This seminar will focus on how physical design can improve sustainability. It will be broken down into: Green Buildings, Green Urbanism, and Smart Growth Planning. We will begin by looking at which types of construction actually constitute Green Buildings and which of these are the most effective. Our look at Green Urbanism will focus on existing cities and towns, covering how urban design and transportation can promote sustainability. Finally, Smart Growth planning concepts and a survey of New Urbanism will be discussed, including how these closely allied approaches are attempts to guide new growth in a more sensitive manner.
