Ken Yeang reconstructs and revisions how and why our current design approach and perception of architecture must radically change if we are to ensure a sustainable future. He argues forcefully that this can only be achieved by adopting the environmentalist's view that, aesthetics apart, regards our environment simply as an assembly of materials (mostly transported over long distances), that are transciently concentrated on to a single locality and used for living, working and leisure whose footprints affect that locality's ecology and whose eventual disposal has to be accommodated somewhere in the biosphere.

This manual offers clear instructions to designers on how to design, build and use a green sustainable architecture. The aim is to produce and maintain ecosystem-like structures and systems whose content and outputs not only integrate benignly with the natural environment, but whose built form and systems function with sensitivity to the locality's ecology as well in relation to global biospheric processes, and contribute positively to biodiversity (as opposed to reducing it). The goal is structures and systems that are low consumers of non-renewable resources, built with materials that have low ecological consequences and are designed to facilitate disassembly, continuous reuse and recycling a (a cyclic process that mimics the way ecosystems recycle materials), and that at the end of their useful lives can be reintegrated seamlessly back into the natural environment. Each of these aspects (and other attendant ones) is examined in detail with regards to how they influence design and planning.

Ecodesign provides designers with a comprehensive set of strategies for approaching ecological design and planning combined with in-depth analysis and research material not found elsewhere.
