The following research and thesis was presented to the Landscape Architecture Program at Chatham University in partial fulfillment of the requirements for the degree of Master of Landscape Architecture in April 2010. The goal of the study was to support the need to increase the landscape principles that are represented in green building certification. Buildings can be certified by the LEED Rating System and still attain none of the landscape principles deemed necessary to a healthy environment by this research.
Evaluating vegetation, site, and location-related credits achieved by LEED Certified Buildings
The green building movement is one response to the environmental impacts resulting from the built environment; it aims to reduce material consumption and waste, while improving energy efficiency and occupant health. The U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) Green Building Rating System has become a base line for sustainable building in the United States.
Though LEED is increasing the number of high performing buildings, thus reducing the energy use and waste production resulting from the built environment, without a stronger focus on the exterior performance these certified buildings may not be providing the urban environment with the ecosystem services necessary for healthy cities. Douglas Farr, author of Sustainable Urbanism, points out that a shortcoming of the LEED Rating System is that the emphasis is put on just the building by stating that “a certified green building isn’t really a positive for the environment when it turns out to be surrounded by a massive paved parking lot” (2008, p. 29).
