The form and activities of the urban environment effect its microclimate in different ways. The accelerating urbanization worldwide in general, and in Israel in particular, combined with global climate warming, intensify these phenomena.  In this course the  different aspects of urban micro-climate will be presented, by comparison to natural or low-density habitats. Methods available to the designer and planner will be shown that can offset or mitigate negative urban microclimate phenomena. In addition evolving/emerging climate scenarios will be presented and possible ways to face them.
