Promotion of Urban Environment by Consideration of Human Thermal &amp; Wind Comfort: A Literature Review

Outdoor thermal environment is affected by variables like air temperature, wind velocity, humidity, temperature of the radiant surfaces, and solar radiation, which can be expressed by a single number-the thermal index. Since these variables are subject to annual and diurnal variations, prediction of thermal comfort is of special importance for people to plan their outdoor activities. The purpose of this research was to develop and apply the extreme learning machine for forecasting physiological equivalent temperature values. The results of the extreme learning machine model were compared with genetic programming and artificial neural network. The reliability of the computational models was accessed based on simulation results and using several statistical indicators. According to obtained results, it can be concluded that extreme learning machine can be utilized effectively in short term forecasting of physiological equivalent temperature.

“…Considering the crucial need to diminish the economic and environmental costs of energy consumption, much research on outdoor thermal comfort has attracted researchers for decades Djongyang et al (2010). Outdoor thermal comfort is a factor that improves human health Xu et al (2018) significantly in low-income communities, increases the attendance of people in urban spaces and public activities Ghasemi et al (2015), and helps to decrease the cost of energy consumption Kwon et al (2019). The main aim of this paper is to determine the relationship between three keywords: Urban Heat Islands, Urban Form, and Outdoor Thermal Comfort.…”

In recent decades, urban planners have endeavoured to mitigate climate change, by adaptation programs in order to alleviate its adverse effects on human health and wellbeing. Outdoor thermal comfort as an environmental factor affects human health, as proven by various research studies conducted in different climates. The aim of this paper is to explore the components of urban heat island, outdoor thermal comfort, and urban form. The relationship between these keywords and variables that affect outdoor thermal comfort was also analysed. The research method is descriptive-analytical and besides that, the qualitative research method has been used. The components of each keyword have been extracted based on professional theories. Finally, the ideal model of outdoor thermal comfort is proposed. This paper gives a comprehensive view to urban heat islands, urban form and outdoor thermal comfort

“…Despite many studies of the wind regime (including Johansson and Yahia; Ghasemi et al), the coefficient and degree of influence of the slope elevation and exposure on the aeration regime has not been revealed [20][21][22]. To obtain the most accurate information about the comfort and safety of aeration of residential buildings on the slopes, it is necessary to: generalize the available scientific and practical experience in the development of slope territories of the Russian Arctic; analyze the conditions of a person's ability to stay in a place with a harsh climate and difficult terrain; perform multivariate design and numerical experiments, as well as numerical modeling of air flows to obtain information about the future state of the air environment; and carry out a correlation analysis in order to reveal the relationship coefficient between the slope degree of the developed territory and the speed of the wind.…”

The land-use of slope terrain in the Arctic region is important and relevant, as vast territories that are reserved for proposed cities’ development have disturbed land relief. The relevance of the study is also associated with an increased interest in the development of settlements in the Arctic region, which has great territorial and resource potential. In addition to the complexity of the engineering support of such terrains, there are difficulties in organizing comfortable indoor wind comfort in the residential areas required for population well-being. The study focuses on specific conditions for residential areas design resilient to the harsh climatic conditions on difficult slope terrain to ensure the quality of life of the population in the Arctic region of Russia. The article focuses on the study of wind-chill parameters such as wind velocity and temperature for different slopes. The subject of this research is slope terrain aeration conditions of the Arctic zone in Russia. The research aim expresses the relationship between specific aeration of the slope area conditions and the layout design of residential areas to ensure comfortable living conditions for the population. The study was carried out using mathematical computational fluid dynamic (CFD) modeling of wind flows in the ANSYS Fluent program. The results of the study are graphs showing the distribution of comfort and discomfort zones in a residential area for different aeration conditions at different slope terrains. Implementation of the methodology for assessing aeration conditions for residential areas on slope terrains was carried out in the city of Murmansk. The scientific novelty of the study lies in the fact that there are no similar studies for the Arctic region in Russia. Research results can be used as a practical tool for justification of residential areas through a sample plan addressing their wind comfortability.
