Rapid urbanization in the tropics has brought in its wake many hitherto unknown changes to humans, animals and plants and the physical environment. Many of these changes are well studied by researchers in diverse fields such as medicine, agriculture and engineering. However, the climatic effect of urbanization has not been understood nor the knowledge base applied by urban designers, planners, architects and engineers. In particular, the energy and bio-climatic implications of changes induced by urbanization have received very little attention in urban design and planning. This book lays out the problem of tropical urban climate anomaly and points to possibilities of mitigating these changes through design and planning options. An Urban Approach To Climate Sensitive Design brings together the emerging literature on climate-sensitive urban design and places it in a tropical context. The physical processes behind changing urban climate are clearly illustrated.
The book presents a general background to the environmental issues facing tropical building designers - energy consumption and comfort implication of buildings and an overview of microclimate changes brought about by urbanization. New ways of looking at urban design are presented from a climatic design perspective. The focus of the book is design strategies that can mitigate the negative impacts of tropical urban climate. Three such design goals are: radiant cooling, ventilation and evaporative cooling. Simple design strategies further develop the conceptual ideas, including discussion of a D hadow umbrella D " or sun avoidance scheme and demonstrates its applicability to the equatorial tropics. In order to make the discussions on urban energy use and energy efficiency complete, the book closes the discussions with a series of strategies that facilitate movement between inter-connected urban activity patterns in a climatically suitable manner. Urbanization in tropical regions is beginning to gather momentum and is likely to intensify in the near future. This book fills a crucial gap in the knowledge of climate-sensitive urban design in a tropical context.
This comprehensive reference will be welcomed by student and practising architects as well as other built environment professionals engaged with the environmental effects of building in worldwide warm and humid climates
Dr. Rohinton Emmanuel is a University teacher and researcher from Sri Lanka, with a Ph.D in urban climatology from the University of Michigan and has also taught in the US and Sweden. His core interests in studying the environmental changes brought about by urbanization in the warm, humid tropics. For nearly 13 years he has extensively researched climate changes in cities with the long-term goal of developing urban environmental monitoring indices that facilitate environment-sensitive urban design in the tropics. He has an extensive record of research and publications on building climatology and urban climate changes.
