This title provides architects and urban design professionals with an understanding of how the structure of built spaces at all scales affects microclimatic conditions in the space between buildings and analyses the interaction between microclimate and each element of the urban landscape.
Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
This book provides the reader with an understanding of the impact that different morphologies, construction materials and green coverage solutions have on the urban microclimate, thus affecting the comfort conditions of urban inhabitants and the energy needs of buildings in urban areas. The book covers the latest approaches to energy and outdoor comfort measurement and modelling on an urban scale, and describes possible measures and strategies to mitigate the effects of the mutual interaction between urban settlements and local microclimate. Despite its relevance, only limited literature is currently devoted to appraising—from an engineering perspective—the intertwining relationships between urban geometry and fabrics, energy fluxes between buildings and their surroundings, outdoor microclimate conditions and building energy demands in urban areas. This book fills this gap by first discussing the physical processes that govern heat and mass transfer at an urban scale, while emphasizing the role played by different spatial arrangements, manmade materials and green infrastructures on the outdoor microclimate. The first chapters also address the implications of these factors on the outdoor comfort conditions experienced by pedestrians, and on the buildings’ energy demand for space heating and cooling. Then, based upon cutting-edge experimental activities and simulation work, this book demonstrates current and forthcoming adaptation and mitigation strategies to improve the urban microclimate and its impact on the built environment, such as cool materials, thermochromic and retroreflective finishing materials, and green infrastructures applied either at a building scale or at the urban scale. The effect of these solutions is demonstrated for different cities worldwide under a range of climate conditions. Finally, the book opens a wider perspective by introducing the basic elements that allow fuel poverty, raw materials consumption, and the principles of circular economy in the definition of a resilient urban settlement.

Global Urban Heat Island Mitigation provides a comprehensive picture of global UHI micro-thermal interaction in different built environments. The book explains physical principles and how to moderate undesirable consequences of swift and haphazard urban development to create more sustainable and resilient cities. Sections provide extensive discussion on numerous UHI mitigation technologies and their effectiveness in cities around the globe. In addition, the book proposes novel UHI mitigation technologies and strategies while also assessing the effectiveness and suitability of UHI mitigation interventions in various climates and urban forms. - Adopts a multidisciplinary approach, bridging theoretical and applied urban climatology with urban heat mitigation - Compiles disparate urban climate research concepts and technologies into a coherent framework - Includes contributions from leaders in fields from around the globe
The combination of global warming and urban sprawl is the origin of the most hazardous climate change effect detected at urban level: Urban Heat Island, representing the urban overheating respect to the countryside surrounding the city. This book includes 18 papers representing the state of the art of detection, assessment mitigation and adaption to urban overheating. Advanced methods, strategies and technologies are here analyzed including relevant issues as: the role of urban materials and fabrics on urban climate and their potential mitigation, the impact of greenery and vegetation to reduce urban temperatures and improve the thermal comfort, the role the urban geometry in the air temperature rise, the use of satellite and ground data to assess and quantify the urban overheating and develop mitigation solutions, calculation methods and application to predict and assess mitigation scenarios. The outcomes of the book are thus relevant for a wide multidisciplinary audience, including: environmental scientists and engineers, architect and urban planners, policy makers and students.
The book reviews and reports the recent progress and knowledge on the specific impact of current and projected urban overheating as well as of the urban mitigation technologies on mortality and morbidity and urban vulnerability. It presents recent data and developments on the topic reported by some of the more distinguished researchers in this area. In parallel, it discusses new findings related to the characteristics and the magnitude of urban overheating and reports and analyzes the recent knowledge on the synergies between urban heat island and heatwaves. This book helps to advance our understanding on the interaction between Urban Heat Island (UHI) and overheating as well as their impact on energy demand and public health globally. Exploring the interaction between UHI and energy consumption requires the understanding on the dynamics of UHI intensity and air pollution index in different land use and how such interactions may vary in different cities in the world. Moreover, this book focuses on different cities in Australia, Austria, Belgium, Brazil, Canada, Cyprus, Greece, Hong Kong, India, Asia, Spain, UK, and USA.
This edited book provides a solid foundation for future research on cooling cities, climate change impacts on cities and urban environments, and innovative mitigation and adaptation strategies. With ever-increasing climate change impacts on our living environments and continuous calamities and natural disasters around the world, we urge for new approaches, apt action, and adequate support to boost cooling strategies for the built environments. To achieve this goal, research, practice, and policy could do much more to provide us with new pathways to achieve sustainable development. This book is a comprehensive collection of theoretical perspectives and global case study examples focused on three core areas of (1) concepts, theories, and trends, (2) mitigation and adaptation strategies, and (3) policies. The book is of use to various stakeholders and more importantly to urban specialists, planners and designers, policymakers, academics, practitioners, and developers. We urge them to mitigate climate change before it gets too late. We are confident the book could provide readers with new ideas, strategies, and directions that could lighten up the path toward new actions, policies, and innovation.
