highway project. As part of the assessments of its potential effects on the environment, an ESIA was carried out, according to the framework law on the management of the environment. The acquisition of housing has resulted in an '' anarchic '' installation in the urban and peri-urban area. The construction of a highway as planned overlays on these facilities and poses a problem related to the liberation of spaces previously occupied. The purpose of this study is to identify, locate and classify the impacted goods by the highway construction project through Geographic Information Systems (GIS). Our methodology consisted first, making a satellite identification of the impacted goods, then a field campaign and finally a processing of the data collected. This study was also limited to the identification of two types of property, the buildings and parcels of land. Thus, it has been possible to distinguish and locate six categories of buildings, eight categories of parcels of land defined according to the Cameroon law No. 85/009 of 04 July 1985 on the expropriation for public purpose and the terms of compensation and according to Order No. 0082 / y. 15.1 / MNUH / D of November 20, 1987 laying down the bases for calculating the market value of buildings expropriated for reasons of public utility. The result of this study shows that mapping is a very practical tool for identifying and materializing the impacts that a project may have on components of environment. The GIS revealed a potential disappearance of 1502 building spread over 867 parcels of land.

According to the recent studies, there are wide range of psychological disorders in developed and developing countries with different levels of economic conditions. One of the most important psychological disorders and pressures is depression. An issue that has been neglected so far is impact of urban environmental quality on psychological health. Housing in this physical environment plays a very important role in psychological health indexes such as depression. The main purpose of this research is to investigate the relationship between qualitative indexes of housing and depression with a case study of at MoftAbad and Mardavij neighborhoods in Isfahan. Pearson correlation coefficient and linear regression have been used for data analysis. Independent variables of study include qualitative variables of housing that have been studied in accordance with literature in both internal and external dimensions. Dependent variable of study is depression. Depression Inventory Questionnaire of Beck et al. (1996) with 21 questions, used to measure depression. Results showed that variables such as interior design, indoor greenbelt, natural received light, natural ventilation, and plant diversity, walking possibility, quality of public spaces, and environmental cleanliness and security have most impact on level of depression of residents in urban neighborhoods.

Pollution free power production, quick installation and commissioning capability, less operation and maintenance cost and taking benefit of by means of free and renewable energies are all advantages of using wind turbines as an power generators. Along with these advantages, the main drawback of this source is the conditional nature of wind flow. Therefore, using reliable and efficient apparatus is necessary in order to get as much as energy from wind during the limited period of time that it flows strongly. Wind power is the fastest increasing renewable energy resource and wind power penetration in power systems increases at a significant rate. The high access of wind power into power systems in the present and near future will have several impacts on their planning and operation. A wind turbine transforms the kinetic energy in the wind to mechanical energy in a shaft and ultimately into electrical energy in a generator. Turbine blade is the mainly important part of any wind turbine. In this paper we consider single airfoil NACA 0018 and done CFD analysis at different blade angles 00,100,150 and 300 with constant wind velocity of 6 m/s. The analysis results show that blade angle 15º gives best possible power.

Elderly population growth has become a worldwide concern in recent years. For that matter, it is important to think about the current state of cities in a way to ensure a safe and independent transportation for the daily mobility of the elderly. Therefore, this study aimed to identify differences in the urban mobility of the elderly and non-elderly population based on travel characteristics. Data was obtained from a mobility research conducted within the metropolitan area of São Paulo, from which five variables were selected and treated for the study. The methodology was based on an analysis with a multinomial logit model. Results indicated that elderly and the non-elderly people tend to choose the individual transport mode first, followed by the public transport mode and lastly the walking mode. Moreover, non-elderly people tend to travel longer distances in their daily commutes, while the elderly people are more likely to do shorter trips in their daily commutes. In sum, the comprehension of mobility differences between elderly and non-elderly population allows a better understanding of challenges faced by the elderly in their daily mobility, as well as adequate planning for more inclusive cities.

Results indicated that elderly and the non-elderly people tend to choose the individual transport mode first, followed by the public transport mode and lastly the walking mode. Moreover, non-elderly people tend to travel longer distances in their daily commutes, while the elderly people are more likely to do shorter trips in their daily commutes. In sum, the comprehension of mobility differences between elderly and non-elderly population allows a better understanding of challenges faced by the elderly in their daily mobility, as well as adequate planning for more inclusive cities.
