“…More attention and scrutiny has been given to the process of landscape design and the application of natural vegetation as mitigation methods to control the increase of urban thermal discomfort. Due to its ability to improve urban temperature with minimal expenditures [10], natural vegetation can have passive effects onto urban designs (Yeang, 2006). By integrating the scientific knowledge about vegetation and water bodies with the creativity and inventiveness of design, the landscape design approach can balance the ecosystem and counter the effects of urban thermal discomfort.…”

“…The high surface area of natural vegetation in the tropical regions is able to supply shade and evaporative cooling. A number of climatic areas have resorted to using vegetated roofs as a means of improving thermal comfort, reducing air pollution, reducing storm water runoff volume, and increasing runoff water quality [10]- [13]. In the same way, vegetation is able to contribute thermal benefits, eliminate air pollutants, reduce the release of carbon dioxide, and ease [14].…”

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.

“…Many studies about Green Roofs System (GRS) have been made in recent years due to the multiple benefits that they offer, such as increase in urban forest area (Berndtsson et al, 2009), air purification (Yang et al, 2008;Li et al, 2010), reducing runoff Mentens et al, 2006;Berndtsson et al, 2009;Stovin et al, 2012;Speak et al, 2013), reduction of the urban heat island effect (e.g., Wong et al, 2003;Weng and Yang, 2004;Wong and Chen, 2005;Takebayashi and Moriyama, 2007;Lin et al, 2008;Santamouris, 2012;Wong and Lau, 2013), life extension of the roof (e.g., Saiz et al, 2006;Kosareo and Ries, 2007;Clark et al, 2008), reducing the acoustical noise (e.g., Renterghem and Botteldooren, 2009), preservation of biodiversity (e.g., Madre et al, 2013) and energy saving in the building (e.g., Onmura et al, 2001;Theodosiou, 2003;Castleton et al, 2010;Zinzi andAgnoli, 2012, Hong et al, 2012;Chan and Chow, 2013).…”

In this study, the results of a green roof model are presented and compared with experimental data. Good agreement between simulation and experiment were found for different experimental conditions that were carried out in a controlled environment laboratory. The study of green roof heat transfer processes is important because it allows a better thermal design in buildings; the use of urban forest area reduces the urban heat island effect and others improvements such as air purification. Also, with a mathematical model that accurately describes the heat transfer in the green roof it is possible to determine variables such as the local and averaged temperature inside the building and thus obtain the energy savings of a green roof over a conventional one. In this study a mathematical model of heat transfer in a green roof considers that porous materials form some of its layers and that the heat sources are introduced into the model through boundary conditions. In order to validate the mathematical model considering porous materials, the data obtained from the model and laboratory experimental data were compared. The results show that the inclusion of equations considering porous materials, inside the heat transfer model of the green roof, described properly heat transfer processes. Considering porous materials in the green roof model allows including effects due to canopy density, the amount of water contained in the soil layer or penetration of the radiation through the green layer.
