Urban heat island

Foreword There are a multitude of environmental issues created by traditional urban design systems. One major issue facing urban and suburban areas is the Urban Heat Island Syndrome. An urban heat island is the effect of built environment and human activity on ambient air temperature. Basically, concrete and asphalt structures with human activity can absorb high levels of heat from the sun. According to the EPA, buildings and pavements can heat up to 90oF hotter than the air; then in the evening, the surfaces radiate that heat back into the air heating it as much as 22oF. These increased temperatures have harmful effects on air quality, water quality, and sensitive individuals, such as, children and the elderly. Another important issue faced by the environment is the degradation of water quality resulting from runoff crossing urban areas. A myriad of…

Howard first proposed the urban heat island concept in 1833, he had examined the average temperature between London city and villages in 1920. As the result showed that the London city temperature is significant higher than the rural area in the day and night due to land usage increasing, lack of vegetation, artificial environments and heat production effect the high temperature in urban area than rural area. Therefore, UHI change the urban district of the micro-climate, impact of the present…

1. What is your understanding of the concept of climate change and the urban heat island effect? My understanding of the concept of climate change and the urban heat island effect is that they are both becoming more progressively harmful to our human health, the air we breathe, and water supply in our communities. Carbon dioxide (CO2) emitted from auto and factory emissions acts as a blanket, trapping long-wave infrared energy coming off the earth making our planet much warmer. Most radiation is…

Green space is part of a development in establishing grass, trees and vegetation in a community. Green spaces contain natural elements that could be placed and designed in an urban expansion. The establishment of parks and green landscapes restore an individual’s mental and physical health. In addition, the price of homes increase because of the eye-catching views that green space has to offer. The trees and vegetation efficiently create shades that will reduce the heat island effect, and can…

Urban trees provide a wide range of environmental, ecological, social, cultural and economic benefits. However, as natural objects, they are constantly under stress, and living in an unnatural habitat, which will primarily affect the tree crown. In this study, the Diameter at Breast Height (DBH), Crown Live Ratio (LCR), Crown Dieback (CDBK), Crown Transparency (CT), and Crown Chlorosis (CC) of trees at University of Toronto – St. George campus were assessed by field measurements and Google…

waterproofing membrane. Like modern roofs, green roofs provide insulation for aspects such as heat conservation and sound insulation. Green roofs can improve the air quality by using the vegetation and growing medium to help reduce the amount of air pollutants that go into the atmosphere. Green roofs also provide a habitat for wildlife which can lead to the increased biodiversity of plants and animals.…

Recycling As per the records, approximately 98% of all O’Hare Modernization Program construction has been reused by adopting recycling methods and were prevented from entering the landfills. Various elements of recycling are: a) All the Scrap Metals generated on site was hauled as needed for market rate credit. More than 4800 tons of metal was recycled. b) Almost 100 trees have been rescued from demolition sites and nine varieties were salvaged and reused. c) All construction vehicles used…

Urban sprawl is an inattentive issue that continues to harm the future of the world, unless the problem is addressed. The concept of urban sprawl is the “uncontrolled spread of urban development into neighboring regions” (“Urban Sprawl”). Across the globe, there has been urban sprawl in major cities, without consideration of future consequences. As society focal point is on celebrities and fashion, the focus on the destruction of the environment is not being acknowledged. The sprawl leaves…

As this is first microclimate research in Arwad Island, the above findings should be presented in a format that would be useful and appropriate for architects to make restoration and achieve the resilience for buildings and emphasizing the characteristics of the local environment during the hot period during control…

How the changing mass of solute effects the heat given out when dissolved in water Aim To investigate how the changing mass of a solute will affect the energy given out. Introduction Dissolving is when a solute is mixed into a solvent to form a solution. Dissolving can be either endothermic or exothermic. Endothermic reactions happen when the energy given out when bonds are broken, is greater than the energy given out when bonds are made. As more energy is used and taken in, the surroundings…
