compared with those living in sprawling suburbs. The concept of circular flow land use management has also been introduced in Europe to promote sustainable land use patterns that strive for compact cities and a reduction of greenfield land taken by urban sprawl. Sustainable architecture, a recent movement of New Classical Architecture, promotes a sustainable approach towards construction that appreciates and develops smart growth, walkability, vernacular tradition, and classical design. This in contrast to modernist and globally uniform architecture and opposes solitary housing estates and suburban sprawl. Both trends started in the 1980s. Individual buildings (LEED) The Leadership in Energy and Environmental Design (LEED) Green Building Rating System encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria. LEED, or Leadership in Energy and Environmental Design, is an internationally recognized green building certification system. LEED recognizes whole building sustainable design by identifying key areas of excellence including: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, Locations & Linkages, Awareness and Education, Innovation in Design, Regional Priority. In order for a building to become LEED certified sustainability needs to be prioritized in design, construction, and use. One example of sustainable design would be including a certified wood like bamboo. Bamboo is fast growing and has an incredible replacement rate after being harvested. By far the most credits are rewarded for optimizing energy performance. This promotes innovative thinking about alternative forms of energy and encourages increased efficiency. A new district in Helsinki, Finland is being made almost entirely using timber. This timber is a form of a Laminated Veneer Lumbar (LVL) that has high standards of fire resistance. The idea is that wood construction has a much smaller footprint than concrete and steel construction and thus, this project is going to take Finland's timber architecture to new heights of sustainability. Sustainable Sites Initiative (SSI) Sustainable Sites Initiative, a combined effort of the American Society of Landscape Architects, The Lady Bird Johnson Wildflower Center at The University of Texas at Austin, and the United States Botanic Garden, is a voluntary national guideline and performance benchmark for sustainable land design, construction and maintenance practices. The building principles of SSI are to design with nature and culture, use a decision-making hierarchy of preservation, conservation, and regeneration, use a system thinking approach, provide regenerative systems, support
