Book Description :

Numerous studies over the past several decades focused on the effect of the Urban Heat Island. Initial efforts on understanding the factors affecting UHI contributed to proceed the appropriate solutions and mitigation strategies. Mitigation strategies comprise increase both urban albedo (reflectivity to solar radiation), and evapotranspiration. Albedo increases are obtained through high albedo roofing and paving technologies. An increase in evapotranspiration is achieved through a combination of decreasing the fraction of impervious surfaces and planting vegetation in urban areas. The outdoor thermal comfort is influenced by the perception and satisfaction of the pedestrians, especially in hot and arid climates. Consequently, this work focuses on the appropriate methods for reducing the Urban Heat Island and thus to enhance the pedestrians outdoor thermal comfort. However, there is limited research conducted on the outdoor thermal comfort in hot and arid climate. The studies on the mitigation the Urban Heat Island and the outdoor thermal comfort are almost non-existent for Baghdad city. Baghdad has a complex urban fabric with modern design constructions buildings, traditional and heritage houses. The climate in summer is hot, and summer months are considered the longest season with nearly 7 months of the year. This study focuses on investigating possible mitigation strategies to ensure how pedestrian comfort is affected by the constructions design choices comparing a traditional district to a modern one, and on how vegetation and shading patterns contribute to reducing the effect of UHI and improving the outdoor thermal comfort. Four different scenarios are designed to assess the role of vegetation elements such as trees, grass, and different shading patterns. The evaluation was performed on the hottest day in summer, the mean radiant temperature, specific humidity, air temperature, and wind speed distributions have been analyzed using ENVI-met software. Thermal comfort is assessed using the thermal indices the Physiological Equivalent Temperature PET and the Predicted Mean Vote PMV. Also, a proposal model is designed to evaluate the thermal comfort on the hottest day and the typical day in summer. The results revealed an improvement on thermal comfort in the typical day in summer. The study shows how the urban factors such as the aspect ratio, vegetation cover, shadings, and geometry of the canyon are crucial elements that urban planners and municipalities have to take into account, especially for new urban developments in hot, arid climate.

Book Description :

The Urban Heat Island provides simple instructions for measurement and an analysis of the urban heat island (UHI) phenomenon, along with greater context as to what a UHI means and what impacts it can have. With this further understanding, research on urban heat islands can impact a wide range of climate mitigation and adaptation programs, including city greening, changing surface albedo and permeable paving. The book empowers readers to work within a set of guidelines that will enable direct comparisons of urban development across multiple environments. This type of systematic classification opens the door to true global comparisons of climate change. In addition, the impact of urban planning and design strategies in different environments can then be evaluated for their effectiveness at mitigating these changes. Covers both on-surface and near-surface, or canopy, measurements and impacts of Urban Heat Islands (UHI) Provides a set of best practices and guidelines for UHI observation and analysis Includes both conceptual overviews and practical instructions for a wide range of uses

Book Description :

Conventional air conditioning is not a sustainable solution to the challenge of a hot or humid climate. The climate problem is compounded in so-called Urban Heat Islands, urban areas where the air can be 3–5°C hotter than its surrounding areas and where pollution levels are consequently raised. Including a colour section with thermal images and maps, this book explores the complex relationships between climate, buildings and plants, especially in urban heat islands. These relationships bear very critically on a range of environmental issues and point to some corresponding solutions. One chapter highlights some of the extensive research work carried out in Singapore, especially investigating the thermal benefits of greenery in buildings in the urban setting. Though several books have been written on urban heat islands, this work uniquely examines the linkages between climate, buildings and plants. It forms a reference for researchers and professionals such as architects, architectural science, landscape architects, building services engineers, urban planners and urban climatologists. It may also be useful for final year undergraduates or graduate students in these disciplines.

Book Description :

Urban Heat Island Modeling for Tropical Climates takes into account the different urban physics in tropical environments, presenting a way of UHI scaling for tropical cities. Topics include measuring, modeling and proper mitigation strategies, which account for the surface energy balance of tropics. Tropical cities are more susceptible to the effects of projected global warming because of conditions in tropical climates and the rapid growth of so many cities in this zone. The need for research on measuring, modeling and mitigation of UHI effects in tropical cities is of growing importance. This book walks through the basics of Urban Heat Islands, including causes, measurement and analysis then expands upon issues as well as the novel techniques that can be used to address issues specific to the region. Reviews topics related to understanding the fundamentals of modeling and impacts of urban heat islands Covers many techniques, from remote sensing, to numerical modeling and then applying them to urban climate studies in general, and in tropical cities Describes the scaling of urban heat islands based on long-term seasonal thermal parameters as feature-based classification systems using a probabilistic and fuzzy logic approach, unlike local climate zones (LCZs)

Book Description :

Urban heat islands are a new type of microclimatic phenomenon that causes a significant increase in the temperature of cities compared to surrounding areas. The phenomenon has been enforced by the current trend towards climate change. Although experts consider urban heat islands an urgent European Union public health concern, there are too few policies that address it. The EU carried out a project to learn more about this phenomenon through pilot initiatives. The pilots included feasibility studies and strategies for appropriately altering planning rules and governance to tackle the problem of urban heat islands. The pilots were carried out in eight metropolitan areas: Bologna/Modena, Budapest, Ljubljana, Lodz, Prague, Stuttgart, Venice/Padova, and Vienna. The feasibility studies carried out in these pilot areas focused on the specific morphology of EU urban areas, which are often characterised by the presence of historical old towns.

Book Description :

Le réchauffement global de la planète et les dérèglements météorologiques vont croître considérablement d'ici la fin du XXIe siècle. La ville n'échappe pas à l'influence de ces changements climatiques qui engendrent des îlots de chaleur urbains — caractérisés par des hausses de température parfois importantes dans le centre par rapport à la périphérie et qui entraînent dysfonctionnements et inconfort. Ce phénomène est dû à l'accumulation d'un certain nombre de facteurs : la densité urbaine, la circulation automobile, la minéralisation excessive et le déficit de végétal et d'eau dans les espaces publics. Les métropoles tentent d'agir. Dans cet ouvrage, chercheurs, experts et responsables locaux des villes de Barcelone, Lyon, Marseille, Montréal, Nantes, Rennes, Rome, Stuttgart, Toulouse et Vienne analysent l'impact que peuvent avoir les formes architecturales et urbaines, les dispositifs paysagers, ainsi que le choix de matériaux et de technologies de construction sur la réduction des effets néfastes de ces îlots de chaleur.

Book Description :

The Urban Climate aims to summarize analytical studies directed toward physical understanding of the rural-urban differences in the atmospheric boundary layer. Attempts to quantify conditions have met with some success. There is certainly a clear understanding of the physical relations that create the climatic differences of urbanized areas. Although some of the earlier classical studies are cited here, the emphasis is on the work done during the last decade and a half. This volume comprises 11 chapters, beginning with an introductory chapter discussing the literature surrounding the topic, its historical development, and the problem of local climate modification. The second chapter presents an assessment of the urban atmosphere on a synoptic and local scale, and examines the observational procedures involved. The following chapters then go on to discuss urban air composition; urban energy fluxes; the urban heat island; the urban wind field; models of urban temperature and wind fields; moisture, clouds, and hydrometeors; urban hydrology; special aspects of urban climate; and finally, urban planning. This book will be of interest to practitioners in the fields of meteorology, urban planning, and urban climatology.

Book Description :

The expansion without precedent of city boundaries determined the modification of the climatic conditions inside urban areas, with a direct impact on the environment and the population. Urban development implies fundamental changes in the natural setting, generating significant differences between the urban environment and the nearby areas in terms of meteorological parameters, air quality, and energy balance. Over the last decades, cities worldwide have experienced accelerated development, urbanization being one of the most important dimensions of global change. In Eastern Europe, another important matter is the forced industrialization from the communist era which lead to a complex process of urban change. This change influenced the urban climate of post-socialist cities. In such cities, the urban landscape was radically transformed with the emergence of over-sized production units and “dormitory neighborhoods” meant to accommodate their personnel. The replacement of natural surfaces with the built, impervious ones (with distinct caloric properties and lower cooling rates), is known as one of the main factors that generate the urban heat island effect. The topic of this book refers, therefore, to the urban heat island (UHI), as an example of climate change of anthropic origin, and to its atmospheric, biologic and economic impact (Yow 2007). The UHI phenomenon implies a temperature difference between the densely built urban areas and the nearby rural ones.

Book Description :

The power consumption due to air-conditioning of buildings becomes particularly significant in an urban environment because the temperature of the air of dense urban districts is higher than in the suburbs. This phenomenon, as well as the increase in the standards of living and other factors namely heatwaves, contribute to the growth of the traditionally low demand for artificial air-conditioning in Europe. Case studies make it possible to measure the heat island effect (the accumulation of heat in cities), to characterize the additional electricity consumption of the buildings in an urban environment, and to give an overall picture of the practices, techniques and materials which can help to cool the cities. Priority is given to the practices which avoid the need for artificial air-conditioning by taking into account the environment, the use of vegetation and " cool " materials for the construction of pavements and buildings. For the remaining needs for air-conditioning, the present systems of air-conditioning can also become more energy efficient. Case studies conducted in Seville made it possible to measure the dispersion of the needs for air-conditioning around their average value for the various zones of the city. One of the case studies evaluates the benefit associated with the systematic plantation of trees and other plants in Athens. Another case study relates to Paris and estimates the importance of centralized solutions for air-conditioning in an urban environment. This book results from a study launched by the European Commission and is written by authors from three European countries very concerned by heatwaves and their effects downtown : Greece (Athens), Spain (Seville) and France (Paris). All of them are professors or researchers in very high level laboratories (Group Building Environmental Studies in Athens University, Energy Laboratory in Ecole des Mines de Paris and in Seville University).
