International Journal on Advanced Science Engineering Information Technology The Effect of Landscape Architecture on Climate Change Nazanin Nafici, M. F. M. Zain Department of Architecture, Universiti Kebangsaan Malaysia 43600, Bangi, Selangor, Malaysia E-mail: n.nazanin68@gmail.com, fauzizain@gmail.com Abstract—Permanent environmental influences such as sun, fog, acid rain can destroy structures, buildings and the environment. Improving the quality of urban environment with utilizing green roof and green facades is illustrated for several years and installing them can offer multiple benefits. A detailed integrated presentation of green roof and green facade systems is provided in this paper. The aim of the research is to illustrate the effect of green façade and green roofs and generally greenery structure on the climate changes. The author tries to find a solution for the climate changes and environmental issues and resolving it by above- mentioned landscape architecture methods. Keywords— climate change; green roof; green façade; landscape I. INTRODUCTION Urban areas have a great role in the climate change. Attention to the climate changes represents our best chance to improve quality of life for the greatest number of people across the world. As a matter of fact, attention to the urban areas and its climate problems, like pollution can be a key factor solution of climate changes. Several features of modern cities interact with the changing climate to exacerbate the risks and increase vulnerability to climate change. Plants absorb sunlight to photosynthesize and grow, and their colouring reflects infrared. Because lush vegetation rarely exists as part of the urban landscape, save a few shrubs and some grass or potted plants, there is very little protecting a city from increased temperatures. Reflectivity aside, plants also contribute to moisture in the air which produces a cooling effect. Cities are where individuals may be the most vulnerable to the health implications of climate change. Important features for urban environment in landscape architecture that can be used in the productive way are building facades. Current-day green facades offer the potential to learn from traditional architecture but also to incorporate advance materials and other technology to promote sustainable building functions. Using green facades and green roof for building entrance, healing garden could take advantage of improvement to the human which can be provided by plants and this means improving of the quality of human experience in built environment. It is very important to choose plant species carefully that can it thrive under project site conditions. For example, under colder climates condition there are species of vines that even during the winter months they maintain their foliage. In design step of the projects in temperate climate zones, changing of seasons and how different plants will display their adaption to the environment should be considered. The aesthetic of green wall can be dramatically affected by these environmentally changes. II. GREEN ROOF A green roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. [1] There are two kinds of green roofs such as intensive and extensive. Extensive green roofs: growing medium is from 50 to 200 mm and vegetation limited to shallow rooting plants. Intensive Green Roofs: Deep growing medium that is about 200 mm or greater. It requires stronger roof structure, Wide range of planting possible, Fig.1 Green Roof [source: www.scholtensroofing.com] 70
