Publisher Summary Envisioning a better future requires a dream and the chapter outlines the fact that it includes improving our quality of life while practicing sustainable development. Much of today's built environment is not about sustainability but about improving a bottom line or satisfying an individual's aesthetic preference. Profit and aesthetics are important. The balance between an individual's preferences and a need to be good stewards of our quality of life and planet health can be achieved. Creating this balance is the responsibility of the design and engineering professional. Seven principles such as building natural form, interconnectivity, service, adaptability, Interdependence, and performance are outlined. Generally, principles are abstract, and thus some tools to aid in their definitions are used, illustrated with a diagram to explain their meaning. Different examples are offered from the small scale of a window to the large scale of a community to explain how the principle can be manifest. Finally, a means to measure each principle, as a way to create more clarity and distinction among them is discussed.
