Maximizing readers' insights into urban and architectural environmental planning with consideration for the thermal environment, this work highlights how various urban heat-island strategies have been developed and their effectiveness in urban areas. Specific measures to combat the urban heat-island phenomenon, including improvement of surface cover, reduction of exhaust heat, improvement of ventilation are summarized and various heat-island measurement technologies, which have been proposed in recent years, are organized systematically based on surface- heat budget and surface boundary layer models. With suggestions for the selection of appropriate heat-island technologies depending on the location, this book elucidates the relationship between the thermal environment and urban block form characteristics. Covering the latest research findings, this book is of interest for all those concerned with environmentally friendly urban and architectural planning.
