A living-sphere approach for locally oriented sustainable design

Achieving a sustainable consumption and production pattern is one of the United Nation's sustainable development goals for 2030. To achieve this, it is necessary to consider the environmental burden from a product life cycle and the quality of life of the consumer. In this study, a systematic approach for connecting basic human needs and the product development process, called the living-sphere approach, is proposed. This approach is intended to encompass the complete relationship between region-specific basic needs and durable products. In this approach, value graphs, which visualize the value system of products, are connected to satisfiers fulfilling the basic needs set out by Max-Neef. A value graph links satisfiers and the traditional product development process. The significance of the proposed approach is twofold. First, improving quality of daily life and traditional product development are combined in the same framework. Second, the design of single products and the total optimization of multi-products are supported at the requirement level.
