Louise St Pierre sent me this terrific catalog of student work that focuses around Product Service Systems.
The Learning Network on Sustainability, or LeNS, is a platform for developing university level curriculum for teaching sustainable product-service design. Originally focused around design schools in Europe and Asia, it is also an open-source concept project open to all schools seeking to build curriculum around sustainability. Their catalogue outlines their objectives and features concepts from their student design competition.
In the LeNS system, all solutions demonstrate practical applications of systems thinking in design. Material flows are considered as well as interaction of people within the solution and environmental impact. Their website also offers tools and examples for building service design projects and systems maps.
