This book discusses the concepts and technologies associated with the mitigation of urban heat islands (UHIs) that are applicable in hot and humid regions. It presents several city case studies on how UHIs can be reduced in various areas to provide readers, researchers, and policymakers with insights into the concepts and technologies that should be considered when planning and constructing urban centres and buildings. The rapid development of urban areas in hot and humid regions has led to an increase in urban temperatures, a decrease in ventilation in buildings, and a transformation of the once green outdoor environment into areas full of solar-energy-absorbing concrete and asphalt. This situation has increased the discomfort of people living in these areas regardless of whether they occupy concrete structures. This is because indoor and outdoor air quality have both suffered from urbanisation. The development of urban areas has also increased energy consumption so that the occupants of buildings can enjoy indoor thermal comfort and air quality that they need via air conditioning systems. This book offers solutions to the recent increase in the number of heat islands in hot and humid regions.​

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.

Heat islands are urban and suburban areas that are significantly warmer than their surroundings. Traditional, highly absorptive construction materials and a lack of effective landscaping are their main causes. Heat island problems, in terms of increased energy consumption, reduced air quality and effects on human health and mortality, are becoming more pressing as cities continue to grow and sprawl. This comprehensive book brings together the latest information about heat islands and their mitigation. The book describes how heat islands are formed, what problems they cause, which technologies mitigate heat island effects and what policies and actions can be taken to cool communities. Internationally renowned expert Lisa Gartland offers a comprehensive source of information for turning heat islands into cool communities. The author includes sections on cool roofing and cool paving, explains their benefits in detail and provides practical guidelines for their selection and installation. The book also reviews how and why to incorporate trees and vegetation around buildings, in parking lots and on green roofs.

The Urban Heat Island (UHI) is an area of growing interest for many people studying the urban environment and local/global climate change. The UHI has been scientifically studied for 200 years and, although it is an apparently simple phenomenon, there is considerable confusion around the different types of UHI and their assessment. The Urban Heat Island—A Guidebook provides simple instructions for measuring and analysing the phenomenon, as well as greater context for defining the UHI and the impacts it can have. Readers will be empowered to work within a set of guidelines that enable direct comparison of UHI effects across diverse settings, while informing a wide range of climate mitigation and adaptation programs to modify human behaviour and the built form. This opens the door to true global assessments of local climate change in cities. Urban planning and design strategies 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

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.

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.

Bachelor Thesis from the year 2014 in the subject Geography / Earth Science - Demographics, Urban Management, Planning, grade: 12 on Danish grading system, Copenhagen School of Design and Technology, language: English, abstract: The aim of this report is to find out in which ways green infrastructure influences the urban heat island. Derived from this, there are other purposes for it. I want to find out what is the awareness level among people about this phenomenon and how involved they are in this matter. My Bachelor Project is a school with flat roof in Copenhagen. Because every new building in Copenhagen with a slope smaller than 30 must have a green roof, this report is also connected to my Bachelor Project. The first two chapters explain the urban heat island phenomenon and green infrastructure influence on it. Moreover, to reach a relevant conclusion I have decided to make two case study, one on Copenhagen, Denmark and one on New York City, U.S.A. Each case contains relevant information about the extent of urban heat island and how efficient green infrastructure is in mitigating it. Relevant information was from desk research and questionnaires among architects in Copenhagen, Denmark. The results of my report show that New York City is very affected by urban heat island, while Copenhagen has a potential for it but it is not yet considered a problem. I like to think that the most important point from my report is that any form of urban heat island should not be neglected and vegetation will always play a crucial role in a city healthy life."

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)
