“…Window shading should also be taken into account as it controls the amount of solar gain through the windows. In summary, many researchers have confirmed that substantial energy saving on space heating and cooling can be obtained through optimised window design [23,24] and proper use of thermal mass and insulation [25][26][27].…”

Abstract-Environmental awareness and energy efficiency are important concepts in terms of sustainability. Regarding the negative impact on the ozone layer, the largest portion is due to the refrigerants used with a share of 31% caused by mobile air conditioning (MAC) systems. In this study, refrigerants used in MAC systems were discussed in the terms of environmental aspects. First, the cooling capacity of the bus was calculated by using ASHRAE Handbook and EN 14750 -1 standard for the city of Istanbul in Turkey. Next, a conventional MAC system (with R134a) used for a bus was considered and the performance tests of this system were performed at SAFKAR Inc., located in the city of Izmir, Turkey while the calculations for R744 were made using experimental values of R134a at the same capacity. Finally, various aspects were presented.

“…Therefore, nature is a part of the complexity of cities, and each city has its own novel nature that humans have a role in creating and maintaining [29], [30]. An expanding and flourishing society demands decent psycho-physical regeneration which can be established through relaying aesthetic and cultural values by placing water bodies and greenery strategically throughout the city [31].…”

Abstract-This paper aims to investigate the effects of using natural resources that incorporates the basis of a sustainable city design in efforts to improve the urban thermal comfort in a hot and humid climate. Currently, one of the most crucial world environmental issues is urbanization in a hot and humid climate. In tropical areas, if the urban landscape is poorly designed, it will cause outdoor thermal discomfort. Natural plants and water bodies in the hot and humid landscape has a direct influence over the temperature of urban cities. Water bodies, for example, are able to lower the atmospheric temperature; whereas plants also can affect the surroundings passively. The effects of wet surfaces are increased if there is a presence of a shadow. Therefore, vegetation and water bodies are used in designing a sustainable city in order to increase the quality of outdoor thermal comfort in a hot and humid climate. This is hoped to provide a better and more comfortable human living environment.
