Ample Evidence

In the last decades, many studies have shown ample evidence that the existence of trees and vegetation around buildings can contribute to reduce the demand for energy by cooling and heating. The use of green areas in the urban environment as an effective strategy in reducing the cooling load of buildings has attracted much attention, though there is a lack of quantitative actions to apply the general idea to a specific building or location. Due to the large-scale construction of high buildings, large amounts of solar radiation are reflected and stored in the canyons of the streets. This causes higher air temperature and surface temperature in city areas compared to the rural environment and, consequently, deteriorates the urban heat island effect. The constant high temperatures lead to more air conditioning demand time, which results in a significant increase in building energy consumption. In general, the shade of the trees reduces the building energy demand for air conditioning, reducing solar radiation on the walls and roofs. The increase of urban green spaces has been extensively accepted as effective in mitigating the effects of heat island and reducing energy use in buildings. However, by influencing temperatures, especially extreme, it is likely that trees also affect human health, an important economic variable of interest. Since human behavior has a major influence on maintaining environmental quality, today's urban problems such as air and water pollution, floods, excessive noise, cause serious damage to the physical and mental health of the population. By minimizing these problems, vegetation (especially trees) is generally known to provide a range of ecosystem services such as rainwater reduction, air pollution mitigation, noise reduction, etc. This study focuses on the functions of temperature regulation, improvement of external thermal comfort and cooling energy reduction, so it aims to evaluate the influence of trees on the energy consumption of a house in the mid-western Brazil, located at latitude 15 ° S, in the center of South America. The methodology adopted was computer simulation, analyzing two scenarios that deal with issues such as the influence of vegetation and tree shade on the energy consumption of a building. In this way, the methodological procedures were divided into three stages: climatic contextualization of the study region; definition of a basic dwelling, of the thermophysical properties; computational simulation for quantification of energy consumption for the four facade orientations. The results show that the façades orientated to north, east and south, without the insertion of arboreal shading, obtained higher values of annual energy consumption. With the adoption of shading, the facades obtained a consumption reduction of around 7,4%. It is concluded that shading vegetation can bring significant climatic contribution to the interior of built environments and, consequently, reduction in energy consumption, promoting improvements in the thermal comfort conditions of users.

Abstract: Nowadays, the majority of Indonesian people live in the dense urban kampungs. Some of those kampungs laid on the riverside, as a marginal area -- due to their low economic value of the land. They have specific conditions especially on the limitation of infrastructures and facilities for children activities in the settlement area. This research is a part of my dissertation paper, which aims to gain how children (mainly school-age children) coping with such condition. This study is a qualitative exploratory research, meanwhile, observation and interview were used as collecting data methods. Kampung Ngampilan in Yogyakarta, Indonesia, was chosen as a case area, because of its unique characteristics: located on the riverside of Winongo River, had a high density, and most people have low economics. As the result, this study found that natural setting, especially river area and its surrounding vegetation, is a focus location for children to release live stress in their settlement, due to two space aspects: thermal comfort and visual comfort. This condition was triggered by the limited area of their house so that the children prefer to go out from their house especially after attending school in the afternoon. This results will be useful as a reference for urban kampung planning, especially in riverfront area.Keywords: children, kampung, environmental press, natural settingAbstrak: Mayoritas penduduk kota Indonesia tinggal di kampung berkepadatan tinggi. Sebagian dari kampung -kampung berada di bantaran sungai sebagai salah satu area kota yang dianggap marginal karena nilai ekonomi lahan rendah. Kampung-kampung umumnya berkondisi khas dan memiliki keterbatasan infrastruktur termasuk fasilitas untuk kegiatan anak-anak di permukiman. Studi ini merupakan bagian dari disertasi penulis, yang bertujuan mengetahui bagaimana anak-anak (terutama anak usia sekolah dasar) menghadapi tekanan lingkungan. Kampung Ngampilan dipilih karena merupakan kampung kota yang sangat padat, terletak di tepi sungai, berkontur curam, dan warganya termasuk kelompok ekonomi menengah ke bawah. Kajian ini menggunakan metode kualitatif eksploratif, dan penggalian data dilakukan dengan metode observasi lapangan dan wawancara. Penelitian menemukan, seting alami kampung, khususnya sungai dan vegetasi di sekitarnya, merupakan area pilihan utama anak bermain, karena memiliki dua aspek kenyamanan, yaitu kenyamanan termal dan kenyamanan visual. Pilihan anak-anak dipicu oleh kondisi rumah mereka yang sempit, sehingga mereka lebih memilih keluar rumah sepulang sekolah atau sore hari. Temuan ini dapat menjadi acuan bagi pengembangan kampung kota Indonesia yang lebih kondusif untuk anak, khususnya kampung tepi sungai.Kata kunci: seting alami, tekanan lingkungan, kampung kota, anak

<p>Designing urban facades is considered as a major factor influencing issues<br />such as natural ventilation of buildings and urban areas, radiations in the<br />urban canyon for designing low-energy buildings, cooling demand for<br />buildings in urban area, and thermal comfort in urban streets. However, so<br />far, most studies on urban topics have been focused on flat facades<br />without details of urban layouts. Hence, the effect of urban facades with<br />details such as the balcony and corbelling on thermal comfort conditions<br />and air flow behavior are discussed in this literature review. <strong>Aim</strong>: This<br />study was carried out to investigate the effective factors of urban facades,<br />including the effects of building configuration, geometry and urban<br />canyon’s orientation. <strong>Methodology and Results</strong>: According to the results,<br />the air flow behavior is affected by a wide range of factors such as wind<br />conditions, urban geometry and wind direction. Urban façade geometry<br />can change outdoor air flow pattern, thermal comfort and solar access.<br /><strong>Conclusion, significance and impact study</strong>: In particular, the geometry of<br />the facade, such as indentation and protrusion, has a significant effect on<br />the air flow and thermal behavior in urban facades and can enhance<br />outdoor comfort conditions. Also, Alternation in façade geometry can<br />affect pedestrians' comfort and buildings energy demands.</p>
