  17. 17. 171. It is important to keep communication with the residents forcommunity-oriented demonstration project.2. It is effective to show concrete activities of the staffs to theresidents in order to obtain their understanding.A temporary office with staffs Staffs stayed there in every daytime. Staffs walked around to check equipments installed at each houseperiodically.Common rules between the residents and the project organizer (example) Staffs wore uniform when attending visitors.Ideas for obtaining the full understanding of the residents to the project:These actions contributed to close communication with the residents.1.
