In environmental design, an important point is that each person concerned deals with a specific aspect of a project, and it is important these people discuss with, arrive at consensus, and advance steadily. One general problem in this environmental initial design stage that should be mentioned is that of concentrating only on the act of building, "field and facility". That is, the human activity, such as use, maintenance management, etc. after construction, and building usage are seldom considered. The purpose of the research is to make sharing the image of "human activity" easy within a team, and the research proposes media which support this as part of a design technique which performs examination and proposal smoothly, and can examine "field and facility" continuously.
