This book explores the relationship between critical urban form and fabric parameters and urban microclimate in the high-rise urban environment that prevails in Asian megacities. It reviews the latest advances in urban climate research, with a focus on the challenges in terms of outdoor space comfort, health, and livability posed by the high-rise and high-density development in emerging Asian megacities. It proposes an integrated framework, includes a series of studies on high-rise residential and non-residential urban neighborhoods and districts, and suggests the thermal atlas methodology as a useful climate-responsive design tool for both urban designer and architects.
