William McDonough on sustainability in Architecture….
What is sustainability? Sustainability is a descriptive term for a range of cultural responses to the environmental impacts of economic growth. It is often defined as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” Described in this way, sustainability is just a minimum precondition of survival-not very inspiring. More richly defined, it as an intelligent, creative, and hopeful stance towards the future. In Jeffersonian terms, we might say sustainability is an appreciation for the legacy of your designs, an interest in the long-term health of nature and human culture.
