Stahel have emphasized, postindustrial efficiency is far more about organizational factors and a careful consideration of end-use. The production of quality and the production of service are, in practice, virtually the same thing. They demand the creation of the closed-loop lake economy described in Chapter I, but they also require, and are made possible by, a transformation in the role of culture in the economy, which is the root of the information revolution. Qualitative value is specific to contextin contrast to quantitative value (like the dollar) that is homogeneous and abstract. Qualitative value requires lots of knowledge about context. Ironically, quality (i.e. regenerative wealth) also entails much more quantitative knowledge than does accumulation. Similarly, post-materialist value requires far greater awareness about material factors and flows than the old productivist industrial economy ever did. This is particularly obvious in building where life-cycle assessment and other forms of environmental impact evaluation are becoming commonplace. Targeting end-use, creating organizational efficiencies, moving with natural flows, and understanding the multi-dimensional impacts of our activities demands substantially more information than does simple financial payback.
