This course explores the principles and practice of sustainable development from the building and site to the city and region.  This exploration takes place while considering national and global implications.  Sustainability is NOT simply concerned with the natural environment. Instead, sustainable practices place equal weight on environmental preservation, economic feasibility, and social equity to achieve long-term viability. For the purposes of this course, sustainability is defined as multi-faceted, multi-sectoral, and multi-temporal. It is the balancing of social, economic, and environmental issues through private-, public-, global and nonprofit sector efforts for today and for generations to come. Therefore a primary purpose of this course is to assess the appropriate themes and scales at which sustainable practices can be achieved.
