It's more important than ever to take control electricity consumption in residential sector towards low carbon society. We started supplying an advisory system on “i-cosmos” which is experimental field about 230 households participating in. The advisory system is useful for electricity saving and well-reflecting reality, based on the social psychological approach. The system supplies the daily targets for electricity use in each households calculated by the linear regression model based on the past 8 weeks electricity consumption, temperature and dummy variables (0=weekday 1=weekend & holiday). In addition, the grouped household target was also showed in the system aimed to stimulate a social responsibility norm and self-efficacy based on psychological measure. The purpose of this study is to test the effectiveness of the advisory system and the daily targets for electricity use. The electricity consumption in 7 household accessing to the advisory system everyday was compared with that in 70 households having no access to it as a preliminary experiment. The result showed the effect of advisory system was an average 6-7% for saving. Especially the effect of grouped target was more than that of individual target. A questionnaire survey indicated that the social responsibility norm especially contributed to the electricity-saving action.
