The Materials Book

384 Example: Graph from Anthony Froshaug’s ulm , no. 4, 1959, pp. 63–65 Contributed by: Jesko Fezer, Germany The Power of Nothing: Sometimes not building is the right thing to do The most sustainable material is no material at all. No natural resources are consumed. No energy is used. No emissions are released. No waste is produced. But using no materials means not building, or adapting what’s already there. That can mean delay, postponement, or non- planning instead of designing and building. Or it can mean determining how we can best use a given space and the resources we fill it with. It might mean getting creative and using an existing or planned structure to serve multiple purposes. Each project must be individually assessed, minimized, and adjusted to meet the needs of various users. Anthony Froshaug’s visual method, first developed in the 1950s, helps achieve those goals—and that’s the key to sustainability.
