[Nature on Earth continually cycles itself through the use of energy, which comes] from outside the system in the form of perpetual solar income. Not only does nature operate on "current income," it does not mine or extract energy from the past, it does not use its capital resrves, and it does not borrow from the future. [Designers must begin to use these same principles.]
. . .
[Discussing a day care center built for the City of Frankfurt:] Because of the solar hot-water collectors, we asked that a public laundry be added to the program so that parents could wash clothes while awaiting their children in school. Because of advances in glazing, we are able to create a day-care center that requires no fossil fuels for operating the heating or cooling. Fifty years from now, when fossil fuels will be scarce, there will be hot water for the community, a social center, and the building will have paid back the energy "borrowed" for its construction.
