Abstract
The aim of the collaborative research program “W-BRIDGE” is to design, implement, and develop environmental activity models. W-BRIDGE has discovered various environmental projects through public invitation. By supporting these projects, W-BRIDGE builds models that can be widely implemented in society. In order to solve environmental problems with low economical rationality, the projects involved in W-BRIDGE focus on environmental as much as economical issues. A Co-design approach is taken in the process, which means the projects are improved and transformed from the initial proposals to be more effective and practical models. This report analyzes the effects of the Co-design approach implemented through these projects over the past 10 years.
