We have developed the Green Browser to support a team of designers to collaboratively construct and share the product life cycle information for environmentally conscious design. We developed the ReqC model (Requirement-Centered Model) and the GLC model (Green Life-Cycle Model) for structuring design information in the Green Browser. The system allows the design team to construct the GLC model by chunking discourse and assigning types. It provides a visual presentation of the concept and scenario, and allows the user outside the team to share the model across different computer environments. We used Java2 and CORBA for system implementation. To test implementation of the system, we built a GLC model by using data collected in an industrial design project.
